Description
This U-bend fitting is designed to connect two equal-sized pipes to form a compact U-shaped bend within compressed air and pneumatic systems. It is ideal for space-restricted installations, return loops or situations where pipework needs to be redirected efficiently without increasing system complexity.
The push-fit design enables fast, tool-free installation without the need for heat or sealing compounds, helping to reduce installation time compared to traditional jointing methods. A precision-engineered collet locking system grips the 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 air pipe, as well as a wide range of plastic and soft metal pipe materials.
