Zoro Select 1MPL8 Hex Head Plug

The Zoro Select 1MPL8 is a 1-inch male NPT hex head plug designed for piping systems. It features a galvanised forged steel construction rated to Class 3000 for durable service. This bathware fitting helps close off pipe ends in residential or commercial installations. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Suitable for standard NPT pipe closure

This plug suits installers needing a Class 3000 forged steel fitting with male NPT threads. It is not intended for systems requiring a pre-applied thread sealant or an included gasket. Buyers needing different pressure classes, materials, or thread types should select an alternative fitting. The transparent colour identifies the component in stock.

Class 3000 pressure rating

The single specification that determines suitability is the Class 3000 pressure rating on forged steel. This rating defines the fitting's pressure-temperature envelope for the intended piping system. Verify that your design pressure and temperature fall within this class before installation. No other pressure class applies to this specific part.
