The 1/2" Compression Coupling Adapter is a problem-solving fitting designed to connect two different sizes of drip irrigation tubing. Specifically engineered to adapt smaller Raindrip (.620" OD) tubing to standard DripWorks (.700" OD) 1/2" poly tubing, this coupler allows you to extend or repair an existing system without replacing all your old lines.
If you have an older system installed with Raindrip components and want to expand using professional-grade DripWorks parts, this is the essential link you need. As one of our most specific irrigation fittings, it features two distinct compression ends—one sized for .620" OD and the other for .700" OD—ensuring a leak-proof connection that bridges the compatibility gap.
Verify your tubing diameters carefully.

Identify your tubing sizes before starting.
Step 1: Prep the Tubing
Cut both the Raindrip (.620") and DripWorks (.700") tubing ends cleanly and squarely.
Pro Tip: Warm the ends in the sun or hot water to make insertion easier.
Step 2: Connect the Small Side
Identify the side of the coupler designed for .620" tubing (often marked with a green insert or labeled). Push the Raindrip tubing into this end firmly until it passes the internal ring.
Step 3: Connect the Standard Side
Push the DripWorks .700" tubing into the other end of the coupler (often marked with a black insert). Rock it back and forth until seated fully.
Ensure you have the correct mix of tubing:
