The brass hex nipple 1/4 inch joins two 1/4 inch female-threaded parts close together. This size suits gauge, instrument and small gas connections.
A hexagon in the middle takes a spanner. Therefore, it tightens firmly even in tight spaces, and the brass body does not rust.
What is a brass hex nipple 1/4 inch?
A brass hex nipple is a short connector with male BSP threads at both ends and a hexagon in the middle. It joins two female-threaded parts with almost no gap.
The hex lets you tighten it with a spanner. As a result, hex nipples suit tight valve, meter and regulator assemblies.
