The Hydro-Rain 1/2" Blu-Lock x 3/4" MPT Adapter is a specialized fitting designed to bridge the gap between flexible 1/2" Blu-Lock Tubing and larger 3/4" threaded components. This is the perfect solution for connecting standard swing pipe to large gear-driven rotors or impact sprinklers that feature a 3/4" inlet. Instead of using multiple bushings or adapters to step up the size, this single unit does it all.
It features the patented Blu-Lock push-to-connect technology on one side and a swiveling 3/4" Male Pipe Thread on the other, ensuring a fast, leak-proof, and flexible connection for your heavy-duty irrigation fittings.
Adapt 1/2" Swing Pipe to 3/4" Threads.

Follow these steps to connect your larger sprinkler heads.
Step 1: Install the Threaded End
Apply thread seal tape to the 3/4" male threads. Screw the adapter into the bottom of your rotor or into a 3/4" PVC fitting. 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.
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 large sprinkler head exactly where you need it.
