Eaton Crouse-Hinds 3/4" Rigid/IMC Sealing Locknut, Steel Construction

Professional-Grade Conduit Sealing Solution for Secure Electrical Connections

The Eaton Crouse-Hinds Series SL Sealing Locknut is a professional-grade steel fitting engineered for secure conduit termination in rigid and IMC electrical systems. This 3/4" sealing locknut delivers superior thread engagement and weatherproof sealing for commercial and industrial electrical installations where reliable conduit connections are critical.

Key Features & Benefits

Superior Sealing Performance

• Integrated Sealing Design - Built-in sealing mechanism prevents moisture and contaminant infiltration at conduit terminations
• Weather-Resistant Construction - Steel construction with protective finish ensures long-term performance in outdoor applications
• NEMA 3 Rating - Provides reliable protection against falling dirt, rain, sleet, and snow
• Positive Thread Engagement - Precision threading ensures secure mechanical connection to enclosures and fittings

Professional Installation Advantages

• Standard Tool Compatibility - Works with standard locknut wrenches and spanner tools for efficient installation
• Dual Conduit Compatibility - Designed for both rigid steel and intermediate metal conduit (IMC) systems
• Code Compliant Design - Meets NEC/CEC requirements for conduit sealing and grounding continuity
• Compact Profile - Low-profile design minimizes space requirements in crowded electrical enclosures

Technical Specifications

This Series SL sealing locknut features 3/4" trade size threading compatible with rigid steel conduit and IMC systems. The steel construction provides excellent mechanical strength and corrosion resistance, while the integrated sealing mechanism achieves NEMA 3 environmental protection. Product dimensions measure 1.76" length, 1.12" width, and 0.7" height, with a lightweight 0.02 lb design that won't add unnecessary bulk to installations. The locknut meets NEC/CEC compliance standards for ordinary/non-hazardous locations.

Installation Process

1. Thread conduit through enclosure knockout or hub opening to desired position
2. Apply appropriate thread sealant or compound to conduit threads if required by application
3. Thread sealing locknut onto conduit end, ensuring proper sealing element alignment
4. Tighten locknut using spanner wrench or locknut tool to manufacturer's torque specifications
5. Verify sealing element is properly compressed and positioned for environmental protection
6. Test connection for mechanical security and proper grounding continuity

Applications

Perfect for:

• Outdoor Electrical Enclosures - Motor control centers, disconnect switches, and distribution panels exposed to weather
• Commercial Building Systems - Office buildings, retail facilities, and institutional electrical installations
• Industrial Process Equipment - Manufacturing machinery, processing equipment, and control panel connections
• Municipal Infrastructure - Street lighting, traffic control systems, and public facility electrical systems
• Agricultural Applications - Barn electrical systems, irrigation controls, and outdoor equipment connections
• HVAC Equipment Connections - Rooftop units, outdoor condensers, and mechanical equipment electrical feeds
• Parking Structure Lighting - Garage lighting systems and security equipment installations
• Telecommunications Equipment - Cell tower equipment, outdoor communication cabinets, and antenna systems

Sealing Locknut System Benefits

Sealing locknuts provide superior environmental protection compared to standard locknuts by incorporating weatherproof sealing directly into the connection point. This integrated approach eliminates the need for separate sealing compounds or gaskets while ensuring reliable long-term performance. The combination of mechanical securing and environmental sealing in a single component reduces installation time and potential failure points in outdoor electrical systems.

Why Choose Steel Construction?

Steel sealing locknuts offer exceptional mechanical strength and durability for demanding electrical applications. The steel construction provides superior thread engagement strength compared to lighter materials, ensuring secure connections that won't loosen under vibration or thermal cycling. Combined with Eaton Crouse-Hinds' century of electrical innovation, this sealing locknut delivers the professional-grade performance that electrical contractors trust for critical installations requiring both mechanical security and environmental protection.
