Eaton LTBK3890 Liquidtight Connector - Hazardous Locations
Part Number: LTBK3890
Quick Summary
LTBK3890 liquidtight connector is a reliable FMC fitting for hazardous-location conduit systems. Engineers often struggle with compact, compliant fittings that don’t sacrifice durability. This product carries NEC/CEC compliance and hazardous-location ratings including Class I Division 2, Class II Division 1, Class II Division 2, and Class III. The low-profile design paired with insulated malleable iron construction reduces installation space in crowded panels while delivering robust protection for 3/8" trade-size FMC runs. For maintenance teams, this translates into quicker retrofits, less panel cutting, and lower total cost of ownership across chemical, oil and gas, and power utility applications.

Eaton Specification Sheet - LTBK3890
90° elbow design enables tight routing with a reduced enclosure footprint, accelerating panel assembly and serviceability in restricted spaces. This translates to measurable efficiency gains on large installations and retrofit projects where space is at a premium in control cabinets and field enclosures. The malleable iron construction, combined with insulation, provides durable, corrosion-resistant protection in harsh environments, enhancing safety and extending component life in chemical plants and mining operations. The low-profile profile reduces overall enclosure intrusion, streamlining wiring layouts and enabling faster commissioning for new systems or upgrades. The 3/8" trade size aligns with common FMC conduit standards, improving compatibility and reducing inventory complexity for procurement teams. NEC/CEC compliance and the explicit hazardous-location ratings ensure regulatory confidence, simplifying audits and minimizing design-resubmission risk in regulated facilities. Overall, the LTBK3890 delivers reliable performance with installation- and maintenance-friendly characteristics that support total cost of ownership reductions.
