Say Goodbye to Glue and Clamps
Smooth sailing ahead with Blu-Lock fittings!
Our innovative push-to-connect design creates secure, leak-free connections in seconds. Just push your HDPE pipe into the fitting and feel it lock into place—no waiting for glue to dry, no fumbling with clamps.
How Blu-Lock works
The science behind the simplicity:
- Stainless steel teeth grip firmly to your pipe
- Specialized EDPM seal creates a perfect watertight connection
- Rotating capability for perfect sprinkler positioning
Installation in 3 easy steps
Cut
Cut your HDPE pipe straight with pipe cutters
Push
Push pipe into the fitting until it stops, about 1 inch.
Test
Test by gently pulling back to confirm secure connection
Change your mind? No Problem!
Made a mistake or need to redesign part of your system? Blu-Lock fittings aren't a one-shot commitment.
- 1/2" fittings have a built-in release collar — just press down on the collar and pull the pipe free.
- 3/4" and 1" fittings use a separate release tool to disconnect — insert the tool, press to release the internal teeth, and pull the pipe free.
Either way, there's no cutting and no wasted parts. Disconnect cleanly, reposition sprinkler heads as your landscaping needs change, and reuse fittings elsewhere in your system as your layout evolves.
Blu-Lock fittings work with 100 PSI SIDR 15 and 80 PSI utility HDPE pipe in valve-to-sprinkler connections. These fittings are specifically designed for lateral line connections, from valves to heads or drip manifolds.
For mainline or constant pressure applications, check out our PVC-Lock fittings instead.

It fits the system but just today it started coming loose at the blue end and squirting water everywhere. I’m annoyed, it’s a brand new part and it’s not tightly affixed to itself. I’m starting to think I should have gone with a different brand.

Ordered a replacement part and they shipped the wrong Orbit product. I then called their parts department and they hung up over 5 times. I then called their customer service department and they picked up and Cruz who claimed to be the supervisor said he would handle it. 2 weeks later no part has been shipped and they have not issued a refund. This company is thieves/criminals. I have emailed their CEO without response, clearly he is disconnected from his companies criminal day to day operations.
Thank you for letting us know about your experience with receiving the wrong product and getting help from our support team. We will be taking a further look into your conversations to see how we can improve for the future, and someone from our Customer Care team will be following up with you about your order.

This flexible piping made adding additional sprinkler zones a breeze. Very easy to handle, it reduces the required number of fittings and routing around obstacles is a breeze.
Something to note... it lengthens in the hot sun. A 100' length shrank about 5"-6" when cold water was run through it after sitting in the sun before being buried. This cause some added stress on a few fittings. I was able to alleviate the tension on the fittings by digging the inside corners of the trenches with a bit sharper curve. Had I realized ahead of time, I'd have accommodated the issue by cutting the flex piping a little longer between fittings. At least 1" added every 20'.

The Orbit system is simply the best!

I searched high and low for this part and finally found it to repair my sprinkler system. I ordered 2 so I'll have a spare one on hand.

Working well with existing Blu lock system!

The Blue-lok coupling worked where others didn't. It was exactly what I needed, was easy to order, and was delivered quickly. Thank you Orbit.
You'll sell a lot more of these if you put them on store shelves with all the other irrigation parts. It could also save people from the frustration and aggravation of buying parts that don't work.

The quality of the accessories is excellent; my irrigation system is the envy of all the neighbors because there are no dead spots.

I love the Blu-Lock fittings. I just wish they were more readily available at local stores. I would highly recommend these for anyone installing irrigation lines.
I would request availability of 1 1/2" reducers as many people use irrigation pumps that discharge 1 1/2". That would make installation of complete systems possible using only Blu-Lock fittings.

I just wish I can go to Lowe’s and buy it otherwise it works great

Took a while to figure out how to attach the new item to the existing PVC pipe. But all is well now and the irrigation system is once again working. Thank--John
