So the O-ring for the sealing the Bottle to the extension....BS-119
To seal the Banjo.. It uses 2 BS-111..
1 between the Banjo and Bottle...1 between Banjo and Bottle Adapter..

Good Luck,
Stuart

Thanks Stuart,but it's the one in the foster fitting. It's a really small one,it stops air coming out when filled I've forgot how to put pictures on otherwise I would. Thanks md.
