Eaton Specification Sheet - ECLK812
Feature: Stainless steel construction provides excellent corrosion resistance in saline and chemical environments. Business Impact: Extends service life, lowers maintenance cost, and reduces replacement frequency for hazardous-area fittings. Application: Offshore platforms, chemical plants, and refinery pipelines benefit from long-lasting performance and reduced lifecycle costs. Feature: 12 inch flexible length enables easier alignment of non-linear conduit runs. Business Impact: Faster installation, fewer field modifications, and reduced labor costs. Application: Complex plant layouts and retrofit projects where rigid fittings would complicate routing. Feature: 3 inch trade size supports compatibility with common conduit systems while maintaining rugged protection. Business Impact: Streamlined sourcing and fewer adapter components, accelerating project schedules. Application: Industrial facilities with standard 3 inch conduit workscopes. Feature: Male on one end and female on the opposite end simplifies assembly and reduces installation steps. Business Impact: Time savings during assembly and lower error risk in field conditions. Application: Frequent reconfigurations or modular installations in hazardous areas. Feature: 18.25 inch overall length and 14.8 lb weight balance robust mechanical strength with manageable handling. Business Impact: Predictable performance under vibration and physical stress, lowering failure risk. Application: Marine and plant applications subject to movement and impact. Feature: UL hazardous-location certifications and NEC/CEC compliance provide regulatory assurance. Business Impact: Compliance-driven project approvals and safer, auditable installations. Application: Any facility operating in Class I, II, III hazardous locations requiring certified fittings.

FAQs
Plan around the 12 in flexible length and 3 in trade size to align with your conduit runs. Verify area classification, shut down power, connect male and female ends securely, and follow NEC/CEC guidelines. Use stainless hardware and torque as specified by the Eaton installation sheet to ensure a compliant, leak-free fit in Class I, II, III locations.
The ECLK812 carries UL hazardous-location certifications for the U.S. and Canada and NEC/CEC compliance. It supports Class I, Division 1, Class II, Division 1, and Class III environments, providing documented protection for hazardous locations and enabling regulatory approvals for industrial installations.
Yes. The stainless-steel construction and EC explosion-proof design are crafted for hazardous-area environments common in offshore platforms and chemical processing plants. Its rugged build and compliance with NEC/CEC standards make it a reliable choice for tough service conditions and regulatory expectations.
The stainless-steel ECLK812 resists corrosion in marine and chemical environments, reducing replacement frequency and maintenance downtime. While initial cost is higher than generic fittings, the long service life and lower maintenance requirements translate to a favorable total cost of ownership over time.
The ECLK812 has a 12 in flexible length, 18.25 in overall length, 4.56 in width and height, and a 3 in trade size with male and female ends. It uses stainless steel construction for durability in hazardous locations and is compatible with standard conduit assemblies meeting NEC/CEC requirements.
