Feature 1: 21" flexible length provides route flexibility and reduces the number of fittings in long conduit runs, improving installation speed and reducing material waste. Business impact: faster project completion and lower material costs in hazardous-area installations; Application: shipyards, refineries, or offshore platforms where tight space and complex routing are common. Feature 2: Male connections on both ends simplify field assembly and daisy-chaining of conduit runs, lowering labor time and error potential; Application: continuous runs in restricted spaces. Feature 3: Forged brass construction delivers mechanical strength and corrosion resistance in humid or chemical-service areas, improving long-term reliability and maintenance intervals. Feature 4: Flexible PVC protective coating guards against moisture ingress, chemical exposure, and abrasion, extending service life in marine and onshore facilities. Feature 5: 1-1/4" trade size ensures compatibility with standard conduit systems, supporting interoperability with Eaton Crouse-Hinds EC explosionproof fittings and existing inventories. Certifications: NEC/CEC compliance with Class I, Division 1; Hazardous Locations rating improves safety and reduces regulatory risk.

FAQs
Begin by verifying conduit size and placement, ensure proper cleaning of mating surfaces, and tighten male-end connections using standard torque per conduit fittings. The 1-1/4" trade size and 21" flexible length reduce field joints, while the flexible PVC coating protects against moisture and chemicals in Class I, Division 1 environments.
The coupling complies with NEC/CEC standards and is rated for Hazardous Locations, including Class I, Division 1 (and II, Division 1) and Class III. This ensures regulatory alignment for industrial, marine, and chemical processing facilities.
Yes. It features a 1-1/4" trade size and male-to-male ends, designed to integrate with Eaton Crouse-Hinds EC explosionproof fittings and typical conduit runs in hazardous environments.
The coupling uses forged brass for strength and corrosion resistance, with a flexible PVC protective coating to resist moisture, abrasion, and chemical exposure common in hazardous locations.
The combination of a 21" flexible length, robust brass construction, and protective PVC coating minimizes field joints and wear, simplifying installation and lowering maintenance frequency in challenging environments such as refineries and offshore platforms.
