John Guest Ring Main System

Make Reliable Connections the Fast and Simple Way John Guest’s range of air and pneumatic push-fit fittings and pipes are designed to ensure quick and easy installation while guaranteeing airtight pipe connections. Their fittings are available in sizes ranging from 3 to 28 mm and are sturdy enough to meet the demands of small to mid-size applications such as garages and other commercial air piping systems. What sets John Guest apart is their rapid assembly process that eliminates the need for tools, threaded pipes, solvent and glue. With a simple push-fit action, their unique collet locking design firmly and securely holds the pipe in place without deforming it or restricting flow. This feature makes their air systems easy to extend or alter and reduces maintenance and production downtime as fittings are fully demountable without using tools. John Guest’s fittings are available in rigid engineered plastic or brass. They also offer a unique water trap that removes moisture from the airline to improve system performance and longevity. Their versatile solution is designed to work with nylon, powder-coated aluminium pipe, or LLDPE pipe, and it is also compatible with copper, PEXa, and other soft metal pipes.
