Case Construction Genuine 308036A1 Brake Piston O-Ring “ For Carraro Rear Axle (172 mm ID × 179 mm OD × 3.5 mm Thickness)

The Case Construction Genuine 308036A1 Brake Piston O-Ring is a precision-engineered sealing component used in Carraro rear axle brake piston systems. Its primary function is to maintain hydraulic pressure within the brake piston chamber, preventing oil leakage and ensuring consistent, responsive braking performance.

Manufactured to strict OEM standards, this O-ring is designed to withstand high hydraulic pressure, elevated operating temperatures and repeated braking cycles typical of heavy-duty construction equipment. The accurate dimensions — 172 mm ID × 179 mm OD × 3.5 mm thickness — ensure perfect fitment in Carraro brake housings, eliminating the risk of extrusion, leakage or premature wear.

Using a genuine OEM-spec O-ring is essential during brake overhauls, as it protects critical brake components, maintains system efficiency and helps avoid costly axle and brake failures.
