Description

Extend Your Lines. Secure Connections.

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.

Why Choose a Compression Coupler?
  • Seamless Extension: The most efficient way to add length to your 3/4" supply line, allowing you to expand your system as your garden grows.
  • Permanent Repair: Ideal for fixing accidental cuts or kinks in your mainline. Simply cut out the damaged section and bridge the gap with this coupler.
  • Secure Grip: The internal ring bites firmly into the .940" OD tubing, resisting pull-out from pressure surges or thermal expansion.
  • Durable Build: Molded from high-impact ABS plastic with UV inhibitors to withstand years of sun exposure.

How to Install: A Step-by-Step Guide

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.
