Description
The Universal Compression Coupling is designed to connect MDPE pipe to a wide range of other pipe materials, including PVC, ABS, copper, stainless steel, galvanised iron, and lead. With a pre-assembled body and included pipe liner, this versatile fitting simplifies the joining process across mixed material systems. The UTC ends are equipped with stainless steel teeth to ensure a strong mechanical grip and excellent end-load resistance. Suitable for water supply and general low-pressure fluid systems, the coupling offers reliable sealing and quick installation without the need for specialist tools.
Key Features & Benefits
- Multi-Material Compatibility: Connects MDPE to various pipe types, including metal and plastic,c without the need for adaptors.
- Pre-Assembled for Convenience: Supplied ready to install—simply insert the pipe and tighten the nut.
- High Grip Strength: Stainless steel teeth provide strong end-load resistance, preventing pipe pull-out under pressure.
