How Push-Fit Multi-Seal Works

Speedfit’s core is its multi-seal push-fit mechanism ensuring leak-proof joins. This technology allows for secure connections without the need for tools or adhesives.

The internal gripping mechanism holds pipes firmly in place, while multiple sealing points prevent leaks even under varying pressure and temperature conditions. Seal integrity endures pipe movement and thermal cycles.

Available in plastic or brass, Speedfit covers every application need. Engineered and tested to exacting standards, each fitting is QC-certified.

Universal Pipe Compatibility

Speedfit adapts to copper, CPVC, PEX, and tubing like PE, nylon, and PU.

Copper Pipe Connections

Speedfit locks onto copper for perfect, drip-free seals. This compatibility is crucial for mixed-material plumbing systems where copper pipes are used alongside other materials.

Connecting to Plastic Pipes

Designed for plastic pipe dynamics without losing seal integrity. Proper preparation of plastic pipes is essential for optimal connection, including cutting them to the correct length and ensuring they are free from debris.

This tool-free installation process not only saves time but also reduces the risk of fire, burns, or chemical exposure, enhancing safety. Homeowners love the ease and speed of tool-free installs.

40% Faster Installation Compared to Traditional Methods

Speedfit installs finish 40% quicker than solder or thread. This significant reduction in installation time is achieved by eliminating several steps required with traditional methods like soldering or threaded connections.

Soldering calls for flux, flame, and patience—plus cleanup. In contrast, John Guest Speedfit fittings simplify the process to just a few straightforward steps: cut the pipe to size, deburr if necessary, and push the fitting onto the pipe.

Faster installs mean lower labor costs and happier DIYers. Emergency fixes finish sooner, minimizing damage and downtime.
