Products Description
Flat face hydraulic O-ring kits, also known as Flat Face O-ring face Seal Fittings, are widely used in modern hydraulic systems to effectively prevent leakage in high-pressure environments. These connectors use hard flat rubber O-rings to achieve a soft seal like a gasket. The O-ring is embedded in a specially machined groove on the connector. When the flat face of the sleeve or tube contacts the face of the connector and the nut is tightened, the O-ring is compressed to achieve a seal.
Flat Face Hydraulic O-Ring Kits-Ideal Mechanical Seal Solution
Features
The flat joint design provides reliable sealing performance under axial compression.
High sealing performance: Flat face hydraulic O-ring kits use high-hardness flat rubber O-rings to provide reliable sealing under high-pressure environments.
Reusability: Unlike flareless fittings that can only be reused a limited number of times, the O-rings of flat face fittings allow unlimited reassembly as long as the O-rings maintain a certain elasticity.
Dynamic sealing: System pressure acts on the statically compressed O-ring, causing it to push outward and temporarily deform, forming a pressure-sensitive dynamic seal.
Application Scenarios
1. Hydraulic systems: widely used in hydraulic equipment and systems that require high-pressure seals.
2. Engineering machinery: hydraulic systems of heavy machinery such as excavators and cranes.
3. Agricultural machinery: hydraulic systems of tractors and other agricultural equipment.
4. Industrial equipment: hydraulic systems of manufacturing, processing, and automation equipment.
5. Automotive industry: used in hydraulic brake systems and other hydraulic control applications.
Material
O-rings and compression washers are usually made of oil-resistant and wear-resistant nitrile rubber (NBR) or fluoro rubber (FKM) and other materials.
Choose rubber materials suitable for the working environment, such as high-temperature resistant silicone rubber (VMQ), chemical-resistant FFKM, etc.
Key Technical Parameters
- Dimensional specifications: Covering various common hydraulic joint sizes, such as metric, imperial, etc.
- Working pressure: generally can withstand the working pressure range of 10-35MPa.
- Working temperature: -40°C to +200°C, depending on the rubber material used.
- Surface roughness: The surface roughness of the connector Ra≤0.8μm, ensuring the smoothness of the sealing surface.
- Hardness: O-rings generally use 70-90Shore A hardness rubber.
