Engineered for reliability and performance, this Buna-N O-ring is designed with an Inside Diameter of 7.771 inches, an Outside Diameter of 6.918 inches, and a precise Cross Section of 0.089 inches. The Buna-N (Nitrile) material offers excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a wide range of industrial sealing tasks. The Brass material provides excellent corrosion resistance and compatibility in specific environments where non-ferrous metals are preferred or required. This combination ensures long-term sealing integrity under moderate pressure and temperature conditions.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the groove is clean, dry, and free of debris. 2. Carefully compress the O-ring to fit within the groove, avoiding overstretching or twisting. 3. Verify proper seating and compression for a secure seal.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, which can crush the O-ring and compromise the seal. | Torque fasteners to manufacturer specifications, ensuring consistent pressure distribution. |
| Using incompatible cleaning agents that can degrade the Buna-N material. | Clean the O-ring and groove with mild soap and water or a compatible solvent recommended for Buna-N. |
| Failing to inspect the O-ring for damage or wear before installation. | Visually inspect the O-ring for nicks, cuts, or signs of embrittlement before placement. |
