The Unipipe Difference
- Advanced engineering at the core of Unipipe produces a revolution in piping systems. The system allows for rapid installation and for exceptionally secure joints, ensuring the safe transport of air and inert gases.
SIZES 20mm - 90mm
- Aluminium Nut
- Stainless Steel Clamp Ring
- Coloured Identification Ring
- HNBR O-ring
- Machined Aluminium Body
The nut inside the fittings and the unique patented dynamic gripping ring produce such a secure joint; there is no way to separate the pipe from the fittings.
The coloured plastic ring identifies the product and working pressure for each fitting. This innovative fitting is compact and light, making this system one of the most highly rated aluminium systems.
The Unipipe design produces a fitting with exceptionally secure joints that is reliable and more advanced than other aluminium pipe systems on the market.
The innovative engineered design is manufactured with quality materials, and QA destructive tests result in the pipe bursting before the fitting fails.
With simplicity of design, fewer parts and rapid installation. No hassles from compliance with factory-set torque settings.
