Nitrile rubber also known as acrylonitrile butadiene nbr and buna n.
Brake fluid resistant rubber.
I was wondering if something along the lines of a polyurethene or pvc type clear hose or a sillicone rubber based hose would be ok to run with brake fluid or would the type of material the hose.
Welcome to our rubber chemical resistance chart here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals.
Heat cold and.
Selection of the correct elastomeric rubber material for your application be it fluid or environmental sealing vibration isolation or dampening impact bumpers hoses and fluid movement and various other requires the review of numerous factors such as.
The acrylonitrile content varies between 18 and 50 and influences the physical properties of the finished product.
A higher nitrile content enhances resistance to fuel and oil but elasticity and resistance to compression set is adversely affected.
Of these three rubber types epdm is the only choice for seals in braking systems using a glycol based or silicone based dot approved or pure racing brake fluid.
If you buy your brake fluid from pegasus auto racing supplies use epdm seals in that system don t panic most companies that make master cylinder and caliper seals only offer them.

Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure.
When water is absorbed the boiling point is sharply lowered.

When brake fluid is mixed with water the boiling point of the mixture is less than that of the dry brake fluid.
Glycol based brake fluids in particular are hygroscopic moisture absorbing some more so than others.

Dynamic or static application system pressure chemical compatibility.
This occurs because water boils at only 212 f.
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.
