High-Pressure Leather U-Cup Seal

Manufacturer part: 1704N13

Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups. Leather is tough, pliable, and wear resistant, so it flexes to fit uneven surfaces and fill voids. U-cups can be used for rod and piston sealing. Pistons require two seals—install one facing in each direction.Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
