DK102R: Piston U-Cup Seal w. Rectangular Back-up Ring

SCS, INC. DK102R:   Single acting asymmetrical U-cup piston seal with an integrated rectangular back-up ring. An excellent choice for medium to heavy duty hydraulic and pneumatic applications.

The snap in design allows for easy installation and is an outstanding choice for large piston diameters. This piston seal avoids extensive drag pressure in a back to back arrangement with guide rings between or for double acting pistons or to separating different sealing medias. Extremely adaptive possibilities for diverse temperatures and media with a wide selection of seal materials. Available in standard, metric and custom sizes from 0-200″ in diameter.
