Eaton Crouse-Hinds ECLK515 Coupling - Hazardous Locations
Part Number: ECLK515
Quick Summary
ECLK515 is a rugged, flexible-length coupling for hazardous locations used in industrial conduit systems. Designers often struggle with bulky installs, leaks in challenging environments, and slow retrofits in Class I/II areas. It meets NEC/CEC standards and hazardous-location classifications including Class I, Division 1, Class II, Division 1, and Class III, helping secure regulatory compliance on day one. The forged-brass construction and 15-inch flexible length with a 1-1/2-inch trade size deliver dependable performance, simplify sourcing, and reduce lifecycle costs for explosion-proof installations in chemical plants, refineries, and offshore facilities.
