AirCraft Closing Plug PU 4mm
At a Glance: Push-in blanking plug to seal unused 4mm PU tube ports
The AirCraft SG APP04 Closing Plug PU 4mm is the simple, essential little part that stops small leaks from becoming big frustrations. It’s designed to blank off unused push-in pneumatic ports that accept 4mm polyurethane (PU) tubing—perfect for manifolds, distribution blocks, spare outlets and temporary line changes. Push it in, seal the port, and keep your compressed air system tidy and efficient.
Closing plugs are ideal when your pneumatic layout changes over time or when equipment has optional ports you’re not using. The SG APP04 gives you a fast way to close a 4mm push-fit opening without redesigning the whole setup.
