Check the version before you order
This part comes in more than one version, and they differ by colour. Ordering the wrong one gets you a part that is real, correct for the model, and still not the one you need. The other versions on the same documentation are listed below — check yours before ordering.
Availability
Thetford marks this number with an asterisk, and the legend on that document reads “LIMITED AVAILABILITY”. It is still a live number, but supply is constrained, so it is worth checking secondary sources rather than assuming it is freely stocked.

What we have not checked
We can show you that 631359 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 That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
