System connections are unique mechanical pipe fittings designed to attach water pipes made of plastic, such as HDPE/PE/PEX and OPVC/PVC.
There are still many pipes older than a century in several European cities that need to be replaced because of significant leakage rates. When these pipes fail, they are frequently replaced by PE and PVC pipes, as they offer lower failure rates than other materials. To meet this need, Hawle offers System pipe connections that are perfect for plastic pipes. System pipe connections are attached to the pipes using a brass grip ring with teeth elements, providing a restraint connection for plastic pipes.

Compared to other pipe laying technologies like PE-welding, for the System installation, no special tools or machinery or specially trained personnel are needed. Cold, rainy weather or groundwater in the pit also do not affect the fast and safe System assembly. In addition to that, Hawle has a certificate from an external independent institution 100 Years Expected Lifetime.
Among other valve manufacturers of comparable mechanical connections for PE pipes, Hawle offers one of the broadest product pallets with System : Pipe connections, bends, couplings, end caps, combi- and gate valves, suited for all types of installations are all part of the Hawle System offering. System diameters might be as little as d63 or as large as d630, depending on the product.
