Irrigation Fittings Pick & Mix – Buy Exactly What You Need

Real irrigation jobs never need ten of one fitting. A row of pots might need a couple of tees, a few elbows to get round a corner, a handful of joiners and an end plug. So instead of buying packs you'll only half use, pick each fitting and the quantity you need, add them all to your basket and check out once.

How to Order

  1. Choose a fitting from the list.
  2. Set the quantity you need and add it to your basket.
  3. Pick the next fitting, and repeat until your basket matches your job.

What's Available

Size Fittings
4mm (micro drip line) Joiner, elbow, tee, cross, top hat grommet
13mm (main feed line) Joiner, elbow, tee, cross, end plug, top hat grommet
13mm double barb (pumped lines) Joiner, elbow, tee, end plug
Reducers 13mm to 4mm tee and cross, 19mm to 13mm tee, 25mm to 19mm tee

See the Which irrigation fitting? guide in the photos for what each fitting does.

How to Fit

  1. Cut the pipe square with sharp scissors or a pipe cutter.
  2. Dip the pipe end in hot water for a few seconds to soften it.
  3. Push it firmly over the barb until it reaches the shoulder of the fitting.

Top hat grommets are different: drill a hole in the tank or lid, press the grommet in, then push the pipe through.

Use Them For

🌿 Rose's Pro-Tip: lay your system out dry on the floor before you cut anything. It's far easier to see where tees and elbows need to go than to work it out pipe in hand.
