Eaton Specification Sheet - LT7590NM
90° elbow design with a 3/4 in trade size streamlines conduit routing in confined panels, reducing bending and installation time. This improves field productivity and minimizes misalignment that can lead to leaks or stress on fittings. It’s well suited for control panels, motor controllers, and equipment enclosures using FMC conduit in industrial settings, including hazardous locations. Nylon body delivers lightweight handling while resisting environmental moisture and many chemicals, supporting longer service life in tough plants. The material choice also simplifies torque control and reduces tool wear during assembly. This combination is especially advantageous in high-traffic installations like packaging lines, material handling, and process automation where quick, repeatable fittings matter. Conduit compatibility with FMC fittings minimizes the need for adapters and third-party components, accelerating procurement and reducing assembly steps. The non-metallic construction enhances resistance to corrosion and galvanic issues in damp or chemically aggressive environments. This fits seamlessly with Eaton’s non-metallic liquidtight fittings catalog for a streamlined bill of materials. Hazardous/Classified Locations ratings and NEC/CEC compliance provide regulatory alignment and safer operation in potentially explosive atmospheres. Class I, Division 2; Class II, Division 1/2; Class III designations ensure the product is appropriate for a wide range of industrial hazards. This helps OEMs and integrators pass approvals and reduces project risk when specifying fittings for hazardous-area panels. UL certification support for non-metallic liquidtight fittings reinforces product legitimacy and supplier confidence. The LT7590NM also aligns with Eaton’s specification sheet and catalog page, giving engineers a single source of truth for installation guidance, performance expectations, and field maintenance planning. From faster installation to lower maintenance costs, the LT7590NM delivers measurable ROI in automation projects. Its 3/4 in size, 90° geometry, and nylon body balance ease of use with robust sealing, supporting reliable, code-compliant connections across multiple facilities.
