Technical Specifications

This expansion coupling accommodates 1-1/4 inch nominal size rigid conduit with 1.68 inch inside diameter and 2.41 inch outside diameter. Constructed from durable gray PVC material with Schedule 40 rating, featuring 4 inch product length and UL E23018 certification. Expands to maximum 2 inches to accommodate thermal movement while maintaining secure electrical conduit connections.

Installation Process

1. Measure required expansion distance ensuring it does not exceed 2-inch maximum capacity for reliable performance
2. Clean conduit ends thoroughly and inspect for damage that could compromise connection integrity
3. Apply appropriate PVC primer and cement to conduit ends following manufacturer specifications
4. Insert first conduit end fully into coupling ensuring proper seating and alignment
5. Position coupling at desired expansion length within the 2-inch maximum range
6. Connect second conduit end with proper cement application for permanent, leak-proof seal

Professional Applications
