Flexible Conduit Coupling for Hazardous Areas

This Appleton Century Crofts coupling connects 3/4 in IMC or RMC conduit in hazardous locations. The bronze construction resists corrosion while the 18 in flexible length absorbs vibration and movement. It is rated for Class I, II and III Division 1 and 2 environments. The fitting suits industrial electrical installations where rigid pipe cannot accommodate motion.

3/4 in Trade Size with Multi-Angle Orientation

The coupling accepts 3/4 in trade size conduit and provides an overall length of 23 1/2 in. Female to male NPT threads allow direct connection to enclosures or fittings. Multi-angle orientation lets installers route conduit around obstacles without stress on terminations. The bronze body maintains grounding continuity throughout the flex section.

Replaces Rigid Nipples in Vibration Zones

This coupling replaces rigid nipples or unions where equipment vibration or thermal expansion would fatigue threaded joints. The flexible design prevents conduit cracking and maintains hazardous-location integrity. The upgrade is worth it when movement exceeds what rigid fittings can tolerate, especially in Class I Division 1 areas with Groups A through D gases.

Questions about this item

Will the 3/4 in FNPT and MNPT ends thread onto the IMC and RMC conduit I already have installed?

Yes, the coupling is listed as compatible with 3/4 in trade size IMC and RMC conduit, and its ends are 3/4 in FNPT x 3/4 in MNPT for direct threading.

How can I verify the multi-angle orientation is functioning correctly once the 18 in flex section is installed?

After installation, the coupling should allow movement and vibration absorption at multiple angles without binding; smooth articulation through its range indicates it is working as intended.

Does the EXLK-218 come with any gaskets, locknuts or sealing compound, or must I purchase those separately?

The supplied data lists only the coupling itself with its 18 in flexible length and 23 1/2 in overall length; any gaskets, locknuts or sealant would need to be sourced separately.
