Technical Specifications

This sealing locknut features 1/2 inch trade size threading compatible with rigid and IMC conduit systems. The steel construction provides exceptional durability with dimensions of 1.12 inches length, 0.86 inches width, and 0.72 inches height. The unit weighs 0.01 pounds and meets NEC/CEC compliance standards for ordinary/non-hazardous locations. NEMA 3 rating capability when properly installed with appropriate sealing components.

Installation Process

1. Thread conduit fitting through enclosure wall opening
2. Position sealing washer or gasket against enclosure interior surface
3. Thread sealing locknut onto conduit fitting from inside enclosure
4. Tighten locknut using appropriate wrench to compress sealing element
5. Verify proper sealing compression without over-tightening
6. Check that conduit fitting remains properly aligned after tightening

Applications

Perfect for:

• Outdoor Electrical Enclosures - Motor control centers, disconnect switches, and junction boxes
• Wet Location Installations - Car washes, food processing facilities, and exterior mounting applications
• Industrial Control Panels - Manufacturing equipment, process control systems, and automation enclosures
• Commercial Building Systems - HVAC controls, lighting panels, and distribution equipment
• Municipal Infrastructure - Traffic control systems, street lighting, and public facility electrical systems
• Agricultural Applications - Irrigation controls, barn electrical systems, and outdoor equipment connections
• Marine and Coastal Installations - Docks, piers, and waterfront electrical systems requiring moisture protection
• Chemical Processing Facilities - Areas requiring enhanced sealing against moisture and environmental contaminants

Sealing Locknut System Benefits

Sealing locknuts provide superior protection compared to standard locknuts by creating a weatherproof barrier at the conduit entry point. This prevents moisture infiltration that can cause equipment failure, corrosion, and safety hazards. The integrated sealing design eliminates the need for additional sealing compounds while providing reliable, long-term protection that meets NEMA environmental ratings.

Why Choose Steel Construction?

Steel sealing locknuts offer exceptional mechanical strength and durability for demanding applications. The material provides superior thread engagement and resistance to loosening under vibration or thermal cycling. Steel construction ensures reliable performance in high-stress installations while maintaining the precision threading required for proper sealing compression. This makes steel sealing locknuts the preferred choice for industrial and commercial applications where long-term reliability is essential.
