  • Product typeCable Management & Conduit
  • Hazardous-location rated for Class I, II, III environments

Hazardous Location Coupling

The Killark ECFUF-224 is a flexible conduit coupling rated for hazardous locations. It provides a flexible connection where movement or vibration makes rigid conduit impractical. The unit is constructed from bronze and carries Class I Division 1 and 2, Groups A through D ratings. It suits industrial electrical installations requiring code-compliant flexibility.

24 in Flex Length Headroom

The coupling offers a 24 in flexible length with an overall length of 30 1/4 in. This accommodates difficult bends and equipment vibration in conduit systems. It connects 3/4 in trade size conduit via female to male NPT threads. The assembly is not intended for straight-run installations where rigid conduit is specified.

3/4 in NPT Thread Interface

The decisive specification is the 3/4 in FNPT by MNPT threaded connection. This determines compatibility with existing conduit entries and fittings. Buyers needing a different thread size or a non-threaded coupling must select another part. Verify the thread gender and trade size match your system before ordering.

Questions about this item

Will the 3/4 in FNPT and MNPT ends thread onto my existing 3/4 in conduit fittings?

Yes, both ends are 3/4 in tapered pipe threads — female on one side, male on the other — so they match standard 3/4 in rigid or IMC conduit couplings.

How can I verify the coupling is rated for my Class I Division 1 area after installation?

The bronze body carries the hazardous-location marking for Class I Division 1 and 2 Groups A B C D, Class II Division 1 and 2 Groups E F G, and Class III — visible on the fitting once mounted.

Does the 24 in flexible section come pre-assembled or do I need to buy a separate whip?

The unit ships as a single 30 1/4 in overall assembly with the 24 in flexible bronze whip permanently attached to the threaded ends — no extra parts required.
