Eaton LT3890NM Non-metallic liquidtight connector - Class I/II
Part Number: LT3890NM
Quick Summary
The Eaton LT3890NM non-metallic liquidtight connector provides secure FMC terminations in hazardous-location installations. Installers often struggle to achieve reliable seals and code-compliant wiring without sacrificing ease of installation. This NEC/CEC-compliant fitting is rated for Hazardous/Classified Locations, including Class I Division 2 and Class II Division 1, helping you meet strict safety requirements. In practice, it supports safer assemblies, reduces downtime, and pairs with gray nylon, 3/8-inch FMC fittings for durable, scalable installations. The 90° angle design simplifies routing in tight spaces while maintaining a robust seal.

FAQs
Power must be off and de-energized before work begins. Verify the 3/8" trade size compatibility, insert the FMC into the nylon body, and secure with approved seals or gaskets. Tighten to the manufacturer’s specified torque to ensure a watertight, code-compliant seal. Confirm the assembly remains within Class I Division 2 or Class II Division 1/2 ratings after installation. Consider routing paths that minimize bending stress and provide proper strain relief to extend service life.
LT3890NM is designed to meet NEC/CEC requirements and carries hazardous-location ratings appropriate for Class I Division 2 and related classifications. The nylon body and 90° FMC design enable reliable seals in restricted spaces, reducing ignition risks, moisture ingress, and maintenance cycles in hazardous environments such as chemical processing and oil/gas facilities.
Yes. LT3890NM is specified for FMC conduit and uses a 3/8" trade size to align with common FMC cables. Its gray nylon construction supports straightforward integration with existing non-metallic fittings, simplifying inventory management and project wiring while preserving safety and performance in harsh settings.
LT3890NM aligns with NEC/CEC standards for hazardous locations and has UL certification references for non-metallic liquidtight fittings. You can access the official Eaton specification sheet LT3890NM and UL certification pages for project approvals, compliance audits, and procurement documentation.
Using LT3890NM reduces downtime through faster, reliable terminations and minimizes rework due to compliance issues. The durable nylon body resists moisture and chemicals, extending service life in harsh environments. Combined with NEC/CEC compliance, this can lower maintenance costs and improve system availability in hazardous locations.
