Propane tank oring

[Slacker]

Howdy to all,
I lost the oring/gasket that fits in the fill fitting on an ASME tank on my 2003 BT. Anybody know who would have them or the dimensions?
Thanks.

That part is a 1-3/4" ACME LP FILL VALVE GASKET

RV dealers should have them, ebay, or a nice 3 pack with reasonable shipping can be found here:

I recommend getting an extra fill valve dust cap as well. That's where I store my extra gaskets.

Thanks LTL, greatly appreciated!
