Appleton PLG-100RA IMC Plug for Hazardous Locations

This threaded aluminium plug seals a one-inch IMC conduit end in Class I, Division 1 and 2 areas rated for Groups A through D, Class II Groups E through G and Class III environments. It suits electrical contractors and maintenance teams who need a listed hazardous-location fitting for rigid metal conduit systems.

Straight Threaded Installation with Male NPT Ends

The plug installs by threading its male NPT ends directly into the conduit fitting, requiring only standard conduit tools and no specialised equipment. The plain aluminium finish provides corrosion resistance, but installers must verify thread engagement and torque to maintain the hazardous-location rating without damaging the relatively soft aluminium body.

Limited to One-Inch IMC and Threaded RMC Conduit

This fitting accepts only trade-size one-inch IMC or threaded rigid metal conduit, so it cannot be used with EMT, PVC or larger conduit sizes. The 5/8-inch overall length leaves minimal protrusion, yet the hazardous-location rating applies only when the plug is fully tightened into a compatible threaded hub; open or mismatched threads void the classification.

Questions about this item

How can I confirm the PLG-100RA plug is correctly installed in the conduit?

The plug threads into the 1 in IMC or threaded RMC conduit; when the male NPT end seats fully, the 5/8 in overall length sits flush with the conduit face, indicating a secure hazardous-location seal.

What comes with the PLG-100RA and what must I supply?

The package contains the aluminum galvanized plug only; you must provide the 1 in IMC or threaded RMC conduit and any thread sealant required for the Class I, Division 1 and 2 installation.

Which version of this plug should I select for a 1 in hazardous-location run?

Choose the PLG-100RA model; it is the 1 in trade-size plug rated for Class I Groups A–D, Class II Groups E–G and Class III hazardous locations.
