Plug Metric Fittings

Metric Plugs with M3, M5 and M6 threads are machined from brass and electroless nickel plated for corrosion resistance. The M5 and M6 fittings feature our popular o-ring design which provides a superior seal and leak resistant fit, even when installed in a less than perfect sealing surface. A screwdriver slot eases fitting installation.
