METHYL MERCAPTAN Resistant O-Rings and Seals
Methyl Mercaptan, also known as Methanethiol or Methyl Sulphide, is an organic compound with a strong odour that is used in the production of pesticides, flavO-Rings, and fragrances.
When rubber is exposed to Methyl Mercaptan, it can cause oxidation of the rubber, leading to cracking and brittleness. The chemical can also cause swelling and discoloration of the rubber due to its acidic nature. Additionally, prolonged exposure can cause the rubber to become brittle, leading to potential failure of the rubber seal.
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.
