Eaton Crouse-Hinds LTK3890 Liquidtight Connector - Low Profile FMC 90° Hazardous/Classified Locations
Part Number: LTK3890
Quick Summary
LTK3890 liquidtight connector is designed for secure, high-integrity cable management in hazardous/classified locations within industrial facilities. This 90° FMC connector addresses space constraints and tight routing challenges that frustrate installation teams, helping prevent strain on conduits and cables. It carries NEC/CEC approvals with hazardous-location ratings including Class I, Division 2; Class II, Division 1 and 2; and Class III, delivering compliant performance in dusty or damp environments. The low-profile, malleable-iron construction provides rugged durability without bulky bulkhead fittings, reducing panel footprint. By pairing a non-insulated connector with a 3/8\" trade size, it streamlines field wiring and inventory management, while ensuring reliable sealing and mechanical integrity across demanding industrial applications.

Eaton Specification Sheet - LTK3890
The 90° FMC liquidtight connection enables clean, right-angle routing in tight equipment enclosures, reducing the need for extra elbows and adapters. This translates to shorter install times and fewer leak points, improving system integrity in critical applications such as motor starters and PLC cabinets. Low-profile geometry minimizes panel footprint and crosstalk with nearby wiring, enabling denser terminations without sacrificing seal performance. In practice, technicians appreciate faster field sealing and less space required for grommets and clamps in congested panels. Constructed from malleable iron and designed for non-insulated use, the LTK3890 withstands vibrations and harsh environments common in industrial settings. Its rugged construction supports long service life in hazardous locations while reducing maintenance cycles. Trade size 3/8\" aligns with common FMC cables used in automation equipment, enabling direct compatibility with existing fittings and reducing the need for adapters. The connector’s 90° angle also simplifies cabling routes in tight machines, cutting installation time. Compliance is built-in with NEC/CEC standards and explicit hazardous-location ratings (Class I, Division 2; Class II, Division 1/2; Class III), helping your team pass audits and avoid costly rework. The low-profile, non-insulated design further supports quick wiring and traceability.

FAQs
LTK3890 is designed for FMC conduit with a 3/8\" trade size in right-angle configurations. It mates with standard FMC housings, provides a 90° turn, and accepts typical sealing practices used with Eaton Crouse-Hinds fittings. This makes it ideal for panel-to-cabinet runs and equipment enclosures where space constraints require compact, right-angle terminations.
The 90° angle reduces the need for additional elbows and adapters, cutting overall installation time and labor costs. It also minimizes bundle clutter inside control panels, improving wire routing clarity and seal integrity in tight spaces around motor starters, drive controllers, and PLC cabinets.
Yes. The LTK3890 carries NEC hazardous-location ratings including Class I, Division 2, and is listed under NEC/CEC compliance. This makes it appropriate for equipment installed in areas with restricted or hazardous atmospheres, ensuring safer terminations and easier regulatory audits.
LTK3890 is certified under NEC/CEC standards for hazardous locations and is rated for Class I, Division 2; Class II, Division 1; Class II, Division 2; and Class III. This certification supports compliance in industrial facilities and helps reduce rework during inspections or audits.
The rugged malleable-iron body and low-profile design deliver durable performance with fewer failure points, lowering maintenance needs in harsh environments. Right-angle routing reduces installation time and materials while improving enclosure density, contributing to lower total cost of ownership and faster project ROI for automation and electrical upgrade programs.
