Eaton Crouse-Hinds ECLK233 coupling - 33in flexible length, 3/4in trade size
Part Number: ECLK233
Quick Summary
The Eaton Crouse-Hinds ECLK233 coupling is a flexible, explosion-proof conduit connector for hazardous locations. It addresses routing challenges in long runs by delivering a single 33-inch flexible section that simplifies installation and reduces the need for multiple fittings. This coupling carries UL certifications for EC explosionproof components and NEC/CEC compliance, with Class I, Division 1 (and related classifications) ratings to match harsh environments. By standardizing on this forged brass connector, procurement teams gain both safety assurance and inventory efficiency, while project engineers benefit from predictable performance in chemical, oil & gas, and marine settings.

Eaton Specification Sheet - ECLK233
Feature: 33" flexible length → Business Impact: enables easier routing and fewer rigid joints, reducing leak paths and maintenance needs → Application: long conduit runs in hazardous areas. Feature: Male on one end, female on the other → Business Impact: simplifies field assembly and stock management with common end fittings → Application: quick, reliable field assembly in tight spaces. Feature: Forged brass construction → Business Impact: improved durability and corrosion resistance in aggressive environments → Application: offshore platforms, refineries, and chemical plants. Feature: 3/4" trade size → Business Impact: compatibility with standard conduit systems minimizes custom adapters and delays → Application: integration with existing conduit networks. Feature: Hazardous/Classified Locations area classification and NEC/CEC compliance → Business Impact: regulatory peace of mind and faster permit approval → Application: projects requiring strict safety certifications and UL listings. Feature: 37.13 in product length/depth and 5.56 lb weight → Business Impact: predictable handling and installation planning in constrained spaces → Application: fixed-installation conduit runs in confined layouts. Objection handling: concerns about long-lead exotic parts are mitigated by standardization across EC explosionproof couplings and readily available UL-certified references. Industry context: designed to meet evolving hazardous-location codes, reducing retrofit needs and keeping sites compliant.

FAQs
The ECLK233 is an EC explosionproof coupling with a 33-inch flexible section and 3/4-inch trade size, designed for hazardous locations. It combines male and female ends in a forged brass body, enabling safe conduit connections in Class I, Division 1 environments across oil, gas, chemical, and marine applications.
Key specs include a 33-inch flexible length, 3/4-inch trade size, forged brass material, and a 37.13-inch overall product length with a 1.88-inch width and height. It features male and female connections on opposite ends and carries NEC/CEC compliance with hazardous location ratings.
The ECLK233 is UL-certified for EC Explosionproof fittings and complies with NEC/CEC standards. It is rated for Hazardous/Classified Locations (Class I, Division 1, and related divisions), ensuring regulatory compliance for hazardous-area installations.
Yes. The ECLK233 uses standard 3/4-inch trade sizing and male/female end configurations, enabling seamless integration with compatible EC explosionproof couplings, conduits, and associated fittings in existing hazardous-area systems.
Plan for the 33-inch flexible section to reduce fittings along long runs, confirm NEC/CEC and UL certification requirements, and inventory Forged brass components for corrosion resistance. Its standardized size and ratings support faster commissioning, lower maintenance costs, and lower total cost of ownership in harsh environments.
