ISO4925 Rubber Cup Adaptability Measuring Instrument for Brake Fluid

Summary

This Brake Fluid Rubber Cup Adaptability Measuring Instrument is primarily used to assess the compatibility of brake fluid and its raw materials with the rubber cups used in the hydraulic brake systems of motor vehicles.

The principle involves immersing the rubber cup or rubber test piece in the brake fluid, maintaining it at a specified temperature for 70 hours, and then inspecting its appearance, root diameter changes, hardness changes, and volume changes according to the product standard requirements.
