Posted for "Gary Melton" <n320g@hotmail.com>:

Can anyone help me find the part number for this o-ring.  I bought the
Gasccolator from Aircraft Spruce and so far they have not been able to come
up with a replacement part number for me.

The measurements are  OD  1 11/16      ID  1  9/16

Any help is appreciated.

[Normally I would just look up the part number in McMaster-Carr's online catalog and shoot it off to you.  I checked their o-ring selections in silicone, neoprene, and viton, and in every instance if I selected a 1/16" width all of the ID's and OD's after 1-3/8" only progress in 1/8" increments.  If I select your specific ID or OD it shows that the thinnest they're available in is 3/32", so a 1-9/16 ID ring will have an OD of 1-3/4. I have to believe that they have what you're looking for and can probably sell you 25 of them (smallest package available) in any of those materials for about what an aircraft parts house will try to charge you for one "aircraft" part.  Give McMaster a call and ask them about it, I'll bet it's a stock item.  Go to www.mcmaster.com.
