Amerex 04892 Hydrostatic Test Adapter Assembly, CO2 Wheeled Unit / Nitrogen Cylinder

Wheeled CO2 units come due for hydro test as well, and this is the fitting that makes the connection. Amerex specifies this 3/4 in.-14 NPT hydro-test adapter for 50 lb. and 100 lb. carbon dioxide wheeled extinguishers. Buying it as a genuine OEM part means correct thread form on the first try.
