O"" Ring - Buna

O"" Ring - Buna

This product is a standard AS568-143 O-ring made from Buna-N (Nitrile) rubber, a widely used elastomer for sealing applications in concrete mixers and other heavy machinery. Its specific dimensions are a 2.425-inch (61.60 mm) inside diameter and a 0.103-inch (2.62 mm) cross-section. This type of O-ring is essential for preventing leaks in hydraulic and pneumatic systems, such as pumps, valves, and cylinders, due to its excellent resistance to petroleum-based fluids and abrasion. It is a common replacement part for routine maintenance or repair of hydraulic component seals.

Key Features
