View Full Version : O-ring question
06-03-2006, 07:52 PM
This may be a dumb-ass question, but are all O-rings the same size? What I am getting at, can I use the same O-ring for a tank that I can use for a barrel?
The o-rings are the same size but not all the same material and yes they are the same size as the tank o-ring.
This is from Otter's website so thank him before you thank anyone else.

they're all pretty much the same ... go to www.mcmaster.com and put in o-ring for the search go for number 15 on the dropdown .. then click on buna-N, standard, and then there you go !! :) cheap and great
100 for 3.06 excluding shipping, and since you have the newer spyder (slim striker) it'll fit all
