4" PVC Pipe Coupling Adapter Pipe Fittings (Socket x Socket) Contractor Pack Schedule 40 Heavy Duty 4 Inch PVC Slip Socket Connectors for DIY PVC Shelf Garden Support Structure, White

Used them on a orchard sprinkler system worked great

Connected smaller pieces together.

Connectors were perfect.

glued and fit just fine

Used to replace some pool plumbing after getting a new pump & filter. Easy to install following standard PVC practices and was perfect for the 1.5" sch40 pipe I picked up locally. No leaks and doing well under pressure.

Well made, and if my unlabeled pipes had been Schedule 40 it would have been great - but apparently they are NOT 40, so returned this and ordered one that reviewers were complaining was too small, but worked for me.

We have many PVC pipes in our home and in the outside environment. We also have a hard clay soil and as a result we have a lot of problems especially in droughts! The house is on pier and beam so there’s the problem of shifting! We keep a supply of fittings on hand as we live in the country and are DIU

These are actually 3/4 inch fittings. Not like the 1/2 inch elbows I got from China the other day. Because where you buy what. Entirely Satisfied with the product I received today.

Good value delivered to my door , I was in a remote setting and my local hardware store didn’t have what I needed , so within acouple days this was delivered to my door,
