Eaton Crouse-Hinds LTK50 Liquidtight - Low Profile
Part Number: LTK50
Quick Summary
LTK50 liquidtight connector delivers rugged FMC wiring for hazardous locations in industrial plants. Engineers often struggle with sealing integrity, installation time, and maintaining electrical safety when upgrading legacy feeds in harsh environments where moisture, dust, and vibration are common. This connector is certified for NEC/CEC compliance and hazardous-location ratings, including Class I, Division 2; Class II, Division 1 & 2; and Class III, supporting broad industrial applicability. With a compact, low-profile steel body and non-insulated construction, it enables faster, more reliable terminations while reducing enclosure footprint and long-term maintenance costs for cost-conscious modernization projects.

FAQs
Yes. The LTK50 is a straight liquidtight connector designed specifically for FMC conduit and 1/2 inch trade size. Its steel, non-insulated body provides a robust termination suitable for hazardous locations, and it installs with standard FMC practices in NEC/CEC-compliant panels. Always follow torque and sealing guidelines per the Eaton specification sheet for optimal performance.
LTK50 carries NEC/CEC standards support and hazardous location ratings, including Class I, Division 2; Class II, Division 1; Class II, Division 2; and Class III. These ratings ensure safe operation in classified environments such as chemical plants, refineries, and mining sites, while maintaining reliable electrical continuity and environmental sealing.
LTK50 is well-suited for industries with harsh environments and space constraints, such as chemical processing, oil and gas, mining, and heavy manufacturing. The 1/2 inch FMC straight connector with a low-profile steel body excels in control panels, junction boxes, and equipment feeds where quick terminations and durable protection against dust, moisture, and vibration are required.
Compliance is supported by NEC/CEC standards and hazardous-location ratings listed in the product catalog and certification pages. For Canada, UL-based certification reports confirm suitability for Class I/II/III environments. The Eaton LTK low-profile catalog page and U.L. listings provide the official documentation needed for audit trails and regulatory filings.
The LTK50’s low-profile steel construction and 1/2 inch FMC compatibility reduce enclosure space and installation time, cutting labor costs in large installations. Its durable materials lower replacement frequency in harsh settings, improving uptime and long-term return on investment. Expect streamlined terminations, easier field routing, and consistent performance across hazardous locations.
