Appleton Century Crofts PLG-125 IMC Plug Conduit

SKU CH-Z5AT-BFNEP

Threaded malleable iron plug seals 1-1/4 inch IMC conduit in hazardous locations

  • Product typeCable Management & Conduit
  • Threaded 1-1/4 in male plug seals IMC conduit
  • Malleable iron body with galvanised finish resists corrosion
  • Hazardous-location rated for Class I, II, Division 1 and 2
  • Straight orientation simplifies installation in tight runs
  • Blank plug design closes unused conduit openings securely

Application & purpose

The Appleton Century Crofts PLG-125 IMC plug seals a 1-1/4 inch threaded conduit end in hazardous locations. It suits electrical contractors and maintenance teams who must close unused entries on IMC or threaded rigid metal conduit systems rated for Class I, II and III divisions.

Thermals, noise & power

As a passive malleable iron fitting with a galvanised finish, the plug generates no heat, emits no noise and draws no power during normal operation. Its metal construction simply maintains the conduit’s mechanical integrity and environmental seal without active components.

Bundled items & software

The product ships as a single blank plug with no additional accessories, gaskets or software. Installers must supply their own thread sealant or compound if the specific hazardous-location rating requires it for the intended division and group classification.

Questions about this item

How do I install the PLG-125 IMC plug into a 1-1/4 in threaded conduit, and what step is often missed?

Thread the male NPT end into the conduit until tight; the step often missed is applying a listed thread sealant to maintain the hazardous-location rating.

What maintenance or replacement will the PLG-125 IMC plug need over time?

Inspect the galvanized finish and threads periodically for corrosion or damage; replace the plug if the coating is compromised or threads are stripped to preserve the hazardous-location seal.

What limit appears first on the PLG-125 IMC plug during sustained use in a hazardous location?

The galvanized coating is the first limit; once it degrades, the iron substrate can corrode and the Class I, Division 1 and 2 rating is no longer assured.
