Eaton LTK7545 Liquidtight Connector - Hazardous Locations
Part Number: LTK7545
Quick Summary
LTK7545 liquidtight connector from Eaton Crouse-Hinds is a rugged FMC fitting that secures conduit in hazardous locations. Installers often face tight spaces and strict safety standards, making a compact, compliant connector essential for reliable wiring. It carries NEC/CEC compliance with area classification and hazardous-location ratings such as Class I, Division 2, and Class II/III configurations. The low-profile, 3/4 inch design reduces installation time and simplifies panel layouts, while non-insulated malleable iron delivers durability in harsh environments. For OEMs and maintenance teams, this connector enables predictable performance, long service life, and easier regulatory approvals.

Eaton Specification Sheet - LTK7545
The 45° angle FMC liquidtight design improves routing in confined spaces, reducing bend radius and facilitating quick field terminations. This directly translates to faster panel installs, less labor cost, and lower risk of conduit damage in the field. In hazardous locations, the low-profile form factor minimizes clearance issues while preserving a robust seal, enabling safer, more compact enclosures. Constructed from malleable iron and finished without insulation, the LTK7545 combines mechanical strength with thermal resilience, delivering durable service in oil, gas, and chemical plant environments. The 3/4" trade size aligns with common industrial conduits, simplifying spares management and procurement. NEC/CEC compliance and explicit Class I Division 2 ratings reduce regulatory hurdles, speeding project sign-offs and reducing rework. Its compact dimensions and modest weight (0.3 lb) support easy handling during installation in cramped panels and restricted spaces. Long-term reliability minimizes maintenance cycles and supports predictable lifecycle costs for hazardous-location wiring.

FAQs
LTK7545 is designed for FMC conduit with a 3/4" trade size. It provides a secure, tight seal for flexible metal conduit systems in hazardous areas and pairs with standard FMC fittings and locknut practices to maintain code-compliant terminations in Class I/II environments.
LTK7545 carries NEC/CEC compliance and area classification for hazardous locations, including Class I, Division 2, Class II Division 1 and 2, and Class III. This certified rating supports installation approvals in classified locations and aligns with Canadian certification expectations for safe operation in harsh environments.
Yes. The LTK7545 is specified for hazardous/classified locations with Class I, Division 2 ratings, enabling reliable operation in areas with potentially explosive atmospheres. Ensure proper installation practices and sealing to maintain integrity under safety regimes.
Prioritize correct 3/4" FMC termination hardware and torque per manufacturer guidance. The 45° angle and low-profile design reduce clearance issues, while the malleable iron body provides rugged mechanical protection. Use appropriate gaskets or glands where required and verify clean conduit paths to prevent seal compromise in harsh environments.
The combination of durable malleable iron, non-insulated construction, and a compact, low-profile form factor reduces maintenance needs and rework in hazardous locations. Compliance with NEC/CEC simplifies approvals, shortening project timelines and improving overall ownership cost through fewer field-termination failures and longer service life.
