Technical Specifications

Size: 1-1/4 inch nominal diameter for standard PVC conduit compatibility. Material: Non-metallic PVC construction with molded piston assembly. UL Rating: Listed under UL E23018 for electrical conduit applications. Package: 5-piece contractor pack for professional installation efficiency. Special Feature: Exclusive molded-in mid-point indicator on piston for precise positioning reference.

Installation Process

1. Measure conduit run length and calculate expected thermal expansion based on temperature range and conduit material specifications
2. Position expansion fitting at calculated mid-point of long conduit runs, typically every 100-200 feet depending on local codes
3. Align molded mid-point indicator on piston to center position before making final conduit connections
4. Secure conduit connections using appropriate PVC cement or mechanical couplings per manufacturer specifications
5. Verify proper piston movement range by checking indicator positioning during temperature cycling
6. Document installation locations and settings for future maintenance and inspection requirements

Professional Applications

Ideal for:

• Exposed Conduit Runs - Long outdoor conduit installations subject to significant temperature variations and thermal cycling
• Commercial Electrical Systems - Large building electrical distribution where conduit expansion must be controlled
• Industrial Installations - Manufacturing facilities with temperature-sensitive electrical conduit routing requirements
• Rooftop Electrical Systems - Solar panel wiring and HVAC electrical connections exposed to extreme temperature changes
• Parking Structure Wiring - Exposed conduit systems in parking garages requiring thermal expansion accommodation
• Bridge and Infrastructure - Electrical conduit systems on bridges, overpasses, and similar structures with thermal movement
• Long Underground Runs - Buried conduit systems where soil temperature variations cause expansion concerns
• Process Piping Areas - Electrical conduit near hot process equipment requiring thermal expansion control
