FAB PISTON CUP 2 OD X 1/2 X 1/8 X 1/2 CH

APG stocks the K203-500, a Buna-N (Nitrile) U-Cup Seal with a 1/2 in inside diameter, a 2 in outside diameter, and a height of 1/8 in. An u-cup seal uses a U-shaped profile that system pressure forces outward, tightening the seal as pressure rises. Supplementary detail from the product record: With 1/2 ID Hole IN Center.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. This material stands up to hydraulic fluids, many alcohols, and petroleum-based oils. Verify compatibility before use with polar solvents or automotive brake fluid.

Maintenance and OEM teams specify it across agricultural equipment, general industrial maintenance, and fluid power.

K203-500 ships individually. Review your operating media and conditions against this specification before installation.
