Technical Specifications

This 4-inch trade size gasket features PVC construction with an integrated steel reinforcement ring for enhanced durability. The gasket measures 5.19 inches in length and width with a 0.19-inch profile height, weighing just 0.1 pounds for easy handling. The self-retaining design is specifically engineered for rigid steel and IMC conduit systems, providing NEC/CEC compliant sealing performance in ordinary/non-hazardous locations. The precision-molded profile ensures consistent compression characteristics and optimal sealing performance across a wide range of installation conditions.

Installation Process

1. Verify conduit end is clean, smooth, and free from burrs or debris that could compromise seal integrity
2. Inspect gasket for any damage or deformation before installation
3. Position the self-retaining gasket in the conduit fitting groove, ensuring the steel ring faces the compression surface
4. Verify gasket is seated evenly around the entire circumference with no twisting or displacement
5. Assemble conduit connection, applying steady pressure to achieve proper compression without over-tightening
6. Confirm gasket remains properly positioned and provides uniform compression around the joint

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities requiring weather-sealed conduit connections
• Industrial Facilities - Manufacturing plants, processing facilities, and warehouses with exposure to moisture and contaminants
• Outdoor Installations - Exterior conduit runs, rooftop equipment connections, and underground-to-above-ground transitions
• Municipal Infrastructure - Government buildings, schools, and public facilities requiring long-term reliability
• Equipment Connections - Motor control centers, switchgear, and electrical panels in demanding environments
• Wet Location Applications - Areas subject to moisture, washing, or high humidity conditions
• Chemical Processing - Facilities where chemical resistance of PVC material provides superior performance
• Food Processing - Clean environments requiring washdown capability and chemical resistance

Self-Retaining Gasket System Benefits

Self-retaining gaskets represent a significant advancement over traditional loose gaskets by eliminating common installation problems such as gasket displacement, misalignment, and loss during assembly. The integrated retention feature ensures the gasket stays exactly where needed throughout the installation process, resulting in more consistent sealing performance and reduced callback issues. This design is particularly valuable in overhead installations or confined spaces where gasket positioning can be challenging.

Why Choose PVC with Steel Ring Construction?

The combination of PVC elastomer with steel ring reinforcement provides the ideal balance of sealing performance and structural integrity. PVC offers excellent chemical resistance, UV stability, and long-term flexibility, while the steel ring prevents gasket deformation under compression and maintains consistent sealing force. This hybrid construction ensures reliable performance across temperature variations and provides superior resistance to the environmental stresses common in electrical installations, making it the preferred choice for professional contractors who demand long-term reliability.
