Hydraulic fittings connect the wires in the hydraulic system, such as hoses and pipes. Most fittings have a male and female component connected to form a connection. These connections help control and guide the flow of hydraulic fluid in the conductor while preventing leakage and maintaining pressure.
There are mainly five well-known hydraulic fitting suppliers in the world. They are Bosch Rexroth, Daikin Industries, Eaton, Kawasaki Heavy Industries, Parker Hannifin. We are familiar with these five major hydraulic fittings supplier brands, as well as some Hydraulic accessories companies we do not know, how we choose to follow them and buy their products. Please be patient and read the suggestions.
How to find a good supplier of hose fitting?
Hydraulic hose fittings and adapters are widely used in hydraulic systems to connect hoses to other hydraulic components such as valves, actuators, and cylinders to allow fluid conveyance. Although hose fittings and adaptors seem to be very tiny parts of the hydraulic systems, they perform very critical roles in providing strong and secure connections by maintaining safe pressure and preventing potential leakage.
Unfortunately, hydraulic fittings and adapters of wrong choice will cause slow down, or &#;strikes&#; of working hydraulic systems, or even worse, accidents and casualties. To avoid all these hassle and hazard, it is essential to find suppliers who are capable of supplying hydraulic fittings and adapters that are strong, reliable, and versatile enough to perform safely and effectively in respective applications.
And here are some tips about how to do so:
China is the biggest exporter of steel fittings and adapters around the world. No matter you are buying from local, or foreign countries such as Korea, Italy, Turkey, etc, it would make sense to start sourcing from China. They will make great substitutes.
If you already started buying from China, here are some keys to ask before finalizing your supplier's list.
Material
Carbon steel: #45, #35, #20, 08F. Price could vary greatly with different materials been used, with most expensive #20 #35 and least expensive 08F. Sometimes you getting cheaper ones is only because your supplier is using cheap steel. It is not always a bad case as you could happen to just need cheap steel. Let's say your hydraulic system is not very demanding in pressure, it is economic to use 08F rather than #20 #35. Nevertheless, if your hydraulic application is critical in pressure, it is rational to buy #20 #35 #45 to avoid any potential explosion.
Surface Treatment (Electroplate)
The most common plate is zinc plating, also known as Cr3+ plating. However, the price could again differentiate with same plating. Therefore, it is smart to ask about corrosion resistance time, also known as salt spray test hour. Usually, the industry standard is 96 hours, but prices make differences. It could be as low as 72 hours, or as long as 560 hours or above, depends on your specific needs. On the other hand, there is other kinds of plating such as Nickle zinc plating, which is more expensive and of course for more demanding applications.
Standards
The most popular standards of hose fittings and adapters are SAE and Eaton. They differ in hexagons as people in different countries use different wrenches. Overall SAE and Eaton standards are interchangeable, but countries do have their own preferences. Therefore, it would be wise to make sure which standards you use and inquire accordingly.
Forge Plant
It is important for your supplier to have his/her own forge plant to lower home costs, maintain consistent product quality, and fasten lead time.
Keep these in mind and you will probably find a great supplier.
Benefits of choosing Chinese hydraulic hoses
There are many manufacturers and suppliers of large and medium hydraulic hose fittings worldwide. China is currently the world's largest exporter of hoses. What are the benefits of choosing Chinese hydraulic hoses?
Low price
The price of hydraulic hoses in China is very attractive. Distributors go to China to buy hoses and fittings at a lower cost and sell locally to earn high profits. Choosing a Chinese manufacturer can bring him a much richer profit than hydraulic parts suppliers in other countries.

How to choose a manufacturer of hydraulic hoses and accessories in China
Hydraulic Fittings Price
When it comes to price, you may often hear suppliers asking how much you want to buy. As you can see, the reason is that mass production is more efficient and less expensive for the factory.
If a production line needs to switch orders back and forth, efficiency suffers. If you are buying in bulk, you can ask your Chinese supplier for more price support.
Quality of hydraulic fittings
One thing you should know is that components used by different suppliers can vary widely, even if they are the same hydraulic fitting.
