FloPlast Flofit+ Push Fit Reducing Coupling - 22mm x 15mm

Reducing couplings are a push fit coupling that is used to decrease the diameter of a straight pipe run by connecting two different diameter pipe lengths together. Like all other push fit plumbing fittings, they can be installed, removed, and re-used with ease by simply inserting a pipe into them while using a pipe insert and twisting the plastic nut to lock it in place, then untwisting it if the pipe needs to be removed.
