The John Guest brass straight male thread connector designed to join tubing to a female threaded port. This straight adaptor features a durable brass male thread combined with a reliable push-fit connection for quick and secure installation. Ideal for use in water, air, and pneumatic systems, it provides a robust transition between threaded components and tubing. Compatible with a range of tubing materials and suitable for both residential and commercial applications.

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.
