Precision Ground Joints! A step up from China imported joints, but still affordable with quality you can trust. Double Ended 14/23 cone joint with drip tip, Male 6.25″ 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.
