Eaton Crouse-Hinds LTK7590 Liquidtight Connector - Hazardous
Part Number: LTK7590
Quick Summary
LTK7590 liquidtight connector is designed for rugged FMC terminations in hazardous-location equipment across industrial facilities. Installers often struggle with restricted spaces and complex routing, making reliable sealing essential; this low-profile solution speeds assembly while preserving enclosure integrity. It carries NEC/CEC compliance and area classifications for Hazardous/Classified Locations, plus Canadian certification, supporting multinational projects. With malleable iron construction and non-insulated, low-profile design, it minimizes enclosure intrusion while delivering strong mechanical performance. For OEMs and integrators, the result is faster commissioning, reduced field labor, and safer, durable terminations in harsh environments. This combination aligns with key industry standards and streamlines ongoing maintenance.

Eaton Specification Sheet - LTK7590
Feature: 90° FMC liquidtight connector design enables tight routing around corners in control panels, reducing wiring stress and enclosure gaps. Business Impact: Improves reliability and reduces installation time by allowing shorter wiring runs and fewer adapters. Application: Suitable for machine tools, chemical processing, and hazardous-location equipment where space is constrained. Feature: Low-profile, malleable iron body with non-insulated construction provides durable protection while minimizing enclosure intrusion. Business Impact: Frees panel space and simplifies mounting, lowering assembly complexity and downtime. Application: Enclosures with tight tolerances and limited depth in manufacturing lines or process facilities. Feature: 3/4 inch trade size with FMC compatibility ensures straightforward substitution and standardized installations. Business Impact: Reduces inventory variety and maintenance costs, facilitating rapid replacement during uptime-critical projects. Application: Retrofit and new-builds requiring common FMC fittings. Feature: NEC/CEC conformance and hazardous-location ratings (Class I, Division 2; Class II, Division 1/2; Class III) plus area classifications. Business Impact: Ensures code compliance across regions, lowering non-compliance risk and inspection delays. Application: Global projects with mixed regulatory environments in mining, water treatment, and packaging. Feature: Compact weight and dimensions (0.31 lb, 1.78 in L, 2.91 in H, 2.81 in W) provide predictable handling and easy installation. Business Impact: Improves field efficiency and reduces labor time for panel penetrations. Application: OEM assemblies and serviceable equipment in constrained electrical rooms.

FAQs
The LTK7590 is a 3/4 inch trade size FMC liquidtight connector designed for hazardous-location terminations. It features a 90° angle, malleable iron body, and non-insulated construction, ensuring reliable sealing and mechanical strength in Class I, Division 2; Class II, Division 1/2; and Class III environments. It integrates with standard FMC systems and fits common panel routing without additional adaptors, reducing installation time and stock variety.
The 90° angle facilitates corner routing and tight-space terminations, minimizing enclosure depth and reducing wiring stress from sharp bends. This improves wiring organization, speeds commissioning, and lowers the risk of damage during field modifications. In harsh environments, the 90° connector also helps maintain secure seals where space constraints would otherwise force awkward connections.
Yes. The LTK7590 carries NEC hazardous-location ratings for Class I, Division 2; Class II, Division 1 and 2; and Class III, along with area-classification certification. This makes it suitable for hazardous locations in mining, chemical processing, and heavy manufacturing, ensuring compliance across installed bases and reducing the likelihood of non-conformance during audits.
The LTK7590 is certified under NEC/CEC standards and area classifications for Hazardous/Classified Locations, with Canadian certification references. These certifications back universal, code-compliant installs, simplify cross-border projects, and minimize rework after inspections. The UL/ULC lineage also provides confidence in long-term reliability and safety for critical process equipment.
Plan routing to exploit the low-profile design, reducing enclosure penetration counts and panel depth. Use the 3/4 inch FMC fitment to standardize terminations across machines, duplicate fittings for spares, and verify all seals for hazardous location compliance. By trimming installation time and minimizing field adjustments, maintenance costs drop while uptime improves in continuous-operation environments.
