MATERIAL SELECTION FOR MECHANICAL SEALS
including metals, elastomers, and ceramics. Each of these materials plays an important role in the operation of the seal. Seal manufacturers have narrowed the list of available materials through years of successful field experience. Still, the selection of the correct materials remains a critical step in the successful applica-tion of a ...
