Eaton LTBK125 Liquidtight Connector - Low Profile
Part Number: LTBK125
Quick Summary
Eaton LTBK125 Liquidtight Connector provides rugged FMC sealing for hazardous-location electrical enclosures. Engineers often struggle with tight spaces and complex routing that slow installs and raise the risk of leaks. This low-profile, insulated steel connector is designed for NEC/CEC compliance and hazardous-location ratings, including Class I Division 2 and Class II/III classifications, simplifying approvals. By combining a compact footprint with a dependable seal, it reduces field rework and accelerates panel assemblies in industrial automation and power distribution. With a 1-1/4 inch trade size and straight configuration, it streamlines routing through compact panels, while its robust construction supports demanding environments. Operational cost is lowered through easier maintenance and fewer component changes over the life of the installation.

FAQs
The LTBK125 is designed specifically for FMC conduit with a 1-1/4 inch trade size and a straight configuration. During installation, align the connector with the conduit, secure it to the enclosure, and use the recommended seals per Eaton’s specification sheet. This reduces leakage risk, speeds panel assembly, and improves reliability in tight spaces common to automation and control panels.
LTBK125 supports NEC/CEC compliance and hazardous-location ratings including Class I Division 2, Class II Division 1 and 2, and Class III, with area classifications for hazardous or classified locations. The insulated steel construction enhances durability and thermal resilience, helping maintain a reliable seal under challenging industrial conditions and facilitating regulatory approvals for global deployments.
Yes. The LTBK125 features a low-profile design combined with a straight 1-1/4 inch trade-size configuration, making it ideal for space-constrained panels. Its compact footprint supports closer component placement and easier routing in automation cabinets, reducing enclosure depth requirements while maintaining robust sealing against moisture and dust in FMC conduit installations.
LTBK125 meets NEC/CEC standards and hazardous-location ratings (Class I Division 2, Class II Division 1 and 2, Class III) with area classifications. It is compatible with UL-listed Canadian certifications and Eaton catalogs, enabling safer cross-border deployments without rework and aiding procurement across multinational facilities.
The LTBK125 offers faster panel builds due to its straight, low-profile design and reliable sealed connection, reducing labor costs and field rework. Its durable steel insulation resists harsh environments, extending service life and lowering maintenance downtime. Overall, it translates to lower total cost of ownership in automated production lines and heavy-industry facilities.
