Eaton ECLK110 S758 Coupling - Hazardous/Classified Locations
Part Number: ECLK110 S758
Quick Summary
The Eaton Crouse-Hinds ECLK110 S758 coupling is a rugged, 10-inch flexible connector for hazardous-area installations. A common pain point is maintaining alignment and protection in harsh environments while meeting code requirements. This solution conforms to NEC/CEC, carries hazardous-location ratings, and is UL-listed for explosion-proof use, supporting Class I, Division 1, II, and III environments. By leveraging forged-brass construction and a flexible PVC coating, it enables longer runs with fewer joins, reducing installation time and lifecycle costs for industrial plants, refineries, and offshore facilities.

Eaton Specification Sheet - ECLK110 S758
Feature: 10-inch flexible length with a 1/2-inch trade size and opposite-ended male and female connections. Business Impact: speeds installation, minimizes fittings, and improves routing in constrained hazardous-area spaces. Application: long conduit runs in chemical plants and offshore facilities. The forged brass body delivers durability and corrosion resistance in demanding environments, reducing maintenance cycles and extending service life. Feature: Flexible PVC protective coating adds moisture and abrasion resistance, enabling reliable operation in marine and industrial settings. Application: protective coating is beneficial for equipment exposed to washdowns and salt spray. Feature: NEC/CEC compliance with Hazardous Location ratings (Class I, Division 1; Class II, Division 1; Class III) and UL explosion-proof certification. Business Impact: supports regulatory approvals and safer energy management in refineries, oil & gas terminals, and chemical processing. Application: engineering deployments requiring robust electrical fittings that meet global standards. Feature: Overall dimensions and weight (13.75 in length, 1.5 in width, 1.5 in height, 2.6 lb) provide a reliable, scalable solution for field installations. Business Impact: reduces inventory complexity and accelerates large-scale builds. Application: plant expansions and offshore installations with standardized EC explosion-proof couplings. Compatibility and installation advantage: male/female ends simplify field connections and minimize alignment issues, while the coating and material choices improve long-term reliability in harsh environments. Industry context: these characteristics align with best practices in hazardous-area conduit fittings and industrial automation projects requiring certified, rugged connectors.

FAQs
Yes. The ECLK110 S758 is designed as part of the Crouse-Hinds EC explosion-proof family, featuring opposite-ended male and female connections in a 1/2 inch trade size and a 10 inch flexible length. It pairs with EC fittings for hazardous locations and carries UL explosion-proof listings under NEC/CEC. Always verify compatibility with your existing conduit system and fittings.
The coupling carries NEC/CEC compliance along with hazardous-location ratings and UL explosion-proof certification. These assurances confirm enclosure integrity, ignition protection, and safe operation in Class I Division 1, Class II Division 1, and Class III environments, supporting regulatory approvals and safer maintenance in oil & gas, chemical processing, and marine settings.
The 10-inch flexible length reduces the number of joints and simplifies alignment in confined conduit runs. Combined with a forged-brass body and PVC coating, it improves install speed, reduces risk of misalignment, and lowers commissioning time on complex hazardous-area installations across plants and offshore facilities.
In marine environments the PVC coating protects against moisture and abrasion, while the forged brass body offers durability against corrosion and vibration. Regular visual inspections of the coating and joints are recommended, but overall lifecycle maintenance is typically reduced due to robust materials, translating to lower downtime and lifecycle costs.
Start by inspecting ends for cleanliness and coating integrity. Align the male and female ends, connect without forcing, and confirm the 1/2 inch trade size matches the conduit. Follow NEC/CEC guidelines, apply any required gaskets, and perform a final seal check. Verify UL labeling before energizing the circuit to ensure safety and compliance.
