Wide-Range Coupling
Coupling for connecting pipes made of different materials (steel, cast iron, ductile cast iron, asbestos cement, PVC, PE-HD/PEX).
- Housing and follower ring made of steel
- Rilsan corrosion protection (min. 250 µm according to GSK)
- Screws and nuts galvanized/sheraplex-coated or made of stainless steel
- Seal material EPDM
- Diameter tolerance max. 17 mm
- Pipes can be angled by max. 6 degrees
- Temperature Range: -20 °C - +30 °C
Note:
When used on PE-HD/PEX pipes, our inner support liner SHVA is required. Alternatively, we recommend restrained products such as FRIASAFE or FRIAGRIP.
