14/20 Male GG Joint (Economy)

14/20 Male GG Joint (Economy)

SKU: 2MC-ECONOMY

Construction

This is a double ended ground glass joint component made as a single piece with two ground joint grinds. It is manufactured to the 14/20 joint standard so it mates with other 14/20 ground glass components for a consistent, repeatable fit.

Use in lampworking

A double ended 14/20 male ground joint is used when you want to build modular scientific glass assemblies that can be taken apart for cleaning, reconfigured, or repaired without permanently sealing every connection. In lampworking, it is commonly used when fabricating adapters, connectors, and removable sections where standardized ground joints are required for compatibility with existing labware and jointed components.

When ordering ground glass joints, the 14/20 designation matters because it defines the joint interface you are building around, ensuring the finished piece will match other 14/20 fittings.
