Plumbfit GPF is the grey, totally flexible plumbing system from Davant Products, the result of considerable investment in research and development, GPF is tailor made for the professional plumbing and heating installer who wants a high quality system that is simple to fit, durable in use, yet competitively priced.

High Level of Specification

Manufactured in accordance with the highest European Quality Standards, including BS EN ISO 9002, the Plumbfit polybutylene pipe and GPF fittings system conforms to BS7291 Parts 1 and 2. Accordingly, the system holds the British Standard Institute Kitemark classification 'S'. Plumbfit GPF polybutylene system is one of few systems on the market to have achieved this.

Comprehensive range

The GPF PB system offers a comprehensive choice of pipe and fittings in 10mm, 15mm, 22mm and 28mm sizes, suitable for all hot and cold plumbing and central heating systems. It can be used in both sealed and open vented systems and has been designed to withstand constant pressure at high temperatures. The combination of low thermal conductivity and high corrosion resistance makes it ideal for use in central heating systems.

Easy to Handle and Fit

The GPF polybutylene system offers the installer major advantages. The flexible nature of the pipeallows a cabling option, which speeds up pipework routing significantly.

It will also cable through joists easily, thus dispensing with the time consuming task of pipe bending and joint compressing in confined areas. GPF PB piping is so flexible that it can be bent to 8 times its diameter without the need for a joint.

Few tools are needed to complete even the most complex pipework systems. Joints are push-fit for simplicity and speed of installation. Nothing could be more simple, cleaner or safer. Plumbfit strongly recommends the use of lubricants which reduces installation time and ensures a perfect joint, first time, every time.

Using GPF With Other Pipes and Fittings

The GPF polybutylene system is extremely versatile and can be used with all metric sized copper pipe manufactured to BS2874 and compression fittings manufactured to BS864.
