Description
This equal tee fitting is designed to connect three pipes of the same diameter, allowing air and pneumatic systems to branch or split flow efficiently. It is commonly used in air ring main installations where a symmetrical layout and balanced distribution are required.
The push-fit connection enables fast, tool-free installation without heat or sealing compounds, significantly reducing installation time compared to traditional jointing methods. A precision-engineered collet locking system grips each pipe securely without deformation or flow restriction, while the integrated nitrile O-ring provides a reliable, airtight seal.
Fully demountable for ease of maintenance, the fitting allows systems to be modified or extended with minimal downtime. Manufactured from tough engineered plastic, it is compatible with John Guest nylon and powder-coated aluminium pipe, as well as a wide range of plastic and soft metal pipe materials.
