Hey Philip, welcome back and thanks for the picture! Based on seeing that the correct part you are looking for is the Valterra RV Sewer Slip Hub with Flange part # T1005. What RV is this going on?

To install this you'll also ABS solvent cement which we have as part # A05-0303.

Jameson C. Thanks for the response and getting me started. I am probably going to order the LaSalle Bristol RV Waste Valve with 15" to 3" lug #34466N7A. Is the "slip hub" on this waste valve the same as the slip valve you mentioned above? The rig I have is old. A 2003 Kodiak Motor Home built in Canada. I tried adding a photo to this reply but it wouldn't attach. Philip Hoefer

@PhilipH yes it is the same configuration. I wish we could upload pictures in comments but we are still waiting on that. Glad to help though!
