Iron conduit plug for hazardous locations

The Appleton Century Crofts iron conduit plug is a hazardous-location fitting rated for Class I Division 1 and 2 Groups A through D, Class II Division 1 and 2 Groups E through G, and Class III environments. It seals a 3 in trade size threaded rigid metal or intermediate metal conduit run with a straight male-to-male NPT connection.

Verify conduit trade size and thread compatibility

Confirm that the existing conduit system uses 3 in trade size IMC or threaded RMC with male NPT ends before ordering. The fitting’s overall length is 5/8 in, so ensure the junction box or enclosure allows sufficient thread engagement for a secure, code-compliant seal.

Electroplated iron body resists corrosion in harsh

The silver electroplated HAWA iron construction withstands moisture, chemicals and mechanical abuse typical of industrial and classified areas. Straight orientation and male-to-male threads simplify installation in tight conduit bodies while maintaining the hazardous-location rating without additional sealing compounds.

Questions about this item

Does the PLG-300 conduit plug come with any gaskets or sealing washers, or must those be purchased separately?

The plug is a single iron casting with an electroplated finish; no gaskets or washers are included, so any required sealing components must be sourced separately.

The listing shows trade size 3 in and overall length 5/8 in — which dimension determines the correct fit for my conduit?

The 3 in trade size matches 3 in IMC or threaded RMC conduit; the 5/8 in overall length is the installed protrusion and does not affect conduit compatibility.

What does the Class I Division 1 Groups A–D rating mean when the plug is installed in a live hazardous-area enclosure?

It certifies the plug for use in atmospheres containing acetylene, hydrogen, ethylene or propane vapours when correctly threaded into 3 in IMC or RMC conduit in a Division 1 or 2 location.
