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!

Nice unions! Don't leak. Comes with additional gaskets. Easy to install. Easy to get apart if needed. A nice size too. Seems to be well made. I am happy with it for the price you can't beat it. Just make sure you have the screw part of it on your pipe before you glue it or you can't get it on there. Glad I bought these.

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 .

Product arrived quickly and as described.

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

Used these to join the flex pvc pipe from my pool pump to the sand filter, for ease of installing and then disconnecting for winter. Perfect fit for the 1 1/2 in pipes. I used oatey rain & shine to attach to the pipes and it works great. No leaks around the pipe connections and no leaks from the union. it's only been about a week so I can't speak to durability yet, but the unions are heavy duty and appear like they will last. I'll update at the end of the summer or sooner, if any problems. They do come with two extra gaskets, so that's also a plus.

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

Great price and it includes 2 EXTRA O rings. Worked great for my rain tank installation.

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.
