NDS U-0750-S PVC Pipe Fitting, 3/4-Inch Slip Union, Schedule 80, EPDM O-ring, Gray

Makes for easier replacement of valves or sections of sprinkler system. I have several on sprinkler valves that have been connected for 17 plus years and are not leaking.

For sprinklers

Sealed properly for the piping I was working on . Its low quality so do not expect it to be on the same level of spears etc but it does do its job.

I bought three of these and like several other reviewers, had an issue with one in which the coupler wouldn't slide onto a piece of PVC pipe because the sizing was not precise. I was able to fix the issue by doing a little sanding on the end of the pipe until it was small enough to slide into the union, but the quality control on this product is a little shoddy. For the price they're a great deal, but you may have a little extra work ahead of you to actually get them to work. Once glued onto the pipe and in place, they're great! No leaks and easy to loosen for maintenance.

No issues with the union. Just like the big box stores but a little bit cheaper.

KBI products quality is superb. The only problem is sourcing the product(s) due to box stores and supply houses selling poorly made off-shore products. I wait for mine through on-line shopping usually.

Excellent PVC unions

Needed these for a filtration/softener system, could not find locally. Good quality schedule 80 fittings
