Brake Fluid Rubber Compatibility

Even an older rubber part with a high concentration of natural rubber will not be damaged by new dot rated brake fluids.

Brake fluid rubber compatibility.

Fluid boiling point and other physical characteristics. Welcome to our rubber chemical resistance chart. Exposing rubber o ring materials to multiple chemicals and compounding application factors like temperature pressure and gland design can result in significantly different. Or second you can select a specific chemical to view all its compatible o ring materials.

First of all it s. If you have an older vehicle and are worried about boiling the fluid use dot 4 or 5 1 brake fluid. All dot 3 4 and 5 1 brake fluids are compatible with each other and with all systems. Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment.

Fluid compatibility with the brake system rubber plastic and metal components. The chemical compatibility data can be presented in one of two ways. All polyethylene glycol based fluids will not harm healthy rubber parts. First you can select a specific o ring material to view its compatible chemicals.

Also the additive packages will not damage or distort any rubber parts. Brake system contamination and sludging. This page contains a guide to selecting o ring materials based on chemical compatibility requirements. Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure.

Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. The additive package controls the ph of the fluid and the viscosity.
