AirCraft Closing Plug PU 12mm
At a Glance: Push-in blanking plug to seal unused 12mm PU tube ports
The AirCraft SG APP12 Closing Plug PU 12mm is the fast, tidy way to close off unused pneumatic ports so your compressed air system stays efficient and leak-free. Designed to blank off push-in fittings/ports that accept 12mm 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 workshop or machine air setup running cleanly.
Pneumatic installations often evolve—extra ports get added, lines get rerouted, and sometimes you simply need to isolate a section for maintenance. The SG APP12 lets you close a 12mm push-fit opening quickly without extra adaptors or complicated plumbing.
