Appleton exgjh-127 Flex Conduit Coupling 1/2 in 27 in

Product Description

The APPLETON exgjh-127 is a heavy-duty explosionproof flexible conduit coupling designed for use in hazardous and wet locations. The coupling features a natural-finish bronze outer braid and a brass inner core with an insulating liner, providing both mechanical protection and electrical isolation. It measures 27 inches in flex length with a 1/2 inch trade size and includes two removable male nipples for connection to threaded rigid metal conduit or IMC. The 10-inch bending radius and watertight construction make it suitable for demanding industrial environments where conduit vibration and movement must be accommodated without compromising enclosure integrity. Licensed electricians and industrial maintenance technicians are the primary installers.

This flexible coupling is rated for Class I Division 1 and 2 Group A B C D, Class II Division 1 and 2 Group E F G, Class I Zone 1 and 2 Group IIA IIB IIC, and Class III enclosures, covering a broad range of flammable gas, vapor, and combustible dust hazard classifications. It is approved for use on threaded rigid metal conduit and IMC, making it a direct fit for conduit runs in oil refineries, chemical processing plants, grain handling facilities, paint spray areas, and similar NEC and CEC-governed hazardous locations. The ambient temperature rating spans -40 to 302 degrees F, supporting extreme environment service.

Key Features

• Explosionproof and dust-ignitionproof construction rated for Class I, II, and III hazardous locations
• Bronze outer braid with natural finish provides flexible, durable mechanical protection
• Brass inner core with insulating liner isolates grounding paths and prevents galvanic issues
• Watertight design suitable for wet location conduit installations
• 27-inch flex length with a 10-inch bending radius accommodates equipment vibration and misalignment
• Includes two removable male nipples for connection to threaded rigid metal conduit and IMC
• Ambient temperature range of -40 to 302 degrees F supports extreme industrial environments

Compatibility

Designed for use on threaded rigid metal conduit and IMC at 1/2 inch trade size. Listed under UL 886 and CSA C22.2 for Class I Division 1 and 2 Group A B C D, Class II Division 1 and 2 Group E F G, Class I Zone 1 and 2 Group IIA IIB IIC, and Class III enclosures. Applicable standards include NEC and CEC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 501 and applicable CEC requirements for hazardous location wiring. De-energize and lock out the circuit before removing or installing any conduit fittings. Hand-tighten the male nipples into conduit threads first, then use appropriate conduit wrenches to achieve a secure, watertight connection. Do not overbend below the minimum 10-inch bending radius, as this can damage the braid or compromise the explosionproof rating.
