72 x 80 x 12 Polyurethane Piston U-Cup - Metric

MA28 series metric urethane U-cups are non-symmetrical in design and are meant to be used only for reciprocating piston seals. They are manufactured slightly smaller in diameter than nominal dimensions. This ensures a tight fit when snapped over the piston. Good stability and decreased heel drag, resulting in lower friction, are the prime features of this seal.
Temperature: -40°F to 230°F
