HEXALDEHYDE Resistant O-Rings and Seals
Hexaldehyde, also known as formalin, is a colorless, flammable liquid with a pungent odor. It is commonly used as a disinfectant, preservative, and fumigant, as well as in a variety of industrial processes.
When rubber is exposed to hexaldehyde, the material can become brittle and break down due to oxidation. The gas can also cause swelling, leading to distortion and reduced performance. The rubber may become sticky, leading to further issues with sealing capabilities, and in extreme cases, the material may experience irreversible damage.
EPDM (EP, EPR, Ethylene-Propylene Rubber)
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.
