Easy install and doesn’t leak
I installed it my Roadtrek camper. Very easy to install. Just removed the old one and pushed it on the pipe ends. Installed it in May 2025 and still works great. No leaks.

Great product
I love these quick connect adapters. These proved to be harder than the previous ones I used but I managed to expand it.

Very easy to install with a bunch of expensive tools.
These things are amazing for quick repairs. I fixed a broken female adapter in a RV in under 5 minutes. All you have to do is make sure the PEX pipe is cut square and then put the little black insert into the pipe. Push the adapter on the pipe and install the black clip. Very easy and it did not leak. I would use caution about installing one where it could do a lot of damage if it failed (I just don't have any experience with how long they last). But for an RV setting, it works. No need to buy an expensive crimper for adapters that use copper rings. Suggestion: Make sure you buy a plastic PEX pipe cutter. I happened to have one which made a nice square cut.

Does not fit RV tubing like suggested
This is for half inch inside diameter tubing, not the popular gray half inch outside diameter RV tubing. Did I not read close enough? Maybe. But RV plumbing was mentioned. I would buy two of these if they fit. Returned.
