DELCO Brake Fluid is a type of brake fluid used in automotive vehicles and is made from a mixture of glycol ethers, polyglycols, and other additives. It is used as a hydraulic fluid in brake systems, as well as in other automotive applications. Common uses of DELCO Brake Fluid include lubricating the seals and other components of the brakes, transferring heat away from the brakes, and providing a seal between the brake pads and rotor.
When exposed to DELCO Brake Fluid, rubber materials can experience swelling, softening, and chemical attack. Swelling of the rubber material can occur due to the glycol ethers and polyglycols in the brake fluid, resulting in an increase in volume and a decrease in tensile strength. Softening of the rubber material can occur due to the leaching of plasticizers, resulting in a decrease in the rubber's hardness and a decrease in its ability to resist abrasion. Chemical attack of the rubber material can occur due to the presence of dissolved oxygen in the brake fluid, which can cause degradation of the rubber material due to oxidation.
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. Marco Rubber has the world’s largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available. Whether it’s for water systems, braking systems, medical, pharmaceutical, food or dairy use, you can count on Marco Rubber to deliver your o-rings fast and efficiently.
