How to Choose Drip Fittings

Drip fittings connect and branch your tubing — barbed and compression couplings, tees, elbows, and end caps, plus adapters that step poly tubing down to 1/4 in. distribution line. Match the fitting to your tubing’s outside diameter, since drip tubing comes in several sizes that are not interchangeable.

Barbed fittings push inside the tubing and rely on a tight wall fit; compression fittings grip the outside and hold better under pressure. Keep a few couplings on hand to repair splits without re-running a whole dripline.
