Anyone know the O-Ring size on an Air Venturi Jubilee Valve, 7/8 inch? Brandy Spanking new 74cf Wingman tank, filled and O-Ring blew. I've contacted PA, but does any one know the size or a decent way to figure it out?
The o-ring size for a 7/8-14 valve is a 116. I'd buy 90 durometer buna o-rings rather than 70 durometer if I was ordering some. Make sure your valve is tight enough to not see any of the o-ring which means no visible gap between the valve and the tank. You should only tighten it hand tight.
Humdinger - thanks for getting back, but after measuring, it's closer to a 212. I have the good old Harbor Freight collection. The 116 is too small, the 212 is much closer. Thanks for getting back though, made me go look and figure it out!
