Sealing threaded connection on PVC piping

Sealing threaded connection on PVC piping

Sealing threaded connection on PVC piping

(OP)
We have several joints that constantly leak. The piping is sch 80 PVC and the liquid is sodium hypochlorite. Has anyone found a thread sealant that works better than others? We cannot glue/weld this joint due to its configuration. Teflon tape is just not doing the trick. Any suggestions?

RE: Sealing threaded connection on PVC piping

You can try Permatex FORM-A-GASKET No. 2 Sealant. It can be used on PVC.

I have not had any luck with Teflon TAPE but have very good luck with a white paste with Teflon. Don't try to use both.

Note that you should not use pipe dope as it degrades the PVC.
