O"" Ring - Buna

O"" Ring - Buna

This O-ring is a circular sealing element made from Buna-N (Nitrile) rubber, one of the most common elastomers used for sealing due to its resistance to petroleum-based fuels, oils, and water. It is designed to be seated in a groove and compressed between two or more parts to prevent fluid or gas loss in concrete mixer systems. This part is a crucial component for routine maintenance and repair of hydraulic systems, water pumps, and other general sealing applications to prevent leaks and ensure equipment reliability. Its material properties provide a durable seal capable of withstanding the demanding environment of concrete mixing equipment.

Key Features

• Made from Buna-N (Nitrile) rubber for excellent resistance to petroleum oils, fuels, and water.
• Functions as a versatile seal for both static and dynamic applications.
• Designed to be compressed in a groove to form a secure, leak-proof seal.
• High tensile strength and good abrasion resistance.
