Details

Removing an old appliance regularly leaves an open-ended waste pipe coming out of your floor. Unfortunately, an open pipe will vent dangerous, foul-smelling sewer gases directly into your home. Furthermore, if a blockage occurs down the line, wastewater can back up and overflow straight out of that open end. Trying to glue a cap onto the pipe is risky. This is because different brands use slightly varying diameters from 40mm to 43mm. Therefore, standard solvent sockets will often fail to slide on or leak around the rim.

Fortunately, this genuine McAlpine T23U Multifit compression blanking cap resolves these pipe size issues completely. Thanks to its multi-layered rubber gasket, the cap naturally self-adjusts to wrap around any plastic pipe between 40mm and 43mm. Thus, you do not need to know the exact brand of your pipework beforehand. Instead, simply slide the cap onto the raw end and hand-tighten the ridged nut. Consequently, it compresses the internal ring to create an immediate, airtight barrier that locks out leaks without messy glues.
