Plastic Shut off Valve

A 12mm in-line push-fit valve designed to quickly and safely isolate a fixture or appliance. Featuring an integrated 1/4 turn isolation mechanism, it provides reliable flow control in water, air, or fluid systems. Made from durable plastic, this valve installs easily without tools and connects directly to 12mm plastic or soft metal tubing.
John Guest push-fit fittings provide a quick and reliable solution for creating airtight connections without the need for tools, heat, or sealants. Ideal for potable water systems in RVs, caravans, boats, and residential setups, these fittings streamline installation and significantly reduce setup time compared to traditional methods. The fittings use a unique collet locking mechanism that securely holds the pipe in place without damaging it or restricting flow. They can also be easily disconnected and reused, making them well-suited for systems requiring routine maintenance or future modification. Constructed from robust acetal copolymer and featuring a nitrile O-ring, the fittings are compatible with a variety of tubing materials, including nylon, LLDPE, powder-coated aluminium, copper, and PEXa. All fittings are manufactured and assembled in the UK, and are suitable for use in industrial, commercial, and food-grade applications.
