General

What this product is

Brass stop plugs (hex plugs, blanking plugs) close unused ports on manifolds, valves and pneumatic blocks. They look simple and fail incoming inspection when hex across-flats or thread class drifts. We machine BSP, NPT and metric plugs, slotted or hex head, and hold gauges on every lot. Nickel plating is available for appearance and corrosion.

Simple parts that fail incoming inspection if hex or thread drifts. We hold gauges on every lot.
