Joints, Spherical, Male

Product Code : JA-SDAJ-1670

Joints, Spherical, Male (product code JA-SDAJ-1670) are the ball halves of ball-and-socket glass connections. Each male spherical joint has a ground glass ball on a 100 mm shank, ready for a glassblower to fuse into apparatus, and it seats in a female spherical joint of the same S size. The ball can swivel slightly in its socket, which takes up misalignment in long glass lines. Sizes S13 to S51 are listed, plus an S13 capillary bore version.

Specifications

These male spherical joints are listed with a 100 mm shank in seven options: S13 capillary bore, S13, S19, S29, S35, S41 and S51. The S number gives the joint size and must match the female joint it is paired with.
