Eaton Crouse-Hinds ECLK336 Coupling - Hazardous Location
Part Number: ECLK336
Quick Summary
Eaton Crouse-Hinds ECLK336 coupling provides a flexible, reliable connection for hazardous-area conduit in industrial installations. Operators often struggle with rigid fittings that fail under temperature swings or exposure to corrosive atmospheres, leading to leaks and downtime. This coupling carries NEC/CEC compliance and hazardous-location ratings — Class I, Division 1; Class II, Division 1; Class III — to support safe, code-compliant installations. Designed for 36-inch flexible length with 1-inch trade size, forged brass construction, and opposite-end female/male connections, it enables fast field assembly and durable performance. For procurement teams, this module supports predictable performance, smoother compliance audits, and lower total ownership costs over the asset lifecycle.
