Eaton ECLK827 Coupling - NEC/CEC Class I Div 1
Part Number: ECLK827
Quick Summary
The Eaton ECLK827 coupling is a rugged stainless steel conduit connector designed for hazardous locations, enabling flexible runs and reliable splicing in explosion-proof systems. Maintenance teams often struggle with bulky rigid assemblies and uncertain certifications when upgrading legacy equipment. This model carries NEC/CEC compliance and hazardous location ratings, including Class I Division 1, with related Class II and III classifications for safe operation in demanding environments. By offering a 27 inch flexible length and a 3 inch trade size, it streamlines installation, reduces field fittings, and helps meet safety documentation requirements while delivering better uptime and lower lifecycle costs for facilities working in chemical processing, oil and gas, or offshore environments.

Eaton Specification Sheet - ECLK827
Stainless steel construction provides corrosion resistance and long service life in aggressive environments, reducing maintenance cycles and total cost of ownership for hazardous area installations. The 27 inch flexible length enables rapid alignment of conduit runs, minimizes the need for additional fittings, and improves install efficiency across compact or congested spaces where strict tolerances apply. With a 3 inch trade size and a dual gender configuration (male one end, female on the other), integration with standard EC explosion-proof fittings becomes straightforward, supporting faster commissioning and simpler field modifications. Hazardous area ratings and NEC/CEC compliance give engineers confidence to deploy in Class I, Division 1 facilities, enhancing safety compliance while enabling standardized splicing across multiple projects. Overall dimensions (33.25 in length, 4.56 in height and width) and a 17.65 lb weight aid in planning, routing, and mounting, reducing unexpected installation challenges. Documentation and UL certification references further support procurement, quality control, and cross-site consistency in industrial environments requiring robust stainless steel conduit fittings. The ECLK827 aligns with industry best practices for explosion-protected connectors, delivering reliability that translates into reduced downtime and predictable maintenance planning.

FAQs
When installing the ECLK827 in hazardous locations, ensure mounting access allows full engagement of the male and female connections, verify the 3" trade size compatibility with existing EC explosion-proof fittings, and plan for the 27" flexible section to minimize field bending. Use appropriate safety procedures for Class I Division 1 environments and confirm NEC/CEC compliance for the specific location.
The 27-inch flexible length reduces the number of additional fittings required, enabling quicker routing around obstacles and easier alignment with pre-installed conduit runs. This translates to shorter installation times, fewer potential leak points, and a lower risk of improper connections in tight or complicated layouts common in chemical plants and offshore facilities.
Yes. The ECLK827 is designed for hazardous/classified locations and carries NEC/CEC compliance with NEC hazardous ratings for Class I, Division 1 (and related Class II/III). This makes it appropriate for chemical processing plants, oil and gas facilities, and other environments where explosion protection and regulatory compliance are required.
The ECLK827 carries NEC/CEC compliance for hazardous locations and is supported by UL certification reports for explosion-proof couplings. It is listed for Class I, Division 1 service, and the EC catalog page provides official documentation. These certifications help ensure regulatory alignment, safe operation, and streamlined procurement across projects requiring certified hazardous location fittings.
The stainless steel construction resists corrosion, reducing the need for frequent replacement in harsh environments and lowering maintenance costs. The 27 inch flexible length minimizes fittings and installation time, delivering faster commissioning and reduced labor costs. Overall, this results in improved uptime, predictable lifecycle planning, and a favorable return on investment for facilities relying on robust explosion-proof conduit fittings.
