Eaton Specification Sheet - ECLK28
Feature → Business Impact → Application: Forged brass construction delivers mechanical strength and corrosion resistance, improving durability in aggressive environments and reducing replacement frequency in chemical and petrochemical facilities. This translates to lower lifecycle costs and less maintenance interruptions during uptime-critical operations in hazardous locations. Application: Use in hazardous area conduit assemblies where a durable, reliable connection is required for EC explosionproof couplings. Feature → Business Impact → Application: 8" flexible length simplifies routing in tight spaces, enhancing installation efficiency and reducing field bending errors. This results in faster commissioning and improved conduit management in plant rooms or offshore platforms. Application: Ideal for service entrances and machine enclosures where limited maneuvering room demands a flexible, quick-connect solution. Feature → Business Impact → Application: 3/4" trade size provides standard compatibility with common conduit fittings, reducing inventory complexity and enabling plug-and-play replacements. Application: Suitable for retrofit projects or new builds needing consistent sizing with existing EC-series components. Feature → Business Impact → Application: Male and female ends ensure universal mating across Eaton Crouse-Hinds EC series, improving compatibility and minimizing mis-matches. Application: Useful in multi-point junctions and modular assemblies where interchangeable endpoints are beneficial. Feature → Business Impact → Application: NEC/CEC compliant with Class I, Division 1 ratings, ensuring regulatory alignment and safer operation. Application: Critical for facilities handling potentially explosive atmospheres, enabling compliant electrical installations. Feature → Business Impact → Application: Forged brass offers low maintenance and resistance to galvanic corrosion, extending service life in marine or humid environments. Application: Offshore, shipyards, or coastal plants where moisture exposure is common and downtime penalties are high.

FAQs
The ECLK28 is designed for Class I, Division 1 environments and other hazardous/classified locations. It joins conduit runs with an 8" flexible length and 3/4" trade size, enabling reliable, code-compliant terminations in refineries, chemical plants, and offshore facilities where safety and uptime are critical.
This coupling aligns with NEC/CEC requirements and is rated for hazardous locations. It features forged brass construction, 8" flexible length, and seamless male-female connections that support proper sealing and electrical integrity, reducing non-compliant rework and verification steps during audits.
Yes. The ECLK28 uses standard 3/4" trade size and features mating ends designed for Eaton Crouse-Hinds EC series. This compatibility streamlines retrofits and new installations alike, minimizing inventory fragmentation and facilitating quicker spares replacement.
Ensure proper torque on connections, verify seal integrity at both ends, and confirm compatibility with the conduit size. The 8" flexible length helps route cables around tight spaces, while the forged brass body resists corrosion, maintaining long-term reliability in marine or chemical environments.
Project teams can expect reduced field rework, faster commissioning, and tighter regulatory compliance. The device’s durability lowers maintenance frequency, while standardized sizing simplifies procurement and inventory management, delivering lower total cost of ownership over the lifespan of hazardous-area electrical systems.
