Thank you for choosing SPARKLING MACHINERY.
The 25A / 25AS rubber coupling is manufactured using oil-resistant natural and synthetic elastomer blends integrated with reinforced steel bolt bushings. Engineered to operate under continuous high-torque cycles and engine bay heat, it acts as a mechanical shock absorber between the flywheel and hydraulic pump. Replacing a hardened, sheared, or cracked coupling eliminates flywheel-to-pump vibration, prevents splined shaft wear, and restores smooth hydraulic power output.
