Precision 19/22 Male Quartz Joint

This item is sold by each end.

Precision Ground Joints! A step up from China imported joints, but still affordable with quality you can trust. 19/22 male socket joint, 5.5" in length. When ordering ground glass joints you must consider measurements (X/Y=) Where X is the Top Outer Diameter, and Y is the Length of the Grind. (So 19/22 would be a Top Outer Diameter of 19mm and a grind length of 22mm.)
