12mm Tube Insert

Creates a rigid connection when fitting pipework into a John Guest fitting for potable liquid or hot water applications John Guest pipe inserts play a vital role in providing extra support to pipework, ensuring that the ends of the pipe are kept nice and round, and minimising any loss of shape that can occur when cutting
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.
