Fernco Drain Coupling - 180mm to 195mm

This coupling is designed to connect two plain-ended pipes with the same or similar outside diameters, including materials like clay, concrete, plastic, and cast iron commonly used in drainage.

No, this coupling is specifically designed for drainage applications and is not intended for potable water systems.

You will need a nut driver and a calibrated torque wrench to properly tighten the stainless steel clamps for a secure seal.

The coupling is designed for pipes with the same or very similar outside diameters. Refer to the specific product size range for compatibility. If in doubt, measure the outside diameter of both pipes.

While primarily designed for underground drainage, it can be used for above-ground applications where a secure, sealed connection is required for pipes of similar outside diameters, provided it's protected from excessive UV exposure or extreme conditions.

Unadopted drainage refers to private drainage systems that are not maintained by the local water authority. This coupling is a tested and reliable option for such systems.

EPDM rubber is known for its durability and resistance to weathering, ozone, and common drainage fluids, offering a long service life when used within its intended application.

Verify that the pipes have similar outside diameters and are fully inserted. Re-tighten the stainless steel clamps using a torque wrench to the manufacturer's recommended setting. Ensure the pipe ends are clean and free of obstructions.

Ensure the pipe ends are smooth and free of burrs. Lightly moistening the pipe ends or the inside of the coupling with water may help. Confirm the pipe's outside diameter is within the specified range for the coupling.

Check that the correct size coupling is being used for the pipes. Ensure the clamp screws are not stripped and that the threads are clear. If the clamp is fully tightened and still loose, the pipe diameter may be too small for the coupling.
