JG Speedfit release aid allows a firmer grip on the collet when removing pipes. Designed, manufactured and assembled in the UK.
Provides a firmer grip on the collet demounting pipe
For use with Speedfit fittings
JG Speedfit ball valve (chrome plated) for connecting plastic or copper pipe. Using an easy to operate handle, the valve enables the flow of water to a fixture or appliance to be isolated in the event of an emergency or for maintenance work. Simply push the valve fully onto the pipe. To demount the connection, push the collet towards the body of the push-fit fitting and pull the pipe release.
The JG Speedfit ball valve (chrome plated) is up to 40% faster to install than traditional methods and is easier to use in confined spaces by removing the need for hot works and tools. Designed, manufactured and assembled in the UK.
Instant push-fit service valve with integrated isolation handle
Durable brass chrome plated body
Red and blue indices for easy identification of water supply
Install and demount in seconds without tools
Safe flame-free installation, with no hot works, glue or flux
Grip & Seal collet with stainless steel teeth and main O-Ring seal
Compatible with Speedfit PEX and polybutylene plastic pipe (inserts required) and copper pipe
Suitable for hot and cold water and central heating systems
JG Layflat Polybutylene Barrier Pipe offers greater flexibility than standard polybutylene and PEX pipe, making long pipe runs and cabling through joists faster and easier. The flexibility of the pipe reduces the need for fittings significantly compared to traditional copper pipe systems, which in turn delivers labour and cost savings.
When removed from the coil, the pipe ‘lays flat and stays flat’ meaning there are no issues with the pipe retaining its memory and trying to coil back into place. The pipe is made up of 5 layers, the centre of which is a coloured oxygen barrier to prevent the ingress of air into the system, reducing the effect of corrosion on metal components. Layflat is available in standard UK plumbing sizes that reduces wastage compared to non-UK sizes. Designed, manufactured and assembled in the UK.
Lightweight flexible pipe makes cabling fast and simple
Less fittings, less labour and material costs, less potential leak points
Safe and non-toxic material with no need for hot works
Resists corrosion and scale build up, reducing pin hole leaks and blockages
Pipe elasticity reduces the chance of burst pipes in freezing conditions
Considerably reduces the noise of water hammer

Suitable for hot and cold water and central heating systems
Manufactured to the highest standards, JG LowFit™ underfloor heating manifolds are made from stainless steel and are available in a range of sizes from 2 to 12 ports.
Fast and simple to install, JG LowFit™ manifolds uniquely feature JG Speedfit push-fit connections and come with a pre-mounted bracket and vibration isolation mount. Manifolds can also be assembled to suit left or right-hand supply.
Each manifold is supplied fully assembled with flow and return rails, adjustable flow meters, an automatic air vent and fill valve. Protective dust caps are supplied on the return rail, which can be removed when installing circuit actuator valves to open and close the flow of water to each pipe loop.
High performance stainless steel manifold
Fast and simple installation using 12mm Speedfit connections eliminating the need for further reducing adaptors.
Easy to fit due to pre-mounted brackets and vibration isolation mount
Integral Automatic Air Vent discharges air that could impact circulation
Valves on the return manifold are compatible with thermoelectric heads
Rail valves on the return rail allow circuit actuators to be easily connected
Versatile assembly for left or right-hand supply
Suitable for use with JG Speedfit PEX and polybutylene barrier pipe (inserts required)
JG Speedfit collet locking clip prevents the accidental release of a pipe from a standard push-fit fitting. Red and blue options available to provide colour coding of hot and cold water pipes. Designed, manufactured and assembled in the UK.
Colour coded for easy identification of service type
For use with Speedfit fittings
Suitable for hot and cold water and central heating systems
For I beam joists to be used with composite joists and are fixed from below. Speedfit Pipe is fixed in the grooves of the plates, insulation is placed in the void below the plates to minimise downward heatloss.

JG Speedfit pipe in pipe is ideal for short through wall pipe runs where a firmer pipe material is an advantage. The flexibility of the pipe reduces the need for fittings significantly compared to traditional copper pipe systems, which in turn delivers labour and cost savings.
The JG Speedfit pipe in pipe is made of 5 layers, the centre of which is a blue coloured oxygen barrier that prevents the ingress of air into the system, reducing the effect of corrosion on metal components. Due to its low thermal conductivity, when carrying hot water, PEX pipe is cooler and therefore safer to touch. The pipe comes encased in protective conduit pipe to protect it from potential damage when run through partitions or walls. Designed, manufactured and assembled in the UK.
