Gerpex Press fittings

A range of WRAS approved, brass bodied, press fittings for use with Emmeti Gerpex MLCP. Profiles are TH for all sizes, B up to 32mm, U, H and F up to 20mm.

Gerpex Press Fittings have been developed to be used with Multi-Layer Composite Pipe as a clean, simple and more efficient alternative to traditional jointing methods such as soldered copper and threaded stainless fittings. With a definite press of each fitting the system will also give more confidence to the installer, developer and end user than push fittings.

The brass bodied fittings with double o-ring technology and combined sight hole, dialectric ring and jaw alignment collar help to ensure that the pipe is fully inserted and pressed correctly, every time.

FAQS

I can see that TH profiles are WRAS approved with Gerpex Press Fittings. Can I use other jaw profiles?
Gerpex Press Fittings are WRAS approved when use in conjunction with TH profile pressing jaws. However the fittings are fully compatible with B profile up to 32mm and U, H & F up to 20mm sizes. B, U, H & F profiles don’t have the WRAS approval with Gerpex Press Fittings so please check potable water requirements for the project with the architect, project manager, etc as appropriate before using these jaw profiles.

Does Gerpex Multi-layer Composite Pipe need metal tracer tapes as per the NHBC requirements for metal detection?
No, the aluminium core within the Gerpex pipe can be picked up with a metal pipe detector.

I see that Gerpex Multi-layer Composite Pipe has a butt welded aluminium core, is this better than products with lapped joints?
The butt welded aluminium core ensures a consistent pipe diameter and a more circular pipe cross section allowing water to travel with less resistance providing a benefit.

Can I connect Gerpex Multi-layer Composite Pipe directly to a boiler?
Most boiler manufactures require a minimum length of a metal pipe before allowing connection to MLCP. Please check with the boiler manufacturer’s instructions before considering any connections directly to the boiler. At Emmeti we have developed MLCP to copper fittings for ease of connection.

Can I use Gerpex Multi-layer Composite Pipe for underfloor heating loops?
Yes it’s perfectly possible to use 16mm Gerpex for example in UFH applications. However, at Emmeti we also offer two other pipe products specifically for UFH (Alpert MLCP and PE-Xa barrier pipe). Both of these products may provide a more cost effective solution for this particular application.
