Eaton LTBK7590 Liquidtight Connector - Low Profile
Part Number: LTBK7590
Quick Summary
LTBK7590 is a liquidtight connector designed for FMC conduit applications in hazardous and classified locations. In field projects, installers often struggle with bulky fittings that hinder access and staging under tight clearances. This low-profile, 90° angle fitting reduces enclosure footprint and simplifies routing in crowded panels and junction boxes. It carries NEC/CEC conformity and includes Hazardous/Classified Locations ratings, with Class I, Division 2 and Class II/III provisions, plus Canadian certification options. By combining compact geometry with robust malleable iron construction, it delivers durable protection while streamlining inventory and labor. Use cases include control panels, motors, and process equipment where space is at a premium and reliability is non-negotiable.

FAQs
LTBK7590 is certified for Hazardous/Classified Locations with NEC hazardous ratings including Class I, Division 2, Class II Division 1 and 2, and Class III. It also aligns with NEC/CEC standards and offers Canadian certification options, making it suitable for cross-border industrial deployments in chemical plants, refineries, and other demanding environments.
Yes, the LTBK7590 is a 3/4 inch trade-size FMC liquidtight connector. It features dimensions of 1.78 in (length) × 2.91 in (height) × 2.81 in (width) and weighs approximately 0.36 lb, providing a compact, robust fitting for space-constrained installations.
The low-profile profile reduces the mounting footprint on enclosures and panels, enabling easier routing of FMC conduit in crowded control cabinets and retrofit projects. This translates to faster assembly, simplified wiring management, and reduced risk of interference with nearby components.
Install the LTBK7590 by aligning with the FMC conduit, securing with compatible fittings, and ensuring proper enclosure sealing per NEC/CEC guidelines. Verify Class I, II, III ratings are appropriate for the site, and confirm any Canadian certification requirements for regional use. Ensure torque and sealing specifications are followed to maintain integrity in moisture-prone environments.
The LTBK7590 reduces field labor with its straightforward 90° mating and compact form factor, lowering installation time and inventory counts for hazardous-location projects. Its durable malleable iron construction and insulated body resist environmental wear, reducing maintenance cycles and lifecycle costs while improving reliability in harsh industrial settings.
