Eaton LTK12590 Liquidtight Connector - Low Profile
Part Number: LTK12590
Quick Summary
LTK12590 liquidtight connector is designed to seal and route FMC cables in hazardous locations. Engineers often struggle with limited space and fittings that complicate field installation, especially in tight panels. It meets NEC/CEC standards and carries Class I Division 2, Class II Division 1 and 2, and Class III ratings for hazardous locations. Its compact, low-profile design reduces enclosure footprint while delivering reliable sealing for FMC conduit, supporting compliant terminations and faster wiring. Across industrial facilities, this translates to reduced install time, lower labor costs, and fewer field service calls, making it a prudent choice for mission-critical enclosures.

Eaton Specification Sheet - LTK12590
90° angle design reduces the number of elbows and simplifies conduit routing in crowded control panels. The result is faster terminations and a cleaner, more reliable seal for FMC conduit in industrial automation environments. This is especially valuable in machine loops and cabinet interiors where space is at a premium. Malleable iron construction provides robust mechanical strength and high durability, delivering longer service life in challenging factory floors and outdoor installations, while maintaining a compact footprint that supports reliable performance in harsh conditions. Non-insulated construction keeps the fitting simple to install and reduces heat build-up in enclosed spaces, streamlining field terminations without compromising safety. The 1-1/4 inch trade size ensures compatibility with common FMC conduit and enclosure ports, supporting efficient wiring and inventory management for motor control and power distribution teams. Its low-profile form factor enables denser panel layouts, minimizing height and depth requirements while preserving protective grounding paths and sealing integrity. The low-profile design together with standard FMC compatibility helps accelerate installation schedules, lower labor costs, and reduce retrofit complexity in existing facilities. Certification and NEC/CEC alignment reinforce compliance during design reviews and field commissioning, mitigating risk for hazardous location projects and industrial automation deployments. Real-world practice shows that these features translate into measurable gains in installation speed, maintenance intervals, and overall project ROI for end users seeking durable, compliant liquidtight fittings.

FAQs
When installing the LTK12590, ensure mounting is within reach of the FMC conduit run, maintain proper clearance for the 90° bend, and verify enclosure sealing is not compromised by tight routing. Use appropriate strain relief, secure fittings with recommended torque, and align with NEC/CEC guidelines for hazardous locations to maintain certification integrity and long-term reliability.
Yes. The LTK12590 is rated for hazardous locations including Class I Division 2, and also supports Class II Division 1 and 2 and Class III as specified. This makes it appropriate for equipment enclosures in areas with potential flammable atmospheres, helping maintain compliance during design and field installation.
LTK12590 combines a 90° angle with a low-profile malleable iron body and 1-1/4 inch trade size, specifically chosen for tight panel spaces and rugged environments. Its non-insulated construction simplifies terminations while preserving protective sealing for FMC conduit, delivering space savings and robust performance in demanding automation settings.
It supports NEC/CEC standards and hazardous location classifications including Class I Division 2, Class II Division 1 and 2, and Class III. These certifications matter because they validate safe operation in potentially explosive environments, streamline regulatory approvals, and reduce procurement risk for industrial automation projects.
The LTK12590 offers faster install times due to its compact, low-profile design and simplified FMC termination. Space savings enable denser panel layouts, reducing enclosure size and wiring complexity. Combined with verified hazardous-location ratings, this leads to lower ongoing maintenance, fewer field errors, and a faster project timeline with improved total cost of ownership.
