The Crest MSC mechanical seal is designed for use in the harshest of corrosive environments such as acids, organic compounds and salts. The bellows are machined from solid PTFE allowing for longitudinal movement with external multi-springs to ensure even pressure on the seal face.

For liquids that contain abrasive solids, the SiC face and seat is an ideal combination.
