Technical Specifications

The STL thread lubricant features a specialized formulation designed specifically for electrical conduit systems. The 8 oz can provides sufficient coverage for multiple installations while maintaining portability. Operating temperature range spans from -20°F to +300°F, making it suitable for both outdoor winter installations and high-temperature industrial environments. The compound meets NEC/CEC standards for electrical installations and is compatible with all standard conduit materials including steel, aluminum, and PVC-coated conduit.

Installation Process

1. Clean threads on both conduit and fitting to remove dirt, debris, or old compound
2. Apply thin, even coat of STL lubricant to male threads using brush or applicator
3. Ensure complete thread coverage without over-application
4. Hand-start threaded connection to prevent cross-threading
5. Tighten to manufacturer's specified torque using appropriate wrenches
6. Wipe excess compound from joint exterior for clean appearance

Applications

Perfect for:

• Rigid Conduit Systems - Steel and aluminum rigid conduit connections
• IMC Installations - Intermediate metal conduit threading applications
• Outdoor Electrical - Weather-exposed conduit systems requiring corrosion protection
• Industrial Facilities - High-temperature environments and heavy-duty installations
• Commercial Buildings - Office complexes, retail centers, and institutional facilities
• Municipal Infrastructure - Schools, hospitals, and government building electrical systems
• Equipment Connections - Motor control centers, switchgear, and panel connections
• Maintenance Operations - Retrofit work and system modifications

Thread Compound System Benefits

Professional thread lubricants like STL provide critical advantages over dry assembly or improvised lubricants. The specialized formulation creates a protective barrier that prevents galvanic corrosion between dissimilar metals while ensuring proper electrical continuity. This is especially important in conduit systems where grounding continuity must be maintained throughout the installation. The lubricant also compensates for minor thread imperfections and manufacturing tolerances, creating more reliable, leak-resistant joints.
