Thetford parts reference
Thetford 641065
Flapper Assembly
641065 is the Thetford part number for the flapper assembly. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 641167 instead
Thetford marks this number with “USE 641167” on its own parts list, which is the manufacturer telling you 641167 is what to order now. That instruction comes from the document, not from us, and not from what sellers happen to call the part.
Current number: 641167
Which parts lists carry this number

What we have not checked
We can show you that 641065 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
