Brake Fluid Rubber Compatibility

First of all it s.

Brake fluid rubber compatibility.

The additive package controls the ph of the fluid and the viscosity. Or second you can select a specific chemical to view all its compatible o ring materials. Fluid boiling point and other physical characteristics. All polyethylene glycol based fluids will not harm healthy rubber parts.

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. All dot 3 4 and 5 1 brake fluids are compatible with each other and with all systems. Additionally some technical comments will be made about the new brake fluid formulations appearing on the scene. First you can select a specific o ring material to view its compatible chemicals.

This page contains a guide to selecting o ring materials based on chemical compatibility requirements. Fluid compatibility with the brake system rubber plastic and metal components. If the brake fluid becomes unable to control the ph or other corrosive elements the rubber and metal parts will deteriorate over time. Welcome to our rubber chemical resistance chart.

Even an older rubber part with a high concentration of natural rubber will not be damaged by new dot rated brake fluids. Also the additive packages will not damage or distort any rubber parts. If you have an older vehicle and are worried about boiling the fluid use dot 4 or 5 1 brake fluid. Brake system contamination and sludging.

The chemical compatibility data can be presented in one of two ways. Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure.
