PVC-U Water Supply Pipe Seal – R-Shaped Expansion Rubber Ring
This R-shaped expansion rubber seal ring is specially designed for PVC-U water supply pipe fittings, complying with water supply grade safety standards. Made of premium food-grade NBR/EPDM rubber, it’s non-toxic, odorless, and safe for drinking water contact, resisting corrosion from tap water, weak acids, and alkalis.
The innovative R-shaped expansion structure automatically fits pipe interface gaps when under water pressure (≤1.6MPa), ensuring tight leak-proof sealing. It adapts to -20℃~80℃ working temperatures, with excellent elasticity and aging resistance for long-term use in residential, commercial, and municipal PVC-U water supply systems. Easy to install without additional tools, it’s a reliable sealing solution for PVC-U pipe connections and fittings.
