Steel Adapter, 0.63 Inch O-Ring Face Seal Shoulder Internal Braze

Tube O.D. runs 0.63 inch on this one, which lines up with standard 5/8 inch tubing. The shoulder dimension listed as F is also 0.63, so the sealing surface and tube size are consistent with each other. Dimensions A and B come in at 0.42 and 0.38 respectively, which cover the internal geometry of the braze connection. If you're working with 5/8 O.D. tubing and need an O-Ring Face Seal shoulder for a brazed assembly, the sizing here should match up without any modification.
