Description
Precision Sealing Solution: Metric O-Ring (3.85mm ID x 2mm Thick)
Engineered for critical sealing applications, this industrial-grade O-ring delivers exceptional performance in high-pressure and temperature-sensitive environments.
Technical Specifications:
– Inner Diameter: 3.85mm ±0.05mm
– Cross Section: 2mm (±0.08mm tolerance)
– Material: ISO-certified Nitrile Buna-N (70 Shore A)
– Pressure Rating: 3000 PSI (continuous) / 5000 PSI (burst)
– Temperature Range: -40°C to +120°C (-40°F to +248°F)
Optimized Use Cases:
▸ Hydraulic cylinder piston seals in construction equipment
▸ Fuel system gaskets in marine engines (-40°C cold starts protected)
▸ High-vacuum chamber seals in laboratory settings (0.1 micron leakage rate)
▸ Automotive timing belt covers (resists engine oil degradation)
Performance Advantages:
| Specification | Standard O-Rings | Our Metric Series |
|---|---|---|
| Dimensional Accuracy | ±0.15mm | ±0.05mm |
| Chemical Resistance | Petroleum only | ASTM D4157 Class A (oils, fuels, coolants) |
| Compression Set | >35% after 70h | <12% after 70h |
| Shelf Life | 24 months | 36 months |
The proprietary vulcanization process ensures consistent elasticity across temperature extremes – maintaining 85% rebound rate after 10,000 compression cycles (-20°C test environment). Ideal for ISO 9001-certified manufacturing requiring traceable sealing components (batch numbers included with every order).
Packaged in moisture-resistant anti-static bags with embedded RFID tags for inventory management, these metric O-rings meet AS568A specifications and are direct replacements for Parker Hannifin Series 7125 and Freudenberg V-Seal variants.
