Eaton Specification Sheet - ECLK327
Forged brass construction provides enhanced corrosion resistance and mechanical strength, delivering long service life in harsh environments. This translates to reduced replacement cycles and lower maintenance costs on offshore platforms and chemical plants. The result is a more reliable conduit connection that stays sealed and intact under vibration and exposure to salt spray. 1 inch trade size offers standard interfacing with common conduit systems, minimizing the need for adapters and simplifying procurement. The male/female endings support quick field assembly, reducing installation time and training requirements for technicians working in hazardous zones. A 27 inch flexible segment combined with a 32 inch overall length gives routing versatility around equipment and obstacles, lowering installation labor while preserving integrity. NEC/CEC compliance and Class I, Division 1 ratings ensure regulatory acceptance in North America, while Hazardous/Classified Location approval reduces compliance risk for maritime and chemical facilities. Together these features result in improved uptime, reduced lifecycle cost, and safer, Code-compliant installations across industries such as oil & gas, chemicals, and offshore wind.
