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.

Quick blanking solution for clean, leak-resistant pneumatic setups

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.

Extra Information

  • Ideal for spare ports on manifolds, distribution blocks, regulators and pneumatic accessories.
  • For best sealing, ensure the port is clean and free of debris before inserting the plug.

Pro Tip

  • Keep a few closing plugs in your toolbox—when you remove a line for diagnostics, blank the port immediately to prevent leaks and keep dust out of the system.

Features

  • Push-in fitment Installs quickly into compatible 4mm push-fit ports.
  • 4mm size Suits pneumatic ports designed for 4mm PU tubing.
  • Compact design Neat, low-profile plug for tight installations.
  • Practical service part Great for temporary blanks during maintenance or reconfiguration.

Benefits

  • Stops Air Leaks: Seals off unused ports to reduce wasted air and pressure drop.
  • Tidier Installations: Keeps manifolds and air lines neat and organised.
  • Faster Changes: Makes it easy to blank a port during upgrades or troubleshooting.

Safety

  • Always depressurise the air system before inserting or removing pneumatic plugs and fittings.
  • Wear eye protection when working with compressed air lines.
  • Check the system for leaks after installation before returning equipment to service.
  • Do not use damaged plugs or contaminated ports, as it may prevent a proper seal.
