Airbrush Air Hose Connector 1/8 BSP Male – 1/4 BSP Female x 2

Airbrush Air Hose Connector – BSP stands for British Standard Pipe thread.
This is the pitch, width and depth of the thread on the pipe.
You not only need to get the right diameter but also the correct thread type to couple to it.

A 1/8 fitting is commonly described as a 1/8″ fitting which is not exactly correct as the diameter is approximately 9.35mm (approx. 0.37 of an inch).
1/8 is the most common airbrush air inlet and air hose size.

This connector will fit directly to a 1/4 BSP Male outlet on your compressor or air regulator and reduce it down to a 1/8 BSP Male outlet.

A 1/4 BSP fitting is commonly described as a 1/4″ fitting which is not exactly correct as the diameter is approximately 11.75mm (approx. 0.46 of an inch).
This connector can be used to join a 1/4 BSP Male air outlet to a 1/8 BSP Female air hose inlet.
