METHYL ETHER Chemical compatibility with O-rings, rubbers, & plastics

Methyl ether, more commonly known as dimethyl ether or DME, is a colorless, highly flammable gas with the chemical formula C2H6O used in aerosol propellants, refrigerants, and alternative fuel systems similar to liquefied petroleum gas. It is also utilized as a solvent and chemical intermediate in pharmaceutical and agrochemical manufacturing. In equipment handling dimethyl ether, O-rings, rubber seals, gaskets, and plastic components should be evaluated for chemical compatibility and pressure performance. Proper storage, ventilation, leak detection, and protective handling procedures are essential to minimize flammability risks and maintain safe operation.
