I have what I believe is the standard original gascolator, upside down glass bowl. Does anyone know the size and or source for a replacement rubber gasket?

I have got them from Aircraft Spruce. May have some in my stash. If I do, I’ll get the part number for you when I go back to the hangar..

I think this one is what you need, but I'm going from memory. Measure the OD of the glass and make sure the gasket is no smaller.

(Choices are 2", 2-1/8" and 2-1/4")

The Spruce part number I have is 05-11189. It is 21/8 x 1/8 inch. GL-25-HD by brown aircraft.com on the package. I took apart my gascolater and confirmed it is the right size. Also works for the fuel gauges. The originals were cork.

Thanks guys, appreciate it, I’ll put it on my Spruce wish list. Current one is still serviceable but hard and beginning to crack, so I expect next time it’s removed it won’t be.
