SKYDROL 500 is a phosphate ester hydraulic fluid commonly used in aviation, aerospace, and industrial applications. It is known for its fire-resistant properties and its ability to provide lubrication and corrosion protection.
When exposed to SKYDROL 500, rubber materials can become brittle and lose their physical strength due to the fluid's hygroscopic nature. The fluid can also cause swelling and softening of the rubber material, leading to an increase in compression set and loss of elasticity. In addition, SKYDROL 500 can cause rubber materials to become more prone to cracking and breakage.
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.
