Application & Fit
The Killark PLUG6 is a 2-inch recessed conduit plug designed for hazardous-location electrical systems. It provides a male-to-male threaded seal for 2-inch trade-size conduit hubs or tapped holes. The fitting carries Class I Division 1 and 2, Class II Division 1 and 2, and Class III Division 1 and 2 ratings across multiple gas and dust groups. It is not intended for non-hazardous general-purpose conduit runs or for trade sizes other than 2 inches.

Questions about this item
How do I install the PLUG6 into a 2-inch threaded hub, and what step is often missed?
Thread the male NPT end into the hub until the recessed face sits flush. The step often missed is applying PTFE tape or pipe-thread sealant to the threads before tightening.
Will the electroplated finish need recoating or replacement in a hazardous-location installation?
The electroplated steel resists corrosion under normal service; inspect periodically for coating damage or rust, and replace the plug if the finish is compromised or threads are worn.
What is the first limit reached when the PLUG6 is used continuously in a Class I Division 1 area?
The plug carries no current, so heat is not a limit; the first limit is mechanical — thread galling or seal degradation from repeated removal and re-installation.
