Flexible conduit coupling for hazardous locations

The Appleton Century Crofts EXLK-224 is a 24 in flexible coupling rated for Class I, Division 1 and 2, Groups A, B, C, D and Class II, Division 1 and 2, Groups E, F, G. It connects 3/4 in FNPT to 3/4 in MNPT ends on IMC or RMC conduit where vibration or movement is a problem. Bronze construction with a brass core provides the required hazardous-location rating.

Natural finish bronze resists corrosion without

The Natural Finish bronze body with brass core handles the environmental demands of hazardous areas without extra coatings. Multi-angle connection orientation allows the coupling to absorb movement and vibration in normal use. Overall length is 29 1/2 in while the flexible section measures 24 in, giving a compact profile for tight routing.

No bundled accessories or software included

The product ships as a single coupling with no additional fittings, sealants or configuration tools. Installers must supply compatible 3/4 in IMC or RMC conduit and any required hazardous-location sealing compounds separately. The 30.500 specification length confirms the manufactured dimension for layout planning.

Questions about this item

How do I install the EXLK-224 flex coupling and what step is commonly missed?

Thread the 3/4 in FNPT end onto rigid conduit and the 3/4 in MNPT end into the fitting, then tighten both joints to maintain the hazardous-location seal; the step often missed is confirming full thread engagement on the male side before final torque.

What maintenance or replacement will the EXLK-224 need over time?

Inspect the bronze housing and brass core periodically for corrosion or fatigue cracks, especially where vibration occurs; replace the coupling if the flexible section shows permanent deformation or the threads no longer seal to Class I Division 1 requirements.

What limit appears first on the EXLK-224 during sustained vibration?

The 24 in flexible length absorbs movement up to its multi-angle design limit; sustained vibration beyond that range stresses the bronze-to-brass interface and the 3/4 in NPT threads, making thread seal integrity the first failure point.
