The Graco 00158B Buna-N O-Ring 231 70A is a precision-engineered sealing component designed for high-pressure fluid systems used in professional spraying and coating applications. Manufactured from Buna-N (Nitrile), this O-ring delivers reliable resistance to petroleum-based fluids, hydraulic oils, and common industrial solvents. With a hardness rating of 231 70A, it ensures optimal balance between flexibility and compression strength, making it suitable for demanding Graco pump environments.
This sealing element plays a critical role in maintaining pressure integrity within pump housings and fluid sections, helping reduce leakage, extend equipment life, and maintain consistent spray performance. It is commonly used in service kits and maintenance rebuilds where OEM specifications require exact replacement parts.
The Graco 00158B Buna-N O-Ring 231 70A is a circular elastomer seal designed to fit precisely into grooves within Graco fluid handling equipment. It functions as a compression seal, preventing fluid leakage between mating components under pressure. Made from Buna-N, it offers strong resistance to wear, abrasion, and petroleum-based chemicals commonly found in paint and coating systems.
The designation 231 70A refers to its size specification and Shore A hardness rating, indicating a medium-firm elastomer ideal for dynamic and static sealing applications in industrial pump systems.
