Appleton PLG-400 4-Inch Threaded Conduit Plug
This galvanised malleable-iron plug seals a 4-inch threaded IMC or rigid metal conduit run in hazardous locations. It carries Class I Division 1 and 2, Groups A through D, Class II Division 1 and 2, Groups E through G, and Class III ratings. The straight male-to-male NPT fitting measures 5/8 inch overall length. Suitable for new conduit installations requiring a listed hazardous-area closure.
Installers closing unused conduit entries
Electricians finishing IMC or rigid conduit systems in refineries, grain elevators or chemical plants will find the fitting matches the required trade size and hazardous ratings. Projects needing a female-threaded cap, a non-metallic plug or a fitting for EMT conduit cannot use this part. Buyers requiring a larger or smaller trade size must select a different plug.
4-inch trade size with Class I Division 1 rating
The 4-inch trade size and hazardous-location certification are the decisive specifications; they determine whether the plug fits the conduit and meets the area classification. No other dimension or rating in the data overrides this requirement. Verify the conduit type and trade size before ordering.

Questions about this item
Should I choose the 4 in trade size plug for my IMC conduit?
Yes — the PLG-400 is a 4 in trade size male plug designed for IMC and threaded rigid conduit of the same size.
What does the 5/8 in overall length mean when the plug is installed?
The plug extends 5/8 in beyond the conduit end, sealing the opening in hazardous-location enclosures.
How do the Class I Division 1 and 2 ratings limit where this galvanized iron plug can be used?
The ratings certify the plug for explosive gas atmospheres Groups A–D and combustible dust Groups E–G, so it can seal conduit in those classified areas.
