Hazardous-Location Flex Coupling

This Appleton Century Crofts EXLK-14 flexible coupling connects 1/2-inch conduit in hazardous areas rated Class I Division 1 and 2, Class II Division 1 and 2, and Class III. The bronze body with a brass core provides a multi-angle connection that absorbs vibration and movement between rigid metal or intermediate metal conduit runs.

Replaces Rigid Conduit Joints

Use this coupling when a solid threaded joint cannot tolerate vibration, thermal expansion, or equipment movement in classified locations. The 4-inch flexible length and female-to-male NPT ends let you bridge misaligned fittings without adding separate elbows or unions, reducing potential leak paths in the sealing system.

Suits Classified-Area Installations

Electricians running IMC or RMC in refineries, grain elevators, or chemical plants will appreciate the natural-finish bronze construction and hazardous-location ratings. Builders needing a straight, non-flexible coupling or a different trade size should select a standard rigid fitting instead.

Questions about this item

What conduit trade size does the 1/2 in FNPT x 1/2 in MNPT hazardous fitting connect to?

It connects to 1/2 in trade size IMC or RMC conduit using the female and male NPT threads on each end.

How do you orient the multi-angle coupling during installation, and what step prevents leaks?

Position the coupling at the required angle, then tighten both NPT joints with pipe sealant on the threads to seal the hazardous-location fitting.

When should the bronze body and brass core be inspected or replaced?

Inspect after any vibration event or movement cycle; replace if the natural finish shows corrosion, thread damage, or the flexible section has fatigued.
