WaterMark—Equal Tee

John Guest equal tee allows three equal sized pipes to be connected in a push-fit tee configuration. The John Guest equal tee fitting connects all three pipes using push-fit ends for quick and secure installation. The John Guest Speedfit RV Range is purpose built to comply with Australian Standards and carries WaterMark certification for assurance in potable water applications. Engineered for enhanced performance, these fittings are rated to handle increased working temperatures and pressures tested and warranted to operate at 80°C and 1000 kPa. Ideal for use in caravans, RVs, and mobile plumbing systems requiring reliable, high performance push-fit connections.

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.
