Fix a cut micro tube in a minute, and it'll stay fixed.

Micro tube gets nicked by strimmers, chewed by animals or cut too short. This joiner clamps both ends of 4mm tube with compression nuts, so the repair doesn't slip off the way a push-in joiner can.

Why anti-leak?

  • Compression nut clamps the tube, so it won't slip off like a push-on fitting.
  • Hand-tight, no tools.
  • Undo it to move or reuse it.
  • Fits Hozelock, Claber, Gardena and Rain Bird 4mm tube.

DESCRIPTION

Micro tube gets nicked by strimmers, chewed by animals or cut too short. This joiner clamps both ends of 4mm tube with compression nuts, so the repair doesn't slip off the way a push-in joiner can.

Specifications

  • Type: straight joiner, 4mm both ends.
  • Tube: 4mm micro tube, including Hozelock, Claber, Gardena and Rain Bird 4mm tube.
  • Anti-leak: a compression nut clamps each end of the tube.

Fitting

Trim both ends of the tube square. Unscrew a nut and slide it over the end of the tube, push the tube fully onto the barb and screw the nut down hand-tight. Repeat on the other side.

Work perfectly and do much better than the traditional joiners.

FAQ's

How do I repair a cut micro tube?

Trim both ends square, slide a nut onto each end, push the tube fully onto the barbs and tighten the nuts by hand.

Will it fit my 4mm micro tube?

Yes. It fits standard 4mm micro tube, including Hozelock, Claber, Gardena and Rain Bird. Cut the tube square first so it seats fully on the barb.

Can I undo it later?

Yes. Unscrew the nuts and pull the tube off. The joiner can be reused.
