The 3/4" Compression Coupler is the standard fitting for connecting two pieces of 3/4" poly tubing together. Whether you are extending a mainline run to reach a new garden bed or repairing a cut in your existing system, this coupler provides a fast, permanent solution.
Engineered for high-flow applications, this fitting features heavy-duty internal compression rings designed to grip the larger .940" OD tubing. As one of our most reliable irrigation fittings, it creates a leak-proof seal that withstands the pressures of large residential and commercial systems without the need for glue or clamps.
Verify tubing dimensions before purchasing.

Installation requires force but no tools.
Step 1: Prep the Tubing
Cut your 3/4" poly tubing squarely at the connection point.
Important Tip: 3/4" tubing is stiff. Allow the ends to warm in the sun or dip them in hot water for 10-20 seconds to soften the plastic before installing.
Step 2: Insert First Side
Push the first tube into one end of the coupler. Rock the tubing back and forth while pushing firmly until it passes the internal resistance ring (approx. 3/4" deep).
Step 3: Connect Second Side
Repeat the process for the second piece of tubing to complete the connection.
Ensure this coupler fits your system:
