Eaton Crouse-Hinds ECLK712 coupling - Hazardous Location Class I Div 1
Part Number: ECLK712
Quick Summary
The Eaton Crouse-Hinds ECLK712 coupling is a 12-inch flexible conduit connection designed for hazardous locations. Many installers confront fittings that corrode, leak, or fail to meet NEC/CEC standards in Class I, Division 1 environments, driving maintenance costs and downtime. This coupling delivers NEC/CEC compliance and a hazardous-area rating, while its stainless steel body provides durable, corrosion-resistant performance. With a 2-1/2 inch trade size and a robust 12-inch flexible length, it supports reliable routing in tight plant spaces and demanding offshore or marine installations. By combining field-installability with industry-leading standards, it offers a clear business value: safer installations, longer service life, and reduced lifecycle costs in hazardous locations.
