MA28 - URETHANE ASYMMETRICAL 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 Pressure: 0 to 5000 psi
