Spruce Flexible Coupling – 4" × 4" White
Flexible PVC coupling for connecting 4" to 4" Schedule 40 PVC pipe in radon mitigation systems.
The Spruce 4" × 4" white flexible coupling provides a secure, airtight connection between two sections of 4" Schedule 40 PVC pipe. Built with high-performance flexible PVC and a stainless steel clamp, this coupling absorbs vibration, accommodates minor misalignment, and creates a reliable seal — making it a go-to component for professional radon mitigators and DIY installers alike.
Application
Used to join 4" PVC pipe sections in sub-slab depressurization systems, crawl space ventilation, and soil-gas exhaust piping. Commonly installed between the radon fan and vent stack, or wherever a flexible joint is needed to reduce vibration transfer and simplify pipe alignment.

- Stainless steel clamp included for a secure, airtight seal
