The 1/2" Compression Coupler is the essential utility player in your drip system toolkit. Designed to join two pieces of 1/2" poly tubing in a straight line, it is perfect for extending a run to reach new plants or quickly repairing a cut in your mainline.
Like other reliable irrigation fittings in the compression series, this coupler uses a secure friction-fit design. The internal metal ring grips the tubing tightly once inserted, creating a permanent, watertight seal without the need for glues or clamps. It is a cost-effective solution for permanent installations where a low-profile connection is desired.

Install your coupler securely with the "Rock and Push" method.
Step 1: Prepare the Tubing
Cut your 1/2" poly tubing cleanly and squarely. If repairing a line, cut out the damaged section entirely.
Step 2: Warm the Ends (Recommended)
Compression fittings are designed to be tight. To make installation easier, dip the end of the tubing in warm water or let it sit in the sun to soften the plastic.
Step 3: Push and Rock
Insert one end of the tubing into the coupler. Push firmly while "rocking" the tubing back and forth (up and down) to work it past the internal compression ring. It should insert about 1/2" to 3/4".
Step 4: Connect the Other Side
Repeat the process for the second piece of tubing to complete the connection.
