Glass on Glass Size Adapter - 14 to 18mm

3 reviews
Use standard 14mm slides with 18mm downstems

Glass on glass adapter that fits 14.4mm male pieces into a 18.8mm joint.

Works with all standard 14.4mm glass slides if you want to us with a larger downstem.

It goes both ways. Use as a 14 to 18mm female adapter as well. Hook up larger domes or reverse bowls to smaller joints.
