Eaton Specification Sheet - ECLK512 S758
Feature → Business Impact → Application: The ECLK512 S758 uses a forged brass body with a flexible PVC protective coating, delivering superior corrosion resistance and longevity in harsh environments, reducing maintenance cycles and total cost of ownership for hazardous-area conduit systems used in oil, gas, and chemical plants. This enables easier field assembly and robust performance in tight or awkward install spaces, minimizing downtime during commissioning. Feature → Business Impact → Application: A 12" flexible section combined with a 1-1/2" trade size supports rapid rerouting and reliable sealing in constrained conduit runs, increasing installation speed by reducing cut-and-fit workflows and enabling safer, code-compliant installations in aircraft hangars, shipyards, and refineries. Feature → Business Impact → Application: Male and female ends on both sides simplify mating with existing fittings, improving compatibility across EC explosion-proof couplings and reducing the need for adapters, which lowers inventory complexity and accelerates project timelines in hazardous-location projects. Feature → Business Impact → Application: Forged brass with flexible PVC coating provides a durable, moisture-resistant exterior that stands up to outdoor, offshore, and underground environments, improving reliability in corrosion-prone zones and supporting long-term performance guarantees demanded by facilities managers and automation engineers. Feature → Business Impact → Application: NEC/CEC compliance and explicit Class I Division 1 (and Class II Division 1, Class III) ratings give procurement teams confidence in regulatory alignment, enabling faster approvals, reducing audit findings, and supporting safer operation in industrial automation and marine equipment applications.

FAQs
The ECLK512 S758 provides a 1-1/2 in trade size with male and female ends and a 12 in flexible section. Ensure mating with compatible conduit fittings, confirm the installation path accommodates the 18.63 in overall length, and follow NEC/CEC guidelines for Hazardous/Classified Locations. The flexible PVC coating adds moisture resistance, simplifying outdoor or marine deployments.
This coupling is listed for Hazardous/Classified Locations under NEC/CEC standards and carries NEC hazardous ratings for Class I Division 1 (with additional Class II Division 1 and Class III as noted). Canadian certification and UL-related documents are available, reinforcing compliance across North American hazardous-location applications.
Ideal for oil and gas facilities, chemical processing plants, offshore platforms, mining operations, and marine environments where durable, explosion-proof conduit connections are required. Its forged brass body and PVC coating provide corrosion resistance, while the 12" flexible section supports challenging installations without compromising safety or performance.
The combination of a 12" flexible section, dual-ended male/female connections, and a 1-1/2" trade size streamlines field assembly. The forged brass construction plus flexible PVC coating enhances durability and environmental resistance, reducing maintenance frequency and lifecycle costs while ensuring regulatory compliance in hazardous locations.
Expect lower maintenance due to corrosion-resistant forged brass and PVC-coated protection, which extend service intervals in harsh environments. Regulatory compliance reduces audit findings and rework, contributing to a favorable total cost of ownership for projects in hazardous locations and long-term asset performance.
