Rubber UNS Type U Ring

The UNS profile is a U-ring type single acting seal with symmetrical polyurethane lips. It can be used for both rod and piston applications. It is also called U-Cup seals which are used to seal hydraulic fluid (hydraulic U-cup seals) or air (pneumatic U-Cup Seals), which helps create the pressure necessary for the hydraulic and pneumatic power systems to work.