Delivery of hydraulic Fittings
Third, timely delivery will minimize your out-of-stocks. Especially if you are doing some marketing activities, we should prevent late delivery.
In addition to the above three aspects that need attention, there are some places that need special attention.
Cstomized product
Different markets have different functional requirements and specification requirements. Therefore, customization for a variety of different needs is very important.
In addition, the technology of hydraulic joint products is also more mature.
You can specify the features you want in a product and then check with the vendor to see if the product meets your needs.
Hydraulic accessories supplier qualification
Hydraulic fittings are a production machine with very high barriers to entry. For European countries, CE certificate is mandatory. For the US market, both exporters and importers are required to register with the FDA if they sell as "hydraulic accessories".
Having said that, you should verify their eligibility.
After-sales service
Besides product, price and delivery time, the service of the supplier is also important. Whether it's answering your questions in a timely manner or helping you with after-sales issues, these can impact your business operations.
You can observe the supplier's performance during the communication process to see if they have these experiences and the ability to provide good service.

So, i thought i'd put as much of the info i have (none written by me, just a compilation from various sources) on both the AN/NTP fittings and the hoses in one thread. I know the info is sometimes hard to find and could be confusing as hell on the exact components you may need if you've never dealt with this. Dealing with AN fittings and corresponding lines can certainly become PITA, incorrectly done will certainly cause leaks or worse and these not being cheap one should know what they're doing before attempting making their own lines.--------------------------------------------------------------------------**************(i don't know which brands are better quality, so folks please speak up!)************** An always useful Wiki info :)AN (Army-Navy) Sizes were established by the Aerospace industry years ago and were designated O.D. of the rigid metal tube that each size fitting is used with. (The chart to the right will clarify this point.)The numbers assigned equate to the O.D. (outside diameters) of the tubing in 1/16&#;. Since tubing and hoses are to be found with assorted wall thicknesses, we can now understand that the designated size number does not necessarily tell you how large the inside diameter will be. (For example, the inside diameter of an Earl&#;s size 6 hose end is nearly as large as the inside diameter of some manufacturers&#; -8 hose ends.)Each AN size number has its own standard thread size which can be seen in column three of the chart. Again, these are the same thread sizes that have been used in aircraft and industrial applications for many years.Some of the most popular adapter fittings shown in their catalog are AN to NPT adapters. While many variations are offered, column four in the chart shows which AN size corresponds to each NPT size when inside diameters (flow dimensions) are considered.All Earl&#;s Swivel-Seal hose ends are designed to provide little or no restriction when used with the corresponding AN fitting size. We also offer a number of Metric and British Standard Pipe threads to AN fitting adapters.******For war zones like Vietnam the US military required a range of strong, light, high temperature hose assemblies that could be serviced in the field for use in oil, fuel and hydraulic applications, mainly on helicopters. Aeroquip came up with the AE701 hose and "Little gem" ® fittings, these eventually found their way onto the war surplus market and were seized upon by the motor racing fraternity.The supply of these hoses and fittings gradually dried up, and a new industry came into being making compatible hose and fittings. Earls "Permo-o-flex", Goodridge "200" and Keith Black "Kb-plus" are examples. Aeroquip returned to the market with the hose renamed "FC333 Racing hose".All these hoses and fittings are interchangeable but only assemblies from one "manufacturer" have any guarantee. Despite the interchangeability there are differences in design of the method of fitting and the means of achieving a "double swivel" on angled fittings.In the beginning the Aeroquip " little Gem " fittings had a cutter style attachment. which was suited to coping with the high pressures in hydraulic systems and assembly by trained personnel. For the less demanding motorsport use they opted for the far more user friendly compression style fitting, unlike the competition which stayed with the old design.Aeroquip were very late in producing a double swivel angled fitting but when they did they overcame problems associated