Product details

The XJ-6 expansion joint is designed for 6" vertical DWV piping systems, providing a reliable solution for managing thermal expansion and contraction in larger diameter applications. Its one-piece, no-moving-parts construction eliminates mechanical failure points while delivering consistent, maintenance-free performance. Ideal for commercial and multi-story buildings, it accommodates system movement while maintaining proper alignment and reducing stress on piping caused by temperature fluctuations.

Maintenance-free performance. No moving components to wear out or fail, delivering long-term reliability without the need for ongoing maintenance.
