Eaton LTBK20090 Liquidtight Connector - Hazardous/Classified
Part Number: LTBK20090
Quick Summary
Eaton Crouse-Hinds LTK liquidtight connector provides rugged, moisture-tight termination for FMC conduits in hazardous locations. Engineers often fight limited installation space and misalignment during panel builds, which slows projects and increases rework. This high-strength, insulated 90-degree connector helps maintain seal integrity while accommodating tight bends. It meets NEC/CEC standards and offers hazard-rated performance for Class I, Division 2; Class II, Division 1 and 2; and Class III environments, with Canadian certification support. The low-profile design simplifies installations in cramped control panels and equipment rooms, while its malleable-iron construction withstands industrial vibration and temperature variations. In practice, this reduces install time, supports compliance, and lowers long-term maintenance costs in automation deployments.

Eaton Specification Sheet - LTBK20090
Feature: The 90° FMC liquidtight design minimizes bend radius, enabling shorter enclosure runs and neater wiring in automation cabinets. Business impact: faster cabinet builds and fewer rework items due to routing errors in control panels and machines. Application: ideal for tight spaces where conventional fittings would require additional clearance. Feature: Malleable iron construction with an insulated housing delivers rugged mechanical protection and reliable insulation. Impact: improved seal integrity under vibration and temperature swings, reducing failure risk in harsh industrial environments. Application: heavy-duty process lines and outdoor or factory floor installations. Feature: Low-profile footprint reduces protrusion into crowded enclosures. Impact: easier fit with other components, faster assembly, and better space utilization in space-constrained panels. Application: automation cabinets and switchgear with tight clearances. Feature: Area classification support with NEC hazardous ratings Class I Div 2, Class II Div 1/2, and Class III. Impact: ensures regulatory compliance and reduces inspection findings. Application: hazardous-area installations. Feature: 2" trade size with 4.3" length, 3.4" height, 6.7" width and 1.85 lb weight facilitates accurate BOM planning. Impact: simplifies inventory management and field provisioning. Application: assembly lines and service fleets relying on consistent fittings. Insight: Leveraging Eaton Specification Sheet LTBK20090 accelerates correct installation practices and compatibility across the LTK low-profile family.
