PU Push on Closing Plug

Closing Plug PU is the quick, tidy fix for unused pneumatic ports that would otherwise leak air or collect dust. Designed to blank off push-in fittings/ports that accept 6mm polyurethane (PU) tubing, it’s ideal for manifolds, distribution blocks, spare outlets and temporary line changes. Push it in, seal the port, and keep your compressed air system efficient and workshop-ready.
