Stainless Steel Vacuum Insulated Bayonet Connection for Cryogenic Pipe Helium Transfer Large 2", 3", or 5", etc.....
I have a lot of different sizes of these and variations of them. I will attach pics of the different ones....a lot of them look the same, but are slightly different in size / dimensions. I have a decent amount of these pieces, so please email me if interested in just one, or a large quantity. Thanks.
