The McAlpine RWM1 Multifit Rubber Olive is a plumbing fitting designed to provide a watertight seal between a waste pipe and a variety of different fittings, such as traps and soil pipes. The rubber olive is designed to be flexible and stretchable, allowing it to fit snugly around the waste pipe and create a secure seal. The multifit feature of the rubber olive means that it can be used with a range of different waste pipe materials, including plastic, copper, and lead. To install the McAlpine RWM1 Multifit Rubber Olive, simply slip the rubber olive over the end of the waste pipe, ensuring that it fits tightly and snugly. The fitting or trap can then be pushed onto the waste pipe and tightened to create a watertight seal.
