PVC Reinforced Expansion Joint with Cleanout is engineered for modern piping systems, combining durability and functionality for applications in building drainage, industrial pipelines, and municipal infrastructure. Constructed from high-strength PVC, it offers resistance to corrosion and aging, ensuring long-term performance in challenging environments including moisture and chemical exposure.
The joint features an internally reinforced rib structure that significantly enhances pressure resistance and structural stability, minimizing deformation under dynamic loads or vibration. Its flexible expansion section accommodates thermal expansion, contraction, and minor ground movement, preventing stress-induced cracks and leaks at the connection points.
A dedicated cleanout port is integrated into the side of the joint, allowing easy access for routine maintenance. This feature enables quick removal of debris or sediment without dismantling the entire pipeline, reducing downtime and labor costs—ideal for systems prone to clogging or requiring regular inspection.
Available in multiple configurations, the product includes standard sizes such as D50, D75, and D110, as well as reduced-union variants like D75×50, D110×50, and D110×75, providing versatility for different pipe diameter transitions. This range supports both new installations and retrofit projects with reliable, seamless connections.
Packaging is optimized by size to ensure safe transport and efficient storage. Each box contains 120 units for D50, 36 for D75, 24 for D110, 56 for D75×50, 36 for D110×50, and 30 for D110×75, facilitating bulk handling and on-site logistics.
The compact design ensures a secure fit, with a dual-seal system using rubber gaskets to prevent leakage. Installation is tool-free and straightforward, suitable for both indoor and outdoor use. This joint delivers a reliable, low-maintenance solution that enhances the overall integrity and serviceability of piping systems.
