A proven choice for industrial professionals, this Buna-N O-ring offers superior sealing integrity. Featuring an Inside Diameter (ID) of 5.367 inches, an Outside Diameter (OD) of 1.479 inches, and a precise Cross Section (CS) of 0.191 inches, it's manufactured from high-quality Nitrile Butadiene Rubber (NBR). This material exhibits excellent resistance to petroleum-based oils, hydraulic fluids, greases, and water, operating effectively within a temperature range of -40°F to +257°F (-40°C to +125°C). Its inherent resilience and compression set resistance ensure long-term sealing reliability in dynamic and static 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, dry, and free from debris. Lubricate the O-ring lightly with a compatible lubricant if specified. 2. Carefully install the O-ring into the groove, ensuring it is not twisted or cut by sharp edges. 3. Verify proper seating and absence of damage before assembling the mating components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong O-ring size for the groove. | Always verify the O-ring dimensions (ID, OD, CS) against the groove specifications to ensure a proper fit and seal. |
| Twisting or nicking the O-ring during installation. | Handle the O-ring with care and avoid stretching it excessively. Use appropriate tools if necessary and ensure all mating surfaces are smooth. |
| Using incompatible lubricants or sealants. | Refer to the chemical compatibility chart for Buna-N to select a lubricant or sealant that will not degrade the O-ring material. |
