The CSM Urethane Piston Seal is a two-piece piston seal assembly molded from 93A polyurethane with a 70A energizer. It fits the same groove dimensions as standard O-rings or T-seals and can accommodate one or two back-up rings for wider grooves. Engineered for extrusion resistance, the CSM seal also resists rolling and twisting. Its simple two-step snap-in installation requires no resizing before insertion into the bore, providing a straightforward installation process. The -WB suffix designates the wide-base version.
