Detailed Engineering Specifications

A proven choice for industrial professionals, this Buna-N O-ring features an Inside Diameter of 9.674 inches, an Outside Diameter of 4.843 inches, and a precise Cross Section of 0.205 inches. While Buna-N (Nitrile) is a common elastomer known for its excellent resistance to oils, fuels, and hydraulic fluids, its application in conjunction with a Titanium Grade 5 material is highly specialized. Titanium Grade 5 (Ti-6Al-4V) offers exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility. This combination is typically employed in extreme environments where both chemical inertness and mechanical integrity are paramount, such as aerospace, advanced medical devices, or highly corrosive chemical processing.
