Trusted by engineers across multiple sectors, this Buna-N O-ring is engineered for exceptional sealing performance. Featuring an inside diameter of 2.989 inches, an outside diameter of 2.899 inches, and a robust 0.271-inch cross-section, it offers excellent resistance to oils, fuels, and many hydraulic fluids. Its nitrile butadiene rubber composition provides good abrasion and tear resistance, making it suitable for general-purpose sealing in automotive, industrial machinery, and fluid power systems.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Visually inspect the O-ring and mating groove for any damage, debris, or contamination. 2. Apply a thin, uniform layer of compatible lubricant to the O-ring and the leading edge of the groove. 3. Carefully install the O-ring into its designated groove, ensuring it is seated evenly and not twisted.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade the Buna-N material. | Always use lubricants recommended for Buna-N, such as silicone grease or mineral oil-based lubricants. |
| Forcing the O-ring into the groove, leading to cuts or tears. | Gently guide the O-ring into the groove, using a plastic or wooden tool if necessary, to avoid damaging its surface. |
| Installing a twisted or pinched O-ring, compromising the seal. | Ensure the O-ring lies flat and is not compressed unevenly within the groove before assembly completion. |