with existing designs where to achieve a swivel the fitting had to turn in the hose thus breaking the primary seal and often when sticking occurred the secondary seal as well.Complies with FIA regulations. Used by professional teams who will only consider the best for fuel, oil and airjack systems.MOQUIP aero hose & compact fittingsAEROQUIP racing hose & fittingsMoquip oil hoses and fittings are economically priced and suitable for all oil carrying purposes in vehicles except those used in competition where regulations specify a 135°C maximum temperature. (The hose will still function at these temperatures but a gradual but detectable hardening of the hose will shorten life).This is a textile hose with synthetic rubber inner tube, one layer of textile braid reinforcement and a synthetic rubber outer layer.Assembly of hose to fitting is very simple, the fitting is simply pushed into the hose, this hose has the reinforcing braid woven in such a way that the grip on the fir tree type fitting increases as the force trying to push it out increases.This hose has had a resurgence of popularity recently, especially since aluminium fittings were introduced. Some examples of this hose have a 150°C rating, however instances of the fitting blowing out of the hose at extreme temperatures have been reported on some makes (not Aeroquip), extra clamping should be considered where very high temperatures are involved.This type of hose and fitting can be interchangeable between brands but only genuine Aeroquip assemblies can be guaranteed. We can provide a stainless steel braid covering for these hoses, this does not impart any greater strength only enhanced appearance and abrasion resistance, factory swaged ferrules or finisher such as a &#;Pro clamp ® &#; must be used to hide frayed ends.Conventional brake hoses, manufactured in rubber with textile reinforcement, are permitted to have a significant amount of volumetric expansion, that is they swell under pressure, this leads to a soft feel to the brake pedal, acceptable in a road vehicle but not for competition.On racing vehicles, this has lead to the universal usage of smooth bore PTFE (Teflon ® ) hose with normally a stainless steel. This hose has the added benefit of lightness, strength, high temperature resistance and protection from stone damage.We call it " Moquip TFE ", Aeroquip " TFE racing hose " or " ", Aeroquip Aerospace " 666 ", other brand names are " Speed-Flex ", 600 ", and " 411 ". They can be had with re-useable or swaged on fittings. With the exception of Aeroquip Aerospace, hose and fittings are interchangeable between brands.Some countries, not the UK, insist on tests for brake hoses. The TFE hose assembly passes all the tests except the whiplash test which ensures that the hose is suitable for withstanding large wheel movements on vehicles doing hundreds of thousands of miles, quite sensible, but not relevant to competition motoring. Some hose specialists have recently come up with complicated assemblies allowing the hoses to pass the test, but generally speaking, they are not suitable for high mileage road usage.These hoses are also suitable for oil pressure gauge lines, fuel injection pipes, power steering hoses and, because of their high temperature capabilities, on turbocharger oil feed and return lines.Use where light weight is a primary concern. Complies with FIA regulations. Very little heat dissipation through hose which can be handled whilst containing oil at 100ºC. Unlike convoluted TFE hoses, hose bore is smooth.The hose has a special AQP neoprene inner tube, reinforced with fire retardant Nomex outer. To achieve greatest weight saving, up to 45%, use factory swaged silver and blue fittings, for on site assembly use the red and blue compression style Racing Hose fittings.Specially formed stainless steel convoluted tube with re-useable red/blue anodised aluminium fittings. Use on fuel lines, dry sump lines to and from tank where light weight and ease of installation are considerations.An extremely light hose assembly consisting of a convoluted wrapped PTFE (Teflon) liner with a Nomex covering, PTFE hoses are resistant to all types of automotive fluids. They are also available with stainless steel braid outer covering. Where the utmost weight saving is sought factory swaged fittings are used but hoses with re-useable fittings still offer a significant weight saving. There is no interchangeability of hoses and fittings between different manufacturers of convoluted TFE hose.Fittings are aluminium with anodised blue fittings and gold nuts/ferrules. Elbows have one piece bends (not brazed) and the double swivel rotates in the housing not hose. ProGold AR fittings are reusable, ProGold AC fittings are swaged at our factory.There's a huge amount of different adapters that could be used with AN fittings and all could be purchased from any of the sources above.cont. next post.
