Killark Flex Coupling Bronze 1/2in 18in ECFUF-118

Hazardous-Location Flex Coupling

This bronze flex coupling is rated for Class I Division 1 and 2, Groups A through D, Class II Division 1 and 2, Groups E through G, and Class III hazardous locations. It connects rigid conduit runs where vibration or movement requires a flexible link. Electrical contractors and maintenance teams use it in refineries, chemical plants and grain-handling facilities.

Eighteen-Inch Flexible Length

The assembly provides an 18 in flex length and an overall length of 24 1/8 in, giving enough reach to bridge misaligned conduit ends or absorb equipment vibration. The bronze hose with steel union handles repeated flexing in corrosive atmospheres. It is not suited for runs that require a longer flexible section or for non-hazardous general-purpose wiring where a simpler fitting would suffice.

Half-Inch NPT Ends Bronze Construction

Ends are 1/2 in FNPT female by 1/2 in MNPT male, allowing direct threading into existing conduit bodies or enclosures without adapters. Bronze material resists corrosion in wet or chemical environments while the steel union adds mechanical strength. The 2 1/16 in overall height and width fit within standard conduit-body profiles, though installers should verify clearance in tight junction boxes.
