  • Metal construction Durable body built for everyday workshop pneumatic use.

Benefits

  • Fast repairs; Restore a damaged air line section without replacing the entire run.
  • Easy extensions; Add length to 4mm tubing quickly and keep routing neat.
  • Reliable seal; Secure push-in grip helps reduce leak risk in your compressed-air system.

Extra Information

  • Use clean, round 4mm pneumatic/PU tubing and ensure cuts are square before inserting.
  • Push the tube in fully until it seats, then do a gentle pull-back test to confirm it’s locked.
  • After installation, pressurise slowly and check for leaks using soapy water.

Pro Tip

  • If a tube end is scratched or oval, trim it back and re-cut square—push-in fittings seal best on a clean, undamaged tube end.
