Hello, first post.
I need the rubber seal "O" ring that goes between the Thetford valve and the black tank on a stock '77 GMC. The GM Parts Book list p/n 701212, but this brings up nothing online. The O ring mounts on the valve on a 3.5" flange. My valve is fine, just need this O ring as mine is dried out and cracked causing a little drip.
Thanks
Jeremy

Let me think on that one for a while. I bought one once many years ago. I just do not remember where.
You might try calling Thetford direct at:

Fax: 1-734-769-2332
They are in Ann Arbor, MI

Like most items, we stock them.
They are not popular so you'll not find them at RV places.

Well I called Thetford and they told me that the O ring is not a replaceable part and I have to order a new valve!
I looked at the link provided by J.R. but it is all toilet parts, I am working on the Thetford valve on the black tank.
It was suggested that Thetford 09872 repair kit contains the needed O ring, but it seems silly to spend $20 for a bunch of seals I don't need. Oh well.

There seems to be some minor confusion here. Jeremy does not need the closet flange seal, what he needs is the O-ring that seals the Slide-EZ valve to the black tank flange.
Jeremy-
O-rings are specified by the diameter of the "rope" that the are made from and the ID of the circle of that rope. If you to measure the depth of the grove that O-ring goes in, you want one that is about 125% of that depth. I may have a valve in my barn (I don't think so, but I will check next time I am out there)and I would send along the numbers. That may not be right because there were two different valves used for GMC. One is all plastic and the older has a stainless cover on the tank side.
Do not even bother contacting Thetford (or if you do don't expect much). In my recent dealings with the company, I was very impressed by the complete and total lack on anything like customer service and support. Even with part numbers in hand (I am in striking range) I could not talk to anybody directly, I had to work though a telephone maze and I finally got an order placed. (That was a mistake.) When no parts arrived, I called back hoping to get a tracking number and was told that if you were not a standing client, they would always wait 3 days before they pulled the order for shipment. This was day 4 and it had not left yet. I cancelled the order and drove 30 miles to a shop that did have the parts in stock.
I really wanted to change the tank to a Valterra valve (way cheaper and more available and part are on a pin at the local places), but the bolt holes are all wrong and may first attempt at an adapter failed. When I come up for air, maybe I will try again.

WE are a dealer for ALL RV suppliers and have access to parts as long as it
is available.
We spend time to supply people for a two dollar part, Unlike the others.
That's why we became the largest supplier.
Also knowledgeable about RV and GMC MH
