Eaton Crouse-Hinds ECLK618 S758 Coupling - Class I Div 1
Part Number: ECLK618 S758
Quick Summary
The Eaton Crouse-Hinds ECLK618 S758 coupling is an explosion-proof connector for hazardous-location installations. Engineers often struggle with flex, moisture ingress, and corrosion on long conduit runs; this unit mitigates those risks. It aligns with NEC/CEC requirements and hazardous-location ratings, including Class I, Division 1, Class II, Division 1, and Class III. Designed for 2-inch trade size with a male-female connection and a flexible 18-inch section, it adapts to tight cabinets and equipment junctions. Along with a 24.5-inch overall length and a robust forged brass body protected by a flexible PVC coating, it reduces field time, simplifies compliance, and lowers maintenance costs.

FAQs
The ECLK618 S758 is designed for Hazardous/Classified Locations with a 2 in trade size. For installation, power is de-energized, and connections are made using the male and female ends per the EC Explosionproof catalog guidance. The unit’s 24.5 in length and 18 in flexible section enable routing around equipment in tight spaces, aligning with NEC/CEC requirements for Class I Division 1 environments. Compatibility with standard EC explosion-proof fittings ensures rapid field assembly and consistent performance under demanding conditions.
Key specs include a 2 in trade size, 24.5 in overall length, 18 in flexible section, and a forged brass body with a flexible PVC coating. It is rated for hazardous locations under NEC/CEC with Class I, Division 1 (and Class II/III in applicable configurations). The product weighs 22.85 lb and uses a male-female connection configuration, facilitating reliable, durable connections in challenging environments.
Industries such as oil and gas, chemical processing, petrochem refining, shipbuilding, and offshore platforms benefit most. The combination of explosion-proof construction, corrosion resistance, and flexible routing supports installations in refineries, marine facilities, and other hazardous-location sites where space constraints and harsh conditions demand robust, compliant couplings.
This coupling adheres to NEC/CEC standards for hazardous locations and carries Class I, Division 1 (with Class II and III ratings as applicable). Area classification is Hazardous/Classified Locations, and Canadian certification references are available via UL listings. Documentation includes Eaton’s specification sheets and UL/Canadian certification references to simplify audits and cross-border installations.
The forged brass with PVC coating offers superior corrosion resistance, reducing maintenance intervals and replacement costs in harsh environments. Its 18 inch flexible section and dual-end design shorten installation time, lowering labor and downtime. In long-term operations, the durable construction translates to lower total cost of ownership in hazardous-area facilities and marine environments.
