John Guest Speedfit products offer a reliable leak-proof connection with push-fit and multi-seal technology, requiring no tools for simple installation or demounting. This makes maneuvering in tight spaces and readjusting joins easy. Speedfit provides a wide selection of fittings, including plastic, brass, and chrome options, along with tap connectors, valves, and flexi hoses to complete any plumbing and heating job efficiently. When combined with plastic push-fit pipe, these products create a highly flexible plumbing and heating system. All products are accredited by leading testing and approval organizations, including WRAS, and are suitable for use with both plastic and copper pipes. This push-fit plastic fitting is designed for connecting plastic and copper pipes to a cold water tank. To install, simply push the fitting fully onto the pipe and hand-tighten the connector to the tank. For demounting, push the collet towards the fitting body and pull the pipe to release. This fitting facilitates an easier working environment in confined spaces, eliminating the need for hot works on-site. It is suitable for cold water tanks only, with a maximum tank wall thickness of 4mm. The product boasts BS EN 7291 parts 1, 2, 3 and S, WRAS approval, secure and easy demounting without tools, and a 50-year guarantee. It operates within a temperature range of -20 degC to 105 degC, with a maximum operating pressure of 12 BAR at minimum temperature and 3 BAR at maximum temperature. Designed, manufactured, and assembled in the UK, it offers instant push-fit connection, installation, and demounting in seconds without tools, and a safe, flame-free installation process without glue or flux. The Grip & Seal collet features stainless steel teeth and a main O-Ring seal, providing resistance to corrosion and scale build-up. It is compatible with Speedfit PEX and polybutylene plastic pipe (inserts required) and copper pipe.
