Our Range of Plumbing Products

Gerpex Press Fitting Range

The Gerpex system has been designed for use with hot and cold water, heating, chilled water and compressed air sytems.

Gerpex Multi-Layer Composite Pipe can be used in both traditional branch plumbing and point to point plumbing in conjunction with Emmeti manifold systems. It is suitable for use in both domestic and commercial projects and is fully WRAS approved for use in hot and cold water supplies.

For branch plumbing applications, the system includes high quality metal press and compression fittings, together with tooling and a full range of accessories. Gerpex MLCP is also fully compatible with the Emmeti range of hot and cold water and heating manifolds for use in point to point installations using the patented Emmeti Monoblocco compression fittings.

The wide range of pipe sizes, fittings, accessories and various fastening options make the Gerpex system a complete and highly reliable solution for any project.

Gerpex Multi-layer Composite Pipe

Gerpex Multi-Layer Composite Pipe (MLCP) is the optimum solution for modern building projects offering all of the advantages of both plastic and metal pipes combined with excellent value for money and peace of mind. Gerpex can be used in a wide range of applications including hot and cold water systems, heating (wall hung radiator and underfloor heating), chilled water and compressed air. The pipe is available in a range of sizes from 16-63mm making it ideal for both domestic and commercial applications.

Gerpex Multi-Layer Composite Pipe is made of composite material through a technologically advanced process in which an inner layer of cross-linked PE-Xb (polyethylene) pipe is bonded to a butt welded aluminium core with outer layer of PE-Xb (up to 32mm) or PE-HD (from 40 up to 63mm). This production process is what gives Gerpex its high temperature and pressure characteristics. The internal aluminium layer provides rigidity, form retention and a solid oxygen barrier to prevent internal corrosion of heating system components such as heat exchangers, pumps and radiators.

The products are fully WRAS approved for use with hot and cold water systems and the range includes coils up to 500m, 4m straight bars and insulated coils

Gerpex Press Fittings

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 steel fittings. The positive sealing action of the press system will also give greater confidence to the installer, developer and end user than push fittings.

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

Gerpex Plumbing Tools

Gerpex Tooling

A range of pressing tools and jaws to suit 16mm up to 63mm with multi-profile compatible tooling. Also included are pipe preparation, cutting and bending tools. Includes battery operated, REMS Mini and Akku-Press as well as replacement jaws.

Domestic Hot & Cold Manifolds

By using an Emmeti manifold system in a point to point plumbing configuration you can greatly reduce the number of joints in your system, speeding up installation time and vastly reducing the chances of a leak.

A manifold system also allows you to reduce certain pipe sizes per outlet, which will save on material and installation cost (e.g. WC feed with 10mm and shower feed with 16mm).

Point to Point Manifold Plumbing

Point to point plumbing is a method of installation using a manifold to distribute hot and cold water to items of sanitaryware and appliances around the property (such as washing machines, sinks, baths and dishwashers.

Each individual outlet is supplied using a continuous length of pipe from the manifold with joints at the outlet and at the manifold only.

This reduction of joints in the system reduces installation time and vastly decreases the potential for leaks which can lead to costly repair claims and damage to reputation.

Branch vs Manifold Plumbing


•Provides you with individual isolation of outlets and appliances if required. You are able to isolate parts of the system whilst the rest remains operational, reducing disruption for installation and maintenance.

*Reduced installation time of between 30%-40% due to fewer fittings required.

• Gives you a reduction of up to 70% of joints, with virtual elimination of tees and elbows, therefore the chance of leaks both during and post installation is greatly reduced.

•Ensures that you have good accessibility in the event of a problem – limits the points at which a leak could occur to the point of use and the manifold, significantly reducing the time for fault finding.

• All joints are above ground and are easily accessible.

• Monoblocco connectors allow you to tailor the outlet sizes for different pipe sizes going to different outlets. You can therefore optimise the pipe size to be installed per outlet.

• Allows you to adjust the flow rates to individual outlets.

• Allows an easier understanding of water system schematics in relation to points of isolation. This will ensure future maintenance and repair can be carried out with minimum disruption.

*Only applies to Topsan and Multiplex Manifold
