Spruce Flexible Coupling – 4" × 3" White
Flexible PVC reducer coupling for connecting 4" to 3" Schedule 40 PVC pipe in radon mitigation systems.
The Spruce 4" × 3" white flexible coupling provides a secure, airtight transition between 4" and 3" Schedule 40 PVC pipe. Built with high-performance flexible PVC and a stainless steel clamp, this reducer coupling absorbs vibration, accommodates minor misalignment, and creates a reliable seal at pipe-size transitions — essential for professional radon mitigation installations.
Application
Used wherever a radon mitigation system transitions between 3" and 4" PVC pipe — typically at the radon fan inlet or outlet, or when connecting to existing 3" vent piping. Ideal for sub-slab depressurization, crawl space ventilation, and soil-gas exhaust systems.
Features
- High-performance flexible PVC construction
- Stainless steel clamp included for a secure, airtight seal
- White finish blends with Schedule 40 PVC pipe
- Absorbs vibration from inline radon fans
- Accommodates minor pipe misalignment
- 4" to 3" reducer — transitions between standard Schedule 40 PVC sizes
