Designed for demanding industrial environments, this Buna-N O-ring features a 6.872-inch inside diameter, a 3.826-inch outside diameter, and a 0.175-inch cross-section. The 316 stainless steel construction provides superior corrosion resistance, making it ideal for aggressive media and elevated temperatures. This material combination ensures excellent chemical compatibility with a wide range of oils, fuels, and hydraulic fluids, while the Buna-N elastomer offers good abrasion resistance and a broad service temperature range. Its tight tolerances contribute to leak-proof performance in critical sealing applications.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the sealing groove is clean, free of debris, and within specified dimensional tolerances. 2. Carefully inspect the O-ring for any nicks, cuts, or imperfections before installation. 3. Lubricate the O-ring and the sealing groove with a compatible lubricant to prevent damage during assembly and ensure proper seating.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Installing a dry O-ring, leading to tearing or stretching. | Always lubricate the O-ring and groove with a compatible lubricant. |
| Using excessive force, causing O-ring damage or improper seating. | Apply gentle, even pressure during installation, ensuring the O-ring rolls into the groove without pinching. |
| Incorrect O-ring size for the groove, resulting in leaks or extrusion. | Verify O-ring dimensions and groove specifications meticulously prior to installation. |
