Technical Specifications

Nominal Size: 1-1/2 inch, Outside Diameter: 2.29 inches, Material: Gray PVC, Length: 9.71 inches, UL Listed: E23018, Special Feature: Molded-in mid-point indicator on piston, Selling Unit: Each, Application: Temperature compensation in exposed conduit runs

Installation Process

1. Measure conduit run length and calculate expected thermal expansion based on temperature range and conduit material
2. Position expansion fitting at appropriate location in conduit run, typically at building expansion joints or long straight runs
3. Install conduit sections into both ends of expansion fitting, ensuring proper engagement with internal components
4. Align mid-point indicator on piston to center position for optimal expansion and contraction range
5. Secure conduit system supports on both sides of expansion fitting to allow proper movement
6. Test fitting movement by applying gentle pressure to verify smooth piston operation and proper alignment

Professional Applications

Ideal for:

• Exposed Conduit Systems - Outdoor electrical installations subject to temperature variations and thermal expansion
• Building Expansion Joints - Electrical conduit systems crossing structural expansion joints in commercial buildings
• Long Conduit Runs - Extended straight conduit runs where thermal movement could stress connections
• Industrial Electrical - Manufacturing facilities with temperature-variable environments requiring flexible conduit systems
• Commercial Rooftop - HVAC and electrical equipment connections on rooftops with extreme temperature swings
• Bridge and Infrastructure - Electrical systems on bridges, overpasses, and infrastructure subject to thermal movement
• Solar Installation Systems - Conduit runs in solar arrays where temperature changes cause significant expansion
• Parking Structure Electrical - Conduit systems in parking garages and structures with temperature exposure
