Details

When repairing a broken bathroom pipe or extending a waste line during a new sink installation, you often run into a frustrating roadblock: different pipe manufacturers use slightly different outer diameters. Trying to join an older 32mm pipe to a modern 34mm or 36mm pipe using standard push-fit or solvent couplers is impossible—the fittings either won’t slip on or they leave a loose gap that causes destructive water leaks inside your floorboards or vanity cabinets.

This McAlpine Multi-Fit Straight Coupling eliminates all the guesswork and frustration. Because it features independent, universal compression collars on both ends, it compresses down uniformly onto any 32mm to 36mm plastic or copper pipe regardless of the brand. There is no messy glue required and no need to hunt down specific pipe sizes—just insert the pipes and twist the collars by hand for an immediate, professional, and watertight repair.

Instructions

1. Simply slide the white nut over the pipe first along with the nylon washer, before the pointed black rubber washer
2. Make sure that the black rubber washer is pointing the thin end towards the white fitting you have yet to put on and slide the rubber on an inch or so
3. Push the rest of the fitting on so that the rubber joins up with the plastic fitting, you may then try and push the fitting with the rubber further down the pipe if need be
4. Finally bring the nut back and screw onto the rest of the fitting, compressing the pointed washer against the plastic to make a seal, then repeat the action for the other side and that’s it!
