Eaton Crouse-Hinds LT7590 SA Liquidator - Class I/II
Part Number: LT7590 SA
Quick Summary
LT7590 SA liquidtight connector provides rugged FMC conduit connections for hazardous-location industrial installations. Too often, hazardous-area fittings fail to meet NEC/CEC requirements, driving maintenance costs and downtime. This LT7590 SA meets NEC/CEC standards and hazardous-location approvals with Class I, Division 2; Class II and III ratings. Built from aluminum, non-insulated, and sized for 3/4\" trade connections, it offers lightweight durability, corrosion resistance, and easy installation—reducing field labor time and total cost of ownership for industrial facilities. Engineers will appreciate documented compatibility with FMC fittings, 90° elbow configurations, and adaptability to compact panel spaces. For procurement teams, the aluminum construction provides favorable weight-to-strength and corrosion resistance in oily or humid environments.

FAQs
For installation, mount the LT7590 SA in the desired FMC conduit run, ensuring the 3/4 inch trade size matches the mating fittings. Use appropriate enclosure seals and tighten to standard FMC torque guidelines to maintain ingress protection. Verify compatibility with NEC/CEC requirements and confirm that the site is within Class I/II/III zone classifications before powering the system. This approach minimizes rework and preserves wiring integrity in demanding environments.
The LT7590 SA carries NEC hazardous location ratings including Class I Division 2, Class II Division 1, Class II Division 2, and Class III. These ratings indicate suitability for environments with flammable gases, vapors, dust, and fibers. Selecting this connector helps ensure regulatory compliance, reduces risk of ignition sources, and supports safe operation in chemical plants, oil refineries, and mining facilities where hazardous atmospheres are present.
Key specifications include a 2.13 inch length/depth, 2.13 inch height, and 1.56 inch width, with a weight of 0.25 lb. These compact dimensions support tight panel layouts and predictable space planning in control cabinets, J-boxes, and equipment enclosures. Confirm clearance around mounting bosses and gasketed openings to maintain seal integrity in harsh environments.
LT7590 SA excels in hazardous-location installations needing reliable FMC liquidtight connections at a 90° angle. It is well-suited for chemical processing, oil and gas facilities, mining operations, and other environments requiring NEC/CEC compliance and durable aluminum fittings. It reduces field labor, simplifies routing in confined spaces, and lowers maintenance costs by offering a corrosion-resistant, non-insulated, robust connection.
Eaton provides multiple supporting documents for LT7590 SA, including a specification sheet, CAD drawings, and catalog pages. Certifications and compliance data relevant to hazardous locations are accessible through UL/Canada references and the NEC/CEC standards alignment. For project validation, use the Eaton spec sheet, 3D CAD models, and the original catalog page to verify compatibility with your installation and regulatory requirements.
