Thetford 619845
Flapper Assy-Double Pole/White
619845 is the Thetford part number for the flapper assy-double pole/white. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 623887 instead
Thetford marks this number with “USE 623887” on its own parts list, which is the manufacturer telling you 623887 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: 623887
Which parts lists carry this number
It appears on the parts list for the 1200 Series.

What we have not checked
We can show you that 619845 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 That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
