Eaton Specification Sheet - ECLK312
12in flexible length provides versatile routing options, enabling shorter installation times and fewer elbows or adapters, which translates to reduced field labor costs and fewer potential leak points in conduit runs. Forged brass construction delivers robust mechanical strength and corrosion resistance, increasing service life in harsh environments such as chemical plants or offshore facilities, while maintaining dimensional stability under vibration and temperature cycling. The 1in trade size aligns with common conduit fittings, streamlining procurement and standardizing field assemblies to minimize inventory complexity. Male one end and female on the opposite end offer installation flexibility, allowing quick in-line joins or convenient repipe work without special adapters. Compliance with NEC/CEC standards and Class I, Division 1 ratings provides regulatory assurance and reduces project risk in hazardous locations. These characteristics support faster commissioning, predictable maintenance intervals, and lower total cost of ownership for explosion-proof conduit connections.
