Eaton Crouse-Hinds ECLK133 Coupling - Hazardous Locations
Part Number: ECLK133
Quick Summary
Eaton Crouse-Hinds ECLK133 coupling is a flexible explosion-proof conduit connector for hazardous locations. In challenging installations, space constraints and long conduit runs can complicate safe terminations and increase leakage risk. This coupling meets NEC/CEC standards and UL certification for explosion-proof performance, with a Class I, Division 1 rating across major hazardous-location classes. It also supports rugged marine and industrial environments with forged brass construction and a 33-inch flexible lead. For contractors and maintenance teams, this design helps reduce downtime and ensures ongoing compliance when wiring in Class II and Class III zones. Leveraging 1/2-inch trade-size conduits and robust sealing, it delivers safety and lifecycle cost benefits for harsh-duty applications.
