Technical Specifications

This sealing locknut accommodates 2-1/2" trade size rigid and IMC conduit with standard NPT threading. The malleable iron construction provides superior mechanical properties compared to steel alternatives, with enhanced impact resistance and dimensional stability. Product dimensions are 3.96" length x 2.48" width x 1.35" height, weighing 0.28 pounds for optimal strength-to-weight ratio. Manufactured to NEC/CEC compliance standards for ordinary/non-hazardous locations with NEMA 3 environmental protection rating.

Installation Process

1. Verify conduit end is properly reamed and deburred to prevent damage to sealing surfaces
2. Apply appropriate thread sealant or sealing compound to conduit threads as required by application
3. Thread sealing locknut onto conduit end, ensuring proper thread engagement and alignment
4. Position conduit assembly through enclosure knockout or entry point
5. Tighten locknut against enclosure wall using appropriate wrench, ensuring gasket compression if applicable
6. Verify proper sealing position and torque specification compliance per manufacturer guidelines

Applications

Perfect for:

• Outdoor Electrical Installations - Weather-exposed conduit terminations requiring moisture protection
• Industrial Facilities - Manufacturing environments with washdown requirements or high humidity
• Commercial Buildings - Office complexes, retail centers, and institutional facilities
• Municipal Infrastructure - Schools, government buildings, and public utility installations
• Agricultural Applications - Barn electrical systems, irrigation controls, and livestock facility wiring
• Equipment Connections - Motor control centers, switchgear, and distribution panel terminations
• Rooftop Installations - HVAC equipment connections and rooftop electrical distribution
• Parking Structure Wiring - Covered parking and garage electrical systems requiring environmental protection

Sealing Locknut System Benefits

Sealing locknuts provide critical environmental protection that standard locknuts cannot match, making them essential for installations where moisture intrusion could compromise electrical safety or equipment reliability. The integrated sealing design eliminates the need for separate weatherproofing measures while maintaining the mechanical securing function of traditional locknuts. This dual-purpose functionality reduces installation complexity and long-term maintenance requirements compared to multi-component sealing solutions.

Why Choose Malleable Iron Construction?

Malleable iron offers superior mechanical properties compared to standard steel fittings, with enhanced impact resistance and dimensional stability under thermal cycling. This material choice ensures reliable performance in demanding electrical environments where fitting failure could result in costly downtime or safety hazards. The precision casting process used in malleable iron production delivers consistent thread quality and sealing surface finish, critical factors for long-term environmental protection in professional electrical installations.
