Fernco PlumbQwik Straight Coupling - 37-45mm

The Fernco PlumbQwik Straight Coupling can connect pipes made of various materials including PVC, ABS, copper, steel, and cast iron, as long as their outer diameter falls within the 37mm to 45mm range.

No, this coupling is designed for low-pressure, above-ground waste and grey water drainage only. It is not suitable for pressurized systems or potable water lines.

No, installation is straightforward. You only need a standard screwdriver or nut driver to tighten the two clamp bands.

This coupling is intended for above-ground applications. For underground use, Fernco offers different product ranges designed for those specific conditions.

The connection is designed to be secure and long-lasting for its intended use. However, it is also removable and refittable, allowing for adjustments or replacement if needed.

The coupling is designed to fit pipes with an outer diameter ranging from 37mm up to 45mm.

Ensure the clamp bands are tightened evenly and sufficiently. Check that the pipe ends are clean and the coupling is correctly centered over the joint. Verify that the pipes are within the specified 37-45mm diameter range.

Make sure the pipe ends are smooth and free of burrs. Slightly loosen the clamp bands if they are still attached from a previous fitting. Ensure the pipes are not excessively deformed.

The pipe may be slightly undersized for the coupling's range, or the pipe material might be compressible. Tighten the clamp bands further if possible. Ensure you are using the correct size coupling for your pipes.
