Eaton Crouse-Hinds ECLK1033 coupling - Class I, Division 1
Part Number: ECLK1033
Quick Summary
The Eaton Crouse-Hinds ECLK1033 coupling provides a flexible, stainless steel conduit connection for hazardous locations. In demanding environments, installers often struggle with rigid fittings that don’t route cleanly or seal reliably in tight spaces. This coupling addresses those challenges with a 33" flexible length and dual-ended gender (male on one end, female on the other) that simplifies routing and reduces installation time. It carries NEC/CEC compliance and hazardous-area ratings including Class I, Division 1, helping ensure regulatory conformity. For engineers and procurement teams, the combination of corrosion resistance, electrical integrity, and a compact footprint translates into lower maintenance costs, improved uptime, and safer, more reproducible installations in chemical plants, offshore facilities, and other hazardous environments.

FAQs
The ECLK1033 coupling is designed for use in hazardous environments with a stainless steel body and a 33" flexible length. Installers should verify Class I, Division 1 compliance and NEC/CEC standards, ensure proper male/female end alignment, and follow manufacturer torque and sealing recommendations to maintain explosion-proof integrity and prevent ingress in confined spaces.
Yes. The ECLK1033 carries NEC/CEC compliance with Class I, Division 1 ratings, making it suitable for hazardous locations. It also benefits from UL certifications for explosion-proof performance. When selecting, confirm the site’s classification and ensure that the 4" trade size and 33" flexible length meet the conduit routing requirements.
The ECLK1033 measures 42.25 inches in length with a height of 4.94 inches and a width of 4.94 inches. It weighs 0.1 pounds and features a 33-inch flexible portion coupled with a 4-inch trade size, enabling adaptable installation across varied conduit layouts.
The ECLK1033 is built to NEC/CEC standards and Class I, Division 1 ratings, with UL certifications for explosion-proof performance. It is intended for Hazardous/Classified Locations, including environments requiring robust corrosion resistance and reliable sealing, helping meet regulatory requirements and safety audits.
The stainless steel construction resists corrosion in tough environments, while the 33" flexible length allows easier routing and fewer joints, reducing leak points and potential failure. Its compliant design and dual-end connections minimize rework during maintenance, delivering longer service intervals and more predictable performance in demanding industrial settings.
