29/26 Male GG Joint

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 29/26 would be a Top Outer Diameter of 29mm and a grind length of 26mm) These are made on 26mm x 4.0mm tubing and have approximately 6" of glass past the grind. This item is double ended. Each end is sold separately.
