The Hydro-Rain 3/4" Blu-Lock Coupler is the fastest way to join two pieces of 3/4" Blu-Lock Tubing together. Whether you are extending a lateral line to reach a new zone or repairing a damaged pipe in a wet trench, this fitting gets the job done in seconds.
Unlike PVC repairs that require dry conditions, primer, and cure time, the Blu-Lock coupler works immediately—even in wet environments. The "Push-and-Go" technology creates a permanent, leak-proof seal instantly, allowing you to pressurize the system right away and move on to the next job.
Understanding compatibility is key. This fitting connects two pieces of lateral pipe.

Follow these steps to join two pipes securely.
Step 1: Prep the Pipe
Cut both ends of your 3/4" Blu-Lock tubing cleanly and squarely. For the best connection, use a beveling tool to chamfer the outside edges, ensuring they slide in smoothly.
Step 2: Push to Connect
Insert the first tube into the coupler until it stops. You will feel it pass the internal grip ring.
Step 3: Connect the Second Pipe
Push the second piece of tubing into the other side of the coupler until fully seated.
Step 4: Verify
Pull back gently on both sides to ensure the stainless steel teeth have locked onto the pipe.
This fitting is specifically designed for Blu-Lock Lateral Pipe:
