The HAWLE SYNOFLEX socket system provides high quality restraint connections to all common water supply pipes. The patented HAWLE-SYONFLEX secures steel, DCI, PE/PVC and AC* pipes with fully corrosion protected connections.

* Warning! A restraint connection between Synoflex and asbestos cement pipes cant be confirmed. Removal of the grip ring is not necessary.

Durable
The proven epoxy powder coating as specified by GSK (the Quality Association for the Heavy Duty Corrosion Protection of Powder Coated Valves and Fittings) provides excellent corrosion protection. Bolts, nuts, washers and locking pistons are made of A4 high grade stainless steel.

Easy to install
By pinching the quick-clamping lug, the SYNOFLEX grip ring quickly conforms to the pipe. Tighten the nuts while keeping the SYNOFLEX in correct position. Due to the bolt anchor, the bolts can be tightened with only one hand. The Molybdenum coated bolts counteract friction with the nut for easy assembly.

10 year factory warranty
Your safety is assured through decades of experience in making pipeline connections at HAWLE, backed up with a 10 year quality on all HAWLE SYNOFLEX products.

Adaptable
Improvising in the trench is easy when using HAWLE SYNOFLEX. With a tolerance of 4° angular deflection at both pipe ends, all types of pipes and the combinations thereof can be connected with HAWLE SYNOFLEX. The Molybdenum coated bolts can be extracted and inserted again on the opposite side for easy one hand tightening from the inside in areas that are too tight for wrench access.

Reliable
HAWLE SYNOFLEX ensures a restraint connection for all common pipe materials. The clamping elements holds the pipe securely without damaging it. The elastomer gasket fits snugly around the pipe, creating an effective seal. The pipe will not move inwards when tightening. Cost-saving

The HAWLE SYNOFLEX product range covers most of the installation situations. Due to its flexible range, the HAWLE SYNOFLEX saves cost by reducing the number of pipeline connectors needed in the warehouse.
