Detailed Engineering Specifications

Designed for demanding industrial environments, this robust Buna-N O-ring provides reliable sealing across a wide range of operational parameters. The precise dimensions of a 9.794" inside diameter, 9.246" outside diameter, and a 0.165" cross-section ensure a precise fit within mating grooves. Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, greases, and many hydraulic fluids, making it suitable for applications involving petroleum-based media. Its operating temperature range typically spans from -40°F to +257°F (-40°C to +125°C), providing consistent performance under varying thermal conditions. This material's inherent durability contributes to extended service life in high-pressure and dynamic sealing applications.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Installing a dry O-ring.Lubricate the O-ring and groove with a compatible lubricant to prevent friction damage during installation and ensure a proper seal.
Using excessive force during installation.Gently stretch and guide the O-ring into the groove. If resistance is high, re-evaluate the groove dimensions or O-ring size.
Twisting or kinking the O-ring during installation.Ensure the O-ring is seated flat and evenly within the groove to prevent leakage pathways.
