O"" Ring - Buna

O"" Ring - Buna

This O-ring is made from Buna-N (Nitrile) rubber, a versatile synthetic material known for its resistance to petroleum-based oils, hydraulic fluids, gasoline, and water. It is a common replacement part for sealing connections in hydraulic lines, fuel systems, and water pumps on general front and rear discharge concrete mixers. Its durability and resistance to abrasion make it a reliable choice for routine maintenance and repairs to prevent leaks in demanding heavy machinery environments.
