Eaton Crouse-Hinds LTB150DC Liquidtight Connector - Hazardous
Part Number: LTB150DC
Quick Summary
LTB150DC is a straight, liquidtight connector for FMC conduits used in hazardous-location electrical installations. Field projects often struggle with moisture ingress, certification gaps, and difficult terminations in tight spaces; this connector mitigates those pain points with a robust zinc die cast body and an insulated seal that simplifies installation. Key certifications include NEC/CEC compliance and hazardous-location ratings, specifically Class I Division 2; Class II Division 1 and 2; Class III, aligning with stringent industry requirements. Beyond compliance, the product delivers predictable performance and reduced maintenance, while remaining compatible with standard FMC fittings and 1-1/2 inch trade size for scalable, repeatable installations in harsh environments.

FAQs
The LTB150DC is a straight, insulated FMC connector with a 1-1/2 inch trade size and a zinc die-cast body. When installing, align the FMC conduit precisely, ensure the gasket/seal seats properly, and follow NEC/CEC guidelines for hazardous locations. Use the recommended torque on the coupling and verify complete enclosure integrity to prevent ingress. This approach minimizes rework and maintenance later in the life of the installation.
LTB150DC is designed for hazardous/classified locations, with NEC/CEC compliance and ratings including Class I Division 2, Class II Division 1, Class II Division 2, and Class III. This means it supports safe operation in environments with flammable gases, flammable dust, and other hazardous conditions. The combination of inspection-ready documentation and tested performance helps ensure regulatory satisfaction and safer installations.
Yes. The LTB150DC is a straight, 1-1/2 inch trade size connector built to integrate with standard FMC conduits and fittings. Its insulated zinc die-cast body is designed to mate with conventional FMC components, enabling straightforward retrofits and new installations. This compatibility reduces sourcing complexity and supports faster commissioning in automation panels and field junctions.
Certification and datasheet resources are available through Eaton’s documentation and UL/Canada certification reports. The product also lists NEC/CEC compliance and hazardous-location ratings. For installation guidance, consult the Eaton Specification Sheet for LTB150DC and the Crouse-Hinds catalog pages, which provide dimensional data, torque values, and compatibility notes.
The LTB150DC provides a durable, corrosion-resistant zinc die-cast body with insulation that reduces moisture ingress and electrical shorts. Its robust construction lowers field rework, accelerates installation, and helps ensure ongoing compliance with NEC/CEC in hazardous locations. Over time, this can translate to shorter downtime, fewer component replacements, and a lower total cost of ownership in harsh industrial environments.
