The Hydro-Rain 1/2" Blu-Lock Coupler is the easiest way to join two pieces of 1/2" Blu-Lock Tubing (Swing Pipe). Whether you are extending a lateral line to reach a distant spray body or repairing a cut in your swing joint assembly, this fitting provides an instant, watertight connection. Unlike traditional barb fittings that require strenuous insertion force, the Blu-Lock coupler slides on smoothly and locks automatically.
It is one of our most user-friendly irrigation fittings, featuring built-in release tabs that allow you to unlock and remove the tubing without any special tools—perfect for making adjustments on the fly.

Follow these steps to join two sections of swing pipe.
Step 1: Prep the Pipe
Cut both ends of your 1/2" Blu-Lock tubing cleanly and squarely. Ensure the ends are free of dirt or mud.
Step 2: Push to Connect
Insert the first tube into the coupler until it hits the internal stop. You will feel it click past the grip ring.
Step 3: Connect the Second Pipe
Repeat the process for the second tube on the other side of the coupler.
Step 4: Verify
Pull back gently on both sides to ensure the connection is secure. If you need to remove it, simply press the release tabs on the collar and pull the tubing out.
