Which O-ring material is best for Ethyl T0butyl Ether?

Materials rated Excellent or Good for Ethyl T0butyl Ether include Fluorocarbon (Viton), Perfluoroelastomer, Aflas (TFE/P). Confirm the final choice against your operating temperature and concentration.

Are these Ethyl T0butyl Ether compatibility ratings guaranteed?

No. Ratings are guideline values at ambient temperature (~20°C) and are not a warranty. Compatibility with Ethyl T0butyl Ether varies with temperature, concentration, pressure and exposure time — always validate for your application.

Choosing a seal material for Ethyl T0butyl Ether

The table above rates every common O-ring elastomer for service in Ethyl T0butyl Ether on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.

For Ethyl T0butyl Ether, the strongest candidates are Fluorocarbon (Viton), Perfluoroelastomer, Aflas (TFE/P). These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
