Speedfit Core Technology

The JG Speedfit plumbing system is a line of push-fit fittings, pipes, and valves designed for domestic and light commercial hot and cold-water supply, as well as central heating systems.

Its primary feature is the ability to create secure, leak-proof connections in seconds without the need for tools, heat, soldering, flux, or glue, significantly reducing installation time compared to traditional methods. The core of the system is its patented push-fit technology.

The design innovation behind John Guest’s patented push-fit technology go beyond plumbing & heating to include diverse industrial applications such as; fibre optic cabling connectors that seal microducts for high-speed data lines, drinks dispense systems for carbonated beverages with food-grade high-pressure fittings, and high-performance automotive fuel lines.

Instant Connection

Secure Grip

Watertight Seal

Demountable Design

The installer simply pushes the pipe into the fitting until it reaches a pipe stop and locks in place.

The connection can be easily released, without tools, by pushing the collet back against the fitting's body, allowing for modifications, maintenance, or reuse of components.

Internal stainless-steel teeth (collet) grip the pipe firmly to provide a strong mechanical hold.

An EPDM O-ring within the fitting creates a permanent, leak-proof seal.

How It Works

Twist & Lock

Certain fittings feature a plastic nut that can be twisted clockwise to further secure the connection and add compression, providing extra peace of mind.

Versatile & Durable Connection

Safe & Flame-Free Installation

Fast 'No Tools' Installation

Get fast and leak-tight connections first time, every time. Using a unique blend of push-fit and multi-seal technology, Speedfit can be installed and demounted in seconds without the need for tools or hot works.

The fittings work with JG Speedfit pipes, other PEX, CPVC and standard copper pipes. All plastic components are made from non-toxic, corrosion-resistant polymers that also resist scale buildup, ensuring system longevity.

No hot works are required for connections thereby eliminating safety risks and need for permits associated with open flames on job sites. The system includes a wide array of fittings (couplers, elbows, tees, manifolds), valves, and flexible hoses for all parts of a plumbing system.
