Specified by design engineers worldwide, this industrial O-ring features a 7.484-inch inside diameter, a 5.231-inch outside diameter, and a 0.258-inch cross-section. Constructed with Buna-N (Nitrile Butadiene Rubber) for exceptional resistance to oils, fuels, and many hydraulic fluids, and a brass element for enhanced rigidity and chemical compatibility in specific systems. This combination makes it ideal for static and dynamic sealing in moderate-pressure applications where petroleum-based fluids are present.
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 properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the component, avoiding undue stress or sharp edges. 3. Seat the O-ring evenly within the groove, ensuring it is not twisted or pinched.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fittings, leading to O-ring extrusion or compression set. | Tighten fittings to the manufacturer's specified torque. Use backup rings if pressure is high. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Always consult a chemical compatibility chart for Buna-N and select lubricants/cleaners accordingly. |
