Eaton Crouse-Hinds ECLK26 S758 6" PVC-Coated Class I Div 1
Part Number: ECLK26 S758
Quick Summary
The Eaton Crouse-Hinds ECLK26 S758 coupling provides a flexible, reliable conduit connection for hazardous-location installations. It helps protect critical electrical runs in demanding environments where space is limited and maintenance must be minimized. A common pain point is improper seals and rigid fittings that can leak or ignite in hazardous areas; this design mitigates that risk. The unit is NEC/CEC compliant and rated for Class I, Division 1; Class II, Division 1; and Class III locations, supporting broad project approvals. With a 6-inch flexible section, a 3/4-inch trade size, and a forged brass body with a flexible PVC coating, it combines installation efficiency with long-term durability for industrial plants and marine environments.

Eaton Specification Sheet - ECLK26 S758
Feature: 6-inch flexible length with male and female ends plus a 3/4-inch trade size. Benefit: Enables rapid, adaptable routing in tight spaces, reducing installation time and need for adapters in complex conduit runs. Application: Ideal for compact control panels and hazardous-area installations where space is at a premium and reliability matters. Feature: Forged brass construction with a flexible PVC protective coating. Benefit: Delivers superior mechanical strength and corrosion resistance while protecting the fitting from moisture and chemical exposure, lowering replacement costs. Application: Offshore rigs, chemical plants, and heavy-industrial facilities where harsh environments prevail. Feature: Hazardous-location ratings (NEC/CEC) including Class I Division 1, Class II Division 1, and Class III. Benefit: Ensures regulatory compliance and safer operation, supporting project approvals and insurance requirements. Application: Any installation in hazardous or classified locations requiring robust, code-compliant couplings. Feature: Compact overall geometry with roughly 10.13 in length and 1.88 in width/height, weight around 1 lb. Benefit: Easy handling and reduced headroom impact during installation, shipping, and service calls. Application: Marine, mining, and factory floors where weight and space constraints matter. Feature: Flexible PVC coating plus glandless or standard termination behavior (male one end, female on the other). Benefit: Simplifies field terminations and extends service life by protecting joints from abrasion and environmental ingress. Application: Routine maintenance workflows and retrofit projects in hazardous areas.

FAQs
Yes. The ECLK26 S758 uses a 3/4" trade size and features a 6" flexible segment that eases routing around tight bends and confined spaces. This flexibility reduces the need for additional fittings and adapters, speeds up installation, and minimizes potential leakage points in compact control panels or instrument enclosures commonly found in hazardous environments.
The ECLK26 S758 is rated for Class I, Division 1; Class II, Division 1; and Class III locations, under NEC/CEC standards. This means it is suitable for environments with flammable gases, vapors, dust, and fibers, offering enhanced protection against ignition sources. These ratings help with regulatory approvals, safety compliance, and insurance considerations on industrial facilities.
This coupling excels in industries such as oil & gas, chemical processing, mining, and marine applications, where hazardous area classifications and corrosive or moisture-rich conditions are common. Its forged brass construction and PVC coating provide durability, while the 6" flexible segment supports complex routing in equipment rooms, offshore platforms, and downhole installations.
The ECLK26 S758 aligns with NEC/CEC standards and carries hazardous-location ratings Class I, Division 1; Class II, Division 1; and Class III. These certifications support regulatory compliance, enable safer equipment integration, and simplify procurement approvals for projects governed by strict electrical and safety codes in plants, refineries, and shipyards.
Using the ECLK26 S758 can reduce maintenance costs and downtime due to its corrosion resistance and protective PVC coating, which extend service life in harsh environments. The robust brass construction minimizes replace-and-rework cycles, while the flexible design lowers installation time. Together, these factors translate to lower total cost of ownership in hazardous-area conduit systems.
