Push-Fit Socket Plug 40mm Black.

This waste system with a push-fit ring seal system is made of polypropylene and is quick and easy to install. Most conventional waste pipe sizes are accommodated (excluding solvent weld waste). For the expansion of pipes and fittings in each socket of push-fit systems, all push-fit joints must have a 10mm expansion gap. Solvent welding and tightening are not required.
