Detailed Engineering Specifications

A high-performance industrial component, this Buna-N O-ring is precisely manufactured with an inside diameter of 7.523 inches, an outside diameter of 9.945 inches, and a cross-section of 0.118 inches. The Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to petroleum-based oils, hydraulic fluids, and fuels, while the carbon steel construction provides superior rigidity and resistance to deformation under pressure. This combination makes it ideal for applications requiring a durable and reliable seal in environments with moderate temperatures and exposure to common industrial lubricants.
