Eaton Specification Sheet - ECLK310
Forged brass construction delivers robust durability in corrosive or damp hazardous environments, reducing maintenance and total cost of ownership for critical installations in chemical plants and offshore facilities. The material’s strength supports long service life in harsh conditions, translating to fewer field repairs and safer operations. Dual-ended, male-one-end and female-one-end connections paired with a standard 1 inch trade size simplify procurement and installation, enabling quicker assembly and fewer mismatches in conduit systems found in industrial plants and marine environments. With a length specification of fifteen inches and a flexible segment noted at ten inches, installers gain routing versatility in tight enclosures and congested cable trays, improving overall project timelines. Compliance with NEC/CEC standards and NEC hazardous ratings (Class I, II, III) plus UL certifications provide regulatory assurance and reduce audit risk for hazardous-area projects. The compact dimensions (2.13 in width and height) and a weight of about 4.05 lb offer a manageable balance of sturdiness and handling ease, which lowers fatigue during field service. These attributes collectively improve installation reliability, cut downtime, and support cost-effective maintenance programs for hazardous area conduit fittings and explosionproof couplings.

FAQs
The ECLK310 uses a 1 inch trade size with male one end and female opposite ends, designed to fit standard conduit systems. Its forged brass construction supports reliable connections in hazardous environments, simplifying field assembly and reducing compatibility issues in complex installations.
The ECLK310 carries NEC/CEC standards alignment with Hazardous Location ratings including Class I, Division 1 (and related Class II/III scopes) and area classification guidance. UL certifications for both US and Canada further validate its explosionproof performance and regulatory compliance in hazardous areas.
Typical applications include chemical processing plants, offshore platforms, and marine electrical installations where durable, explosionproof conduit connections are required. The product’s brass construction and flexible routing capabilities support reliable performance in confined spaces and challenging environments common to these industries.
The ECLK310 is NEC/CEC compliant with hazardous location ratings and UL listed for explosionproof operation in both the United States and Canada. Certification documentation is available through UL references and Eaton’s specification materials for confirmation of compliance.
Ensure proper alignment of male and female ends, follow safe routing practices for the 15 inch length with a ten inch flexible section, and verify the 1 inch trade size fits the conduit run. Using UL/NEC compliant components reduces rework, lowers maintenance costs, and minimizes downtime in hazardous-area installations.
