Hydrogen fluoride anhydrous (also known as anhydrous hydrofluoric acid or AHF) is an extremely corrosive and toxic inorganic compound that is used in a variety of industries, including the production of fertilizers, petroleum refining, electroplating, and glass etching.
Common types of failures when rubber is exposed to hydrogen fluoride anhydrous include discoloration, swelling, cracking, and embrittlement due to the corrosive nature of the acid. Additionally, rubber seals exposed to hydrogen fluoride anhydrous may become brittle and prone to cracking or tearing over time, as the acid slowly breaks down the rubber material. Additionally, exposure to hydrogen fluoride anhydrous may cause the rubber seal to swell or become distorted due to its acidic properties.
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.
