Eaton LTBK15090 Liquidtight Connector - Low Profile 90° FMC
Part Number: LTBK15090
Quick Summary
LTBK15090 is a liquidtight connector designed for FMC conduit in hazardous locations. In tight panel spaces and complex equipment layouts, installation reliability and weatherproofing often become chokepoints. It meets NEC/CEC standards and hazardous-location ratings such as Class I Division 2; Class II Division 1 and 2; Class III, ensuring safe operation in oil, gas, and chemical plants. Its low-profile form factor and rugged malleable-iron body deliver space-saving protection, while the insulated construction helps maintain integrity in challenging environments. For engineers and procurement teams, this combination translates to faster installs, fewer field failures, and easier compliance across projects.

FAQs
When installing the LTBK15090, ensure proper FMC conduit prep, gasket seating, and secure mounting to maintain a tight seal in hazardous locations. The 90° angle and low-profile body require precise alignment to prevent looseness and ensure long-term moisture and dust exclusion in compact panels.
Yes. The LTBK15090 carries NEC/CEC compliance with hazardous-location ratings including Class I Division 2, Class II Division 1/2, and Class III. These ratings support safe operation in regulated industrial environments and align with North American codes for hazardous areas.
LTBK15090 is specified for 1-1/2 inch trade size FMC conduit, and is designed to integrate with standard FMC fittings and accessories. This minimizes the need for adapters and simplifies sourcing, reducing install time on the shop floor and in the field.
The low-profile design saves panel depth, improves gasket seating, and reduces interference with doors and hardware. This translates to easier maintenance, faster assembly in dense control panels, and fewer clearance-related failures during service or upgrades.
Durable protection against dust, moisture, and hazardous exposure lowers field faults and downtime. The 1-1/2" size plus NEC/CEC compliance simplifies spare parts and regulatory alignment across sites, contributing to a lower total cost of ownership and a quicker return on investment for multi-site deployments.
