John Guest Speedfit products offer a reliable leak-proof connection using push-fit and multi-seal technology. These fittings are simple to install, requiring no tools for mounting or demounting, which is ideal for tight spaces or adjusting connections. Speedfit provides a wide range of plastic, brass, and chrome fittings, tap connectors, valves, and flexi hoses for plumbing and heating systems. When used with plastic push-fit pipe, these products enable a highly flexible system. All fittings are WRAS approved and suitable for use with plastic or copper pipe. Installation involves pushing the fitting onto the pipe and twisting the plastic nut clockwise to secure it. Demounting is achieved by unlocking the nut, pushing the collet towards the fitting body, and pulling the pipe. This system simplifies working in confined areas and eliminates the need for hot works. The connectors are suitable for hot and cold water services, central heating systems, and combi systems. They are BS EN 7291 parts 1, 2, 3 and S, WRAS approved. The fittings offer secure and easy demounting without tools and come with a 50-year guarantee. They operate 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.
