O"" Ring - Buna

O"" Ring - Buna

This is a standard O-ring seal manufactured from Buna-N (Nitrile) rubber, one of the most common sealing elastomers used in machinery. It is designed to be seated in a groove and compressed between parts to create a reliable seal against fluid or gas loss. Due to its excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, this O-ring is ideal for various applications within concrete mixer hydraulic and pneumatic systems. It serves as a critical replacement part during routine maintenance or repair of components like pumps, valves, and cylinders to prevent leaks and ensure operational integrity.

Key Features

• Made from Buna-N (Nitrile) material for broad application use.
