Chinese Joints

Imported ground glass joints and fittings in borosilicate — standard taper joints, ball-and-socket connections, and related scientific glass components at value pricing. Used in scientific apparatus, functional glass, and anywhere a standardized ground-glass connection is needed.

Joints are sized by standard taper designation (such as 14/20 or 24/40) or ball size; mating parts must share the same designation to seal properly.
