The Primaflow 40mm compression waste straight connector is an essential component for DIY enthusiasts and plumbing professionals looking to join two lengths of 40mm waste pipe without the need for messy solvent welding. It offers a secure, reliable connection through a proven nut and olive mechanism, making it perfect for quick repairs or new installations in domestic waste systems. While it provides an excellent mechanical seal, users should ensure the pipe ends are cut square and deburred to prevent leaks before tightening the compression nuts.

Ensure the pipe is inserted fully past the olive and the nut is tightened securely. Check that the pipe end is free of burrs or scratches.
Check that the threads are aligned correctly. If the nut is cross-threaded, unscrew it completely, realign, and attempt to hand-tighten again.
To install the connector, slide the compression nut and olive over the end of the pipe, then insert the pipe fully into the connector body. Tighten the nut by hand until firm, then add a final quarter-turn with a wrench. Ensure the pipe is cut cleanly and all burrs are removed from the edge to avoid damaging the olive. For care, periodically check for signs of moisture around the nut; if a leak occurs, simply tighten the nut slightly further. This connector is compatible with standard plastic waste pipes manufactured to BS1455/BS1453 standards. Always ensure the pipe is pushed past the internal stop within the connector for a secure grip.
