Conduit plug for hazardous locations

The Appleton Century Crofts PLG-100R is a 1-inch steel conduit plug rated for Class I, Division 1 and 2, Groups A, B, C, D, Class II, Division 1 and 2, Groups E, F, G, and Class III hazardous areas. It threads directly into IMC or threaded rigid metal conduit with a straight male-to-male NPT connection. The electroplated finish resists corrosion in demanding industrial environments. This fitting seals unused conduit openings to maintain enclosure integrity.

Steel construction withstands continuous exposure

The steel body and electroplated finish are built for sustained service in corrosive atmospheres and locations where flammable gases, vapours, or combustible dusts are present under normal operating conditions. The hazardous-location ratings apply to continuous-duty installations, not only brief fault events. The 5/8-inch overall length keeps the profile compact inside tight enclosures while maintaining the required thread engagement. No moving parts or seals degrade over time.

1-inch trade size matches conduit exactly

The single specification that determines fit is the 1-inch trade size, which must match the conduit and the female-threaded opening precisely. This plug is not for buyers who need a different trade size or a non-threaded compression fitting. It is also not for installations that require a reducing plug or a fitting rated for a different hazardous-location group. Verify the conduit type and trade size before ordering.

Questions about this item

Does the steel plug generate any heat or noise when left installed in a live conduit run all day?

The PLG-100R is a solid steel blank plug with no moving parts or electrical components, so it produces no heat and makes no noise during continuous use.

What conduit and threading must already be in place for this 1 in plug to seal the opening?

It requires a 1 in trade-size IMC or threaded RMC conduit with a female NPT opening to accept the male-threaded end.

Will the electroplated finish on this plug hold up when threaded into older galvanised or black-iron conduit?

The electroplated steel body resists corrosion and threads cleanly into existing galvanised or black-iron 1 in NPT fittings without galling.
