Designed for demanding industrial environments, this O-ring features a 3.249" inside diameter, 0.550" outside diameter, and a 0.122" cross-section. The Buna-N elastomer provides excellent resistance to petroleum-based oils, hydraulic fluids, and many other chemicals, while the 304 stainless steel casing offers exceptional corrosion resistance and structural integrity. This combination makes it ideal for high-pressure hydraulic systems, pneumatic assemblies, and fluid handling applications where both chemical compatibility and mechanical strength are paramount.
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 and free of debris. 2. Carefully stretch and place the O-ring into the designated groove, avoiding sharp tools. 3. Verify the O-ring is seated properly and uniformly within the groove before assembly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force or sharp tools during installation, which can nick or cut the O-ring. | Handle the O-ring with care and use a non-marring installation tool or fingertip pressure to seat it. |
| Installing the O-ring into a dirty or damaged groove, leading to leakage or premature failure. | Thoroughly inspect and clean the sealing groove before installation. Repair any damage to the groove if necessary. |
