Eaton LT40090DC Liquidtight Connector - Hazardous Locations
Part Number: LT40090DC
Quick Summary
Eaton LT40090DC Liquidtight connector provides secure FMC conduit joins for hazardous locations. In hazardous environments, space constraints and strict certifications often derail straightforward installations. NEC/CEC compliance for Hazardous and Classified Locations, plus Class I, Division 2 ratings, helps you meet code and reduce risk. The zinc die cast housing provides rugged durability in demanding factories, while its non-insulated design speeds installation and reduces component wear. With a 4 inch trade size and 90° geometry, it fits tight routing paths and streamlines panel or tray layouts. Overall, this solution reduces field rework, lowers total cost of ownership, and speeds uptime in critical process environments.

FAQs
LT40090DC is a 4 inch trade size liquidtight connector for FMC conduit, designed to attach to standard FMC fittings and backs. It supports common 4 inch FMC sizing used in medium diameter flexible conduits, simplifying parts planning and stocking. Follow Eaton’s installation guide for gland seals and gaskets to ensure a moisture-tight seal. This compatibility reduces adapter counts and speeds panel terminations.
LT40090DC carries NEC/CEC compliance for Hazardous/Classified Locations, including Class I Division 2 ratings, and supports area classification requirements. The UL and Eaton documentation confirm suitability for hazardous environments, helping you meet regulatory obligations, reduce risk, and simplify audits. In Canada or the US, these standards align with project specifications and contractor expectations for safe, code-compliant installations.
LT40090DC is well suited for chemical plants, refineries, oil and gas facilities, and other operations with hazardous classifications where durable, compliant fittings are essential. The 90° angle and 4 inch trade size support compact routing near equipment and panels, while the zinc die cast body resists harsh chemicals and thermal cycling. This makes it a reliable choice for retrofit and new builds.
Yes. LT40090DC is designed for Class I Division 2 environments and related hazardous classifications, offering NEC/CEC-compliant sealing and a robust zinc die cast housing. The 90° configuration supports tight installations, while the non-insulated construction simplifies access for inspection and testing. Ensure proper grounding and use Eaton’s recommended gaskets and seals per the product sheet.
Using LT40090DC can reduce installation time and maintenance costs by reducing required adapters, enabling faster terminations, and decreasing rework in hazardous zones. The rugged zinc housing resists corrosion and the 90° fit minimizes required routing space, improving panel density. Over the project life, this translates to lower downtime and a faster return on investment.
