Joint, spherical w/ o-ring seal 50MM, ace 7646-16
Ace Spherical O-ring Sealed Joint
Unused, in the original box, a N.O.S. (new old stock) Ace #50 joint. No chips or cracks. Each piece has one to a few short lines from manufacture at some point on the tube. These appear to be very shallow and narrow air bubbles. They are short, typically less than 1 cm long. The lines run directionally from the rim to the socket joint (not cracks - the lines are extremely narrow and straight; and do not nearly penetrate the full glass thickness, as a crack would). These are common due to the wide cylindrical area of the pieces and the large size of joint.
Supplied with a #229 o-ring that is most likely composed of FETFE.
