Brass Adapter, 1/2-14 Male NPT Square Head Plug

Being made of brass, this plug offers good corrosion resistance, which is helpful for longer life in tougher environments.

Brass construction and a minimum working temperature of -65 degrees make it a solid fit for refrigeration applications. It also handles grease, instrumentation, and hydraulic systems, so it covers a fairly wide range of uses. The 1/2-14 NPT thread with a PTF SAE short end gives you a secure connection across those environments without needing a dedicated refrigeration-specific fitting.
