Construction

This cobalt blue ground glass bushing is made from colored glass with precision-ground standard taper joints. It is built as a reducing adapter with a 19/22 female joint on the outside and a 14/20 male joint on the inside, giving you a clean, stable way to connect two different joint sizes in one piece.

Why and when it is used in lampworking

Use this bushing when you need to step down from a 19/22 connection to a 14/20 connection in a scientific-style assembly. In lampworking and scientific glass setups, bushings like this are used to make mismatched joints compatible so you can connect smaller jointed components to a larger receiving joint without rebuilding the rest of the apparatus.

Dimensions

• Overall length: 6 inches
• Joint sizes: 19/22 female outside to 14/20 male inside
