Can I use a pvc compression fitting on pvc pipe?

Answer 1

There are compression couplings designed specifically for PVC pipe. You can find them at any good hardware store, usually in the irrigation material area. It is a tube with a nut on each end and rubber seals that compress against the pipe. Large ones can be found in sizes up to 4" at plumbing supply houses or landscaping irrigation centers. If this is something under pressure, special care must be taken to assure the pipe cannot be forced out of the coupling. This is done by careful blocking or strapping of the pipe. In no case should the coupling be used inside a wall where it cannot be accessed if necessary.

Good Luck!

Answer 2

A brass compression fitting will work on pvc pipe. But if your working with pvc just buy a short peice of pvc pipe and 2 couplers and splice it back together. All that will probably cost less than a compression fitting

Answer 3

Yes you dan use a compression fitting. But you need to have a brass or copper insert in the end of the pipe to give the ring something to compress against without collapsing the pipe.

Answer 4

You can also use brass compression fittings on PVC pipe, as long as you use a Delrin, (plastic), ferrule under the compression nut. Just replace the brass ferrule with the plastic unit and it will tighten down fine. Done it many times.

Answer 5

Depending on the size of pipe, check out a "Tiger coupling". Just slip the pipe inside, and forget it! You can remove it with a removal tool, in case you want to add a pipe later.

Answer 6

As long as it fits the pipe. Do not install any compression fitting where it is not in view (behind walls etc).
