Goodrich Wheel & Brake Rubber Seal 68-1157 OEM Replacement

The Goodrich Wheel & Brake 68-1157 is a rubber seal intended for aircraft wheel and brake assembly applications. Manufactured in the United States under CAGE code 97153, this seal is available as a direct OEM replacement and carries ECCN 9A991.d. It is 8130-3 eligible for use in FAA-regulated maintenance programs.

Rubber seals in aircraft brake systems provide hydraulic fluid containment within the brake piston bore, preventing leakage and maintaining consistent brake actuation pressure through the pressure cycling associated with repeated brake applications. The sealing element must resist aircraft hydraulic fluids (MIL-PRF-5606 or MIL-PRF-83282 as applicable), operating temperatures at the brake, and the mechanical compression and relaxation cycles occurring with each brake application and release. Failure to maintain seal integrity can result in reduced braking effectiveness or fluid loss. The 68-1157 measures 2.50 x 2.50 x 0.24 inches and weighs 0.03 lb. This seal is packaged individually. HTS code is 4016930000, consistent with vulcanized rubber sealing products for aerospace applications.
