To you have a AN or MS number for the correct O-Ring.
Thanks a Million.
I donít have an Usher Gascolator on my RV, so I donít know the proper O-ring size. It looks like Vans sells them however... try here:
That same page offers the replacement screen as well in case you need that.
If you measure the new o-ring carefully (OD, ID and thickness) there is a size chart at Oringsandmore.com that will tell you the numerical size designation.
