PVC Union Pipe Fitting, 4Pcs 1inch Slip Union Coupling Adapter, Schedule 80, EPDM O-ring, Socket x Socket, Grey

Works perfectly! Got them to make a saltwater sump and they fit perfectly. Definitely much cheaper than other places but still excellent quality. I have had zero problems with anything leaking. Super easy to install, just make sure to pvc glue them!

Very good, heavy duty, will buy again

Worked perfectly for replumbing my pool to have a faster drain-down option. Most importantly, having this also allowed me to keep my original plumbing intact with no cutting pipes in case I wanted to just switch back to the original for some reason. All the new connections (to the filter, pump, and this union on the discharge pipe) were screw on/off. Perfect fit on 2" schedule 40 pipe. I have no idea why some are saying it's too big unless they're some kind of non-standard pipe. I also liked how heavy duty these are -- they match the rest of the Jandy pool valves/connections so they look like they're supposed to be there .

Excellent quality and design. Perfect for pool equipment plumbing 2" PVC hose connections. I rebuilt my entire pool plumbing with these unions- not one leak on any hose connections - first time tighten each connections- no leaks. Two Thumbs up!

These unions are excellent. Mich les cost that big box stores too

extremely high quality and extra o rings are a bonus

Good quality, durable, does the job, but more on the expensive side

Absolutely functional, leak-free unions. Buy twice as many as you think you need. They come with gaskets installed plus extra gaskets.

Plumbing a saltwater aquarium and this exactly what I needed and received them in a couple days.

O-rings are good quality and didn't leak. Glued up to my aquarium plumbing very easy. Highly recommended.
