Introduction

Metal bonded rubber seals are high-precision composite sealing components that combine the strength of metal with the flexibility of rubber. They are engineered to provide exceptional durability, dimensional stability, and leak-proof performance under high pressure, vibration, and temperature fluctuations. The rubber is vulcanized or chemically bonded to a metal insert, ensuring excellent adhesion and long service life even in harsh operating environments.

Applications

Metal bonded rubber seals are widely used in automotive braking systems, engine mounts, shock absorbers, compressors, pumps, valves, and hydraulic equipment. They also play critical roles in oil & gas pipelines, HVAC systems, electronic housings, and industrial machinery, providing secure sealing and vibration damping between rigid metal interfaces. In semiconductor and precision instruments, they ensure contamination-free and high-purity sealing performance.
