Detailed Engineering Specifications

Built to exacting engineering tolerances, this Buna-N (Nitrile Butadiene Rubber) O-ring features an inside diameter of 1.572 inches, an outside diameter of 2.780 inches, and a cross-sectional diameter of 0.136 inches. Buna-N offers excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, making it suitable for moderate temperature applications (typically -40°F to +257°F or -40°C to +125°C). Its inherent resilience and resistance to abrasion contribute to its longevity in static and dynamic sealing applications.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong O-ring material for the fluid or temperature.Always verify the chemical compatibility and temperature range of the O-ring material (Buna-N in this case) against the application's operating conditions.
Overstretching or twisting the O-ring during installation.Install the O-ring carefully, using appropriate tools if necessary, to prevent damage to its surface and ensure proper seating in the groove.

Common Applications

  • Hydraulic Systems
  • Pneumatic Cylinders
  • Fuel and Oil Lines

⚠️ Engineering Warnings

  • Not recommended for use with strong oxidizing agents, ketones, or esters.
  • Exposure to ozone or UV light can degrade Buna-N material over time.
