Eaton Specification Sheet - ECLK536 S758
36-inch flexible length provides routing versatility in constrained spaces, enabling faster alignment and reduced labor time during installation and maintenance, especially in complex conduit runs. The design, featuring male on one end and female on the other, simplifies splicing and equipment hookups, cutting field coordination time and minimizing downtime in critical processes. Forged brass offers superior mechanical strength and corrosion resistance in chemical, offshore, and heavy-industrial environments, delivering extended service life and lower replacement costs. The flexible PVC coating adds moisture and chemical protection, reducing ingress risks and protecting internal conductors without sacrificing flexibility or ease of handling. A 1-1/2-inch trade size ensures compatibility with a broad range of standard conduit systems, streamlining inventory management and procurement for OEMs and maintenance teams. NEC/CEC compliance and Class I, Division 1 ratings provide regulatory assurance, enabling safe operation in hazardous locations and supporting audits and inspections. The overall build weight and robust construction improve on-site handling and reduce installation fatigue for technicians, providing a reliable conduit connection solution with lower total cost of ownership.

FAQs
For hazardous locations, ensure proper mating between the male and female ends to achieve a tight, vibration-resistant fit. Validate the 1-1/2 inch trade-size conduit compatibility and verify that the protective PVC coating is intact to resist moisture ingress. Follow the NEC/CEC guidelines for conduit fittings in Class I, Division 1 environments and use UL-certified components where applicable to maintain compliance and performance over the lifecycle.
Yes. The ECLK536 S758 is listed for NEC/CEC compliance with Class I, Division 1 ratings, and UL certifications for hazardous locations. This combination supports regulatory compliance, safer installations, and easier qualification during routine audits, making it suitable for chemical plants, refineries, and other high-risk facilities.
This coupling is ideal for long runs and tight routing in hazardous areas, including chemical processing, oil and gas facilities, and offshore platforms. Its 1-1/2 inch trade size and 36-inch flexible length support versatile layouts, while the brass core and PVC coating deliver durability under moisture, dust, and chemical exposure typical of industrial environments.
Key specs include a 1-1/2 inch trade size, 36-inch flexible length, and overall robust dimensions designed for industrial conduit systems. The unit weighs approximately 25.05 lb and features forged brass construction with a flexible PVC protective coating for corrosion and moisture resistance, suitable for hazardous-location installations.
The flexible PVC coating provides enhanced moisture and chemical resistance, reducing ingress risks and protecting the brass core from corrosion. This translates to longer service life in harsh environments and lower maintenance costs, because fewer replacements and patch repairs are needed in demanding facilities such as refineries and offshore installations.
