The expanded rubber material boasts excellent water resistance, aging resistance, and compatibility with UPVC pipes, preventing corrosion and leakage caused by long-term water immersion. Its R-shaped design enhances contact area with pipe interfaces, effectively absorbing slight dimensional deviations and vibration, while the high elasticity ensures easy installation and long service life. Compliant with drinking water safety standards, it’s ideal for cold/hot water UPVC pipe connections, including water supply pipelines, faucets, and pipe fittings.
