Designed for demanding industrial environments, this Buna-N O-ring features a precise 1.217" inside diameter, a 7.876" outside diameter, and a 0.080" cross-section. The Buna-N (Nitrile Butadiene Rubber) compound provides excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a wide range of sealing tasks. Its carbon steel construction offers enhanced structural support and resistance to compression set, ensuring long-term performance in applications such as hydraulic systems, pneumatic cylinders, and general fluid power equipment.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Inspect the groove and mating surfaces for cleanliness and damage. 2. Carefully install the O-ring into the designated groove, ensuring it is seated without twisting. 3. Apply a thin layer of compatible lubricant to the O-ring and mating surface if recommended for the application.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, which can deform or extrude the O-ring. | Adhere to recommended torque specifications for all fasteners. |
| Installing a twisted O-ring, leading to immediate leakage and premature failure. | Ensure the O-ring is laid into the groove without any twisting during installation. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Always consult material compatibility charts for appropriate lubricants and cleaning solutions. |
