Eaton LTB12590SS Liquidtight Connector - Hazardous Locations
Part Number: LTB12590SS
Quick Summary
LTB12590SS is a stainless steel liquidtight connector for hazardous locations in industrial control systems. When installations demand rugged seals and corrosion resistance, ordinary fittings can fail, causing moisture ingress and downtime. This connector carries NEC/CEC compliance and is rated for Class I, Division 2; Class II/III locations, supporting safe operation in demanding environments. In addition to safety, its insulated stainless steel body enhances durability in FMC conduit systems, boosting install efficiency and lifecycle value. Operators benefit from reduced spares and faster panel wiring thanks to its compact form and reliable sealing. Engineers appreciate the documented NEC/CEC conformity and the robust metal-to-metal connection that remains secure under vibration.

FAQs
Begin with de-energizing the system and selecting the 1-1/4" FMC conduit compatibility. Align the connector with the conduit, secure the seal, and tighten to the manufacturer’s torque specification using standard hand tools. Verify ground continuity and perform a simple continuity check after installation to ensure a proper seal in Class I Division 2 environments.
The LTB12590SS adheres to NEC/CEC standards and is rated for Hazardous/Classified Locations, including Class I Division 2 and Class II/III locations. This makes it appropriate for chemical plants, oil & gas facilities, and other demanding industrial settings where rigorous protection of electrical joints is required.
Yes, the LTB12590SS is a 1-1/4" trade size FMC conduit connector. Its external dimensions are 3.15 in length and height, 2.17 in width, with an approximate weight of 0.96 lb, making it suitable for compact panel designs and tight routing.
Stainless steel provides superior corrosion resistance, while insulation maintains a reliable seal and electrical isolation. Together they reduce maintenance cycles, lower leak risks, and improve lifecycle cost in harsh environments such as chemical processing or outdoor industrial installations.
Regularly inspect the connector for signs of seal wear, corrosion, or loosening after commissioning and periodic maintenance. Verify torque integrity and assess any impact of vibration. Document compliance with NEC/CEC during audits and replace seals or hardware per the manufacturer’s service interval to maintain hazardous location integrity.
