Monument 138R Socket Forming Tool (15 & 22mm) 138R

The Monument 138R is a socket forming tool used to join two pieces of copper pipe of equal diameter without needing traditional fittings, cutting down on material costs and time. It works with both 15mm and 22mm copper pipe, with wall thicknesses of 0.7mm and 0.9mm respectively, covering common sizes used in UK plumbing.

The tool features a loose former design, making it easier to withdraw after forming the socket without damaging the joint. The resulting capillary joint can then be finished with either soft or hard soldering, depending on the application. It suits domestic plumbing tasks such as repairs and installations where space is tight or standard fittings are impractical.
