Feature: 90-degree Liquidator connector provides precise FMC conduit routing, enabling cleaner bends and consistent enclosure spacing. Business Impact: reduces misalignment, minimizes leak paths, and shortens installation time in dense electrical racks. Application: ideal for control panels, motor control centers, and instrumentation enclosures in chemical plants, refineries, and other hazardous environments. Feature: Malleable iron, non-insulated housing delivers rugged mechanical strength and resilient service life. Business Impact: stands up to vibration, temperature swings, and splash exposure common in industrial floors, reducing repair frequency and maintenance costs. Application: outdoor installations, wash-down zones, and process areas where durability matters. Feature: 4-inch trade size and a compact footprint accommodate large conductors with fewer fittings. Business Impact: simplifies bill of materials, lowers inventory variety, and accelerates field commissioning for mid- to high-current FMC runs. Application: large electrical cabinets and high-density conduit layouts in hazardous-area installations. Feature: NEC/CEC compliance and hazardous-location ratings including Class I Division 2, Class II Division 1–2, and Class III ensure regulatory alignment and safer operations. Business Impact: reduces certification overhead, eases procurement decisions, and supports plant-wide safety programs. Application: petrochemical, mining, and heavy manufacturing facilities requiring formal compliance in liquidtight fittings. Feature: Availability of engineering resources such as 3D CAD drawings, catalogs, UL certifications, and specification sheets speeds design validation and downstream BOM accuracy. Business Impact: shortens engineering cycles, improves procurement confidence, and minimizes late-stage changes. Application: design offices, procurement, and maintenance teams seeking reliable, code-compliant liquidtight fittings.
