Eaton Specification Sheet - LTBK5045
Feature: The LTBK5045 delivers a 45° FMC liquidtight connector with a low-profile body. Business impact: The angled design reduces bend radius, enabling faster wiring and fewer mounting supports, especially in crowded panels. Application: Ideal for machine controls, panel feeds, and field installations where space is limited and reliable sealing is essential in hazardous environments. Feature: Malleable iron construction with insulated body. Business impact: Provides rugged durability and moisture sealing to protect conductors against vibration, impact, and corrosion in harsh environments, lowering maintenance costs and downtime. Application: Chemical plants, oil and gas facilities, and mining operations where equipment experiences heavy use and temperature swings. Feature: 1/2 inch trade size with compact footprint (2.34 in long, 2.22 in high, 2.22 in wide) and a light 0.21 lb weight. Business impact: Simplifies stocking and field replacement by aligning with common FMC components, accelerating installation and reducing inventory costs. Application: Wiring runs in control panels, compact machinery, and hazardous locations where space is constrained. Feature: NEC/CEC compliance with hazardous-location ratings including Class I Division 2, Class II Division 1 and 2, and Class III. Business impact: Enables safe operation in regulated environments and supports project approvals, reducing compliance risk and rework. Application: Electrical installations in chemical plants, refineries, water treatment, and other facilities requiring certified fittings for hazardous areas. Feature: Compatibility with FMC conduit types and a fixed 45° orientation simplifies field routing. Business impact: Reduces installation errors and rework by providing a consistent, pre-aligned connection. Application: New installations and retrofit projects in industrial plants, where quick, repeatable connections improve overall project timelines and reliability. Feature: High-quality Eaton construction and widely cataloged specs support long service life and straightforward parts replacement. Business impact: Fewer field failures, lower maintenance costs, and predictable budgeting across asset lifecycles. Application: Refurbishment projects and new builds across manufacturing, process industries, and energy sectors where reliability and supplier support matter.

FAQs
LTBK5045 is designed for 1/2 inch FMC conduit and insulated malleable iron construction, delivering a tight seal and robust mechanical connection. It supports Hazardous/Classified Locations per NEC/CEC with Class I Division 2 ratings, making it suitable for chemical plants, refineries, and mining installations. It integrates with standard FMC fittings for straightforward field assembly.
The 45° angle orientation reduces bend radius and clearance requirements, enabling cleaner routing through crowded electrical panels and confined enclosures. This translates to fewer mounting hooks and supports, faster terminations, and less time spent aligning straight fittings in the field, all while preserving a watertight, code-compliant seal.
Yes. The LTBK5045 carries NEC/CEC compliance with hazardous-location ratings, including Class I Division 2, Class II Division 1 and 2, and Class III, along with area classifications for Hazardous/Classified Locations. This alignment supports safe installation in chemical processing, mining, and energy facilities and helps streamline project approvals and regulatory audits.
Key dimensions for LTBK5045 include length 2.34 in, height 2.22 in, width 2.22 in, and weight 0.21 lb. The 1/2 inch trade size aligns with standard FMC conduit, and the UPC is 784564000101. These specs help engineers quickly verify fit and plan mounting clearances during design reviews. The rugged malleable iron body and insulated construction further support long-term reliability.
LTBK5045’s low-profile, 45° orientation reduces enclosure footprint and minimizes hardware while maintaining sealed connections, speeding installations and reducing labor costs. Its NEC/CEC and Class I Division 2 ratings help meet regulatory requirements from the outset, lowering risk of noncompliance fines and maintenance downtime. Quick, reliable field service translates into measurable ROI over asset lifecycles.
