Project details

EPDM O-ring seals for brake fluid are usually used as seals in brake systems to prevent leakage of brake fluid.

Brake fluid is the medium used to transmit braking pressure in the automotive braking system, and it is crucial for the normal operation of the braking system. If brake fluid leaks, it may lead to a decrease or loss of braking performance, thereby increasing the risk of accidents for the vehicle. Therefore, O-ring seals for brake fluid play a very important role in the braking system.

EPDM (ethylene propylene diene) is a polymer material with excellent resistance to high temperature, oil, ozone, and aging. Therefore, EPDM O-ring seals for brake fluid have excellent high-temperature resistance and sealing performance, and can work normally in the high-temperature and high-pressure environment of the braking system.

The manufacturing process of EPDM O-ring seals for brake fluid typically includes the following steps:

Ingredients: Mix EPDM and other additives in a certain proportion to make a basic formula.

Refining: Add the basic formula to the mixer, heat, soften, and mix evenly to make the rubber material.

Forming: Place the rubber material into the mold, heat and pressure it to create an O-ring shape.

Vulcanization: Place the formed O-ring in a vulcanization machine and perform vulcanization treatment under high temperature and pressure to crosslink and solidify the rubber material, making an EPDM O-ring with a certain hardness and elasticity.

Inspection: Perform dimensional inspection, pressure test, and sealing performance test on the O-ring made, and ensure that it meets the standards before leaving the factory for use.

When using EPDM O-ring seals for brake fluid in the braking system, they are generally installed at the gap between the brake piston and the brake hydraulic cylinder to prevent internal and external leakage of the brake fluid. Due to the harsh working environment of the braking system, the O-ring is required to have good high-temperature resistance and sealing performance to ensure the normal operation of the braking system.
