Hazardous-Location Conduit Plug

The Killark CUP-6 is a 2-inch aluminium blank plug designed to seal threaded conduit openings in hazardous environments. It carries Class I Division 1 and 2 ratings for Groups A through D, plus Class II and Class III ratings for Groups E through G. The male NPT threads allow direct installation into a hub or taped hole without additional adapters.

Installers Sealing Classified Areas

This plug suits electricians and maintenance teams closing unused entries in explosion-proof enclosures or conduit systems rated for flammable gases, vapours or combustible dusts. It is not intended for non-threaded openings, for conduit sizes other than 2-inch trade size, or for applications that require a through-connection rather than a permanent seal.

Male NPT Threads for Direct Hub Mounting

The fitting features 2-inch male NPT threads on both ends, enabling it to thread straight into a compatible hub or taped hole. Overall length measures 1 inch, while overall height and width are each 3 inches, and the unit weighs 0.4 lb.

Questions about this item

Should I pick the 2 in trade size plug for my 2 in conduit?

Yes, the 2 in trade size matches a 2 in conduit and the male NPT threads seal the hub or taped hole.

What does the 1 in overall length mean when the plug is installed?

The plug extends roughly 1 in into the fitting, leaving the 3 in square body flush with the conduit hub.

How does the male NPT thread affect the seal in hazardous locations?

The male NPT threads engage the hub or taped hole to meet Class I Division 1 and 2, Groups A–D and Class II Division 1 and 2, Groups E–G ratings.
