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!

For thicker waste pipes such as iron or smaller diameter pipes the plastic insert may have to be carefully cut out in order to install

Details

Joining different types of waste pipe—or finding a fitting that accommodates pipes that are slightly non-standard in diameter—is a common plumbing headache. Attempting to force a rigid fitting onto an iron or older copper pipe often leads to cracked seals or leaks. Furthermore, when working on high-use areas like public urinals or commercial sinks, you need a fitting that is both robust and easy to disconnect for routine maintenance. The wrong choice can lead to a messy, time-consuming job that requires constant repair.

The McAlpine V15M solves these issues by providing a flexible compression fit that adapts to the pipe rather than forcing it. Its “Multifit” technology handles the 50mm–55mm range perfectly, and the compression seal is highly reliable. The installation process is straightforward, requiring no tools, which simplifies your workflow significantly. Whether you are dealing with modern plastic pipework or older metal systems, this tee junction ensures a secure, leak-free connection that can be easily accessed when maintenance is needed.
