Thetford Valve Connection to waste piping

77 Overlander.
Tried to pull black water outlet off the pipe last weekend per the service manual which indicates that SOME valve to pipe connections that year may be glued. Would appear that mine is one of those.

I have a spare valve which was left in trailer by PO. Appears to right valve but also appears to missing O rings. W/O O rings outlet side of valve does not fit well in to a new 3" long sweep T-Y so am wondering how they glued valve to pipe? Would rather not glue up replacement so w/ O ring do pipe and valve seal correctly?

Also anyone know where to get O rings or best to just buy a whole new valve from Inland RV or anyone else?

Go to a Plumbing supply business...not Lowe's or Home Depo.
The person at the counter will know what you are doing. A digital
camera with a few pic's of the trailer end will help when you go.

If you can't find anything locally, try McMaster-Carr. I know others have found O-rings that worked with even older Thetford valves there.
