The Hydro-Rain 1/2" Blu-Lock x 1/2" MPT Adapter is the essential component for connecting your 1/2" Blu-Lock Tubing (Swing Pipe) to standard sprinklers or threaded saddles. This fitting transitions from the flexible push-to-connect pipe to a 1/2" Male Pipe Thread (MPT), allowing you to screw directly into most pop-up spray bodies or rotors. Ideal for building custom swing joints, this adapter features a continuous swivel design. This means you can screw the threaded end into a sprinkler head or saddle and then rotate the fitting to any angle without kinking the tubing. It speeds up installation and makes adjusting sprinkler height easy.
As one of our most versatile irrigation fittings, it combines the speed of push-fit technology with the reliability of a stainless steel grip ring.

Follow these steps to connect your sprinkler heads securely.
Step 1: Install the Threaded End
Apply thread seal tape to the 1/2" male threads. Screw the adapter into the bottom of your sprinkler head or into a saddle on your lateral line. Hand-tighten firmly.
Step 2: Prep the Pipe
Cut your 1/2" Blu-Lock tubing cleanly and squarely. Ensure the end is free of dirt or jagged edges.
Step 3: Push to Connect
Insert the tubing end firmly into the Blu-Lock socket until it stops. You will feel it pass the internal grip ring.
Step 4: Verify & Adjust
Pull back gently on the tubing to ensure it is locked. The fitting will swivel around the pipe, allowing you to position the sprinkler head exactly where you need it.
