Products Overview
1. Product Overview
In the challenging field of oil exploration drilling, valve stem sealing is critical. Our company's rubber seal Y-ring is specially designed for oil exploration drilling valve stems and is a key component to ensure efficient and safe operation of equipment. It provides reliable sealing solutions for your oil exploration operations with excellent performance in extreme working environments.
2. Product features
- Precise fit: Tailor-made according to the precise dimensions and unique working conditions of the oil exploration drilling valve stem to ensure a tight fit and no leakage hazards.
- High-quality rubber material: Made of selected oil-resistant, high-temperature-resistant, and high-pressure-resistant rubber, such as fluorine rubber, etc., it has excellent anti-aging and chemical corrosion resistance and can operate stably for a long time in harsh oil drilling environments.
- Efficient sealing performance: Unique Y-shaped structural design, the lip is in close contact with the valve stem, forming multiple sealing lines of defense, effectively blocking the leakage of drilling fluid, oil and gas and other media, with excellent sealing effect.
- Low friction resistance: While ensuring the sealing effect, the optimized rubber formula and surface treatment reduce the friction coefficient during valve stem movement, reduce wear, extend the service life of the valve stem and seals, and improve the flexibility of valve operation. and response speed.
- Strong extrusion resistance: The special rubber material and structure enhance its extrusion resistance. Even under high pressure differential conditions, it can maintain a complete sealing form and prevent the seal from being extruded and failing.
3. Technical parameters

Products Description
| Performance parameters | Details |
| Material | Fluorine rubber (FKM) |
| Shore hardness | 70 degrees |
| Temperature resistance range | -20℃-200℃ |
| Chemical resistance | It has good tolerance to oil, natural gas, various drilling fluids (including corrosive components such as acids and alkalis), and complex underground chemical substances. |
| Pressure resistance | Generally it can withstand high pressure, up to tens of MPa (the specific value is affected by factors such as size) |
| Sealing performance | Under low pressure, it relies on the elasticity of the lip to provide an initial seal. Under high pressure, the medium pressure prompts the lip to further compress the valve stem to achieve better sealing. The self-tightening sealing characteristics are good. |
| Friction characteristics | The friction resistance is small during the reciprocating movement of the valve stem, which can adapt to the eccentric movement of the valve stem and reduce wear on the valve stem. |
| density | About 1.8 - 2.0g/cm³ (the specific value may vary slightly depending on the formula) |
| Shrinkage | The linear shrinkage after vulcanization is generally around 2% - 4% (affected by vulcanization conditions and other factors) |
