Are hydraulic fittings equipped with sealing rings or sealing gaskets?

Hydraulic fittings typically come with sealing rings or sealing gaskets to ensure the system's integrity. These sealing components play a crucial role in hydraulic fittings, effectively preventing fluid leakage and ensuring proper operation in high-pressure and high-temperature environments.

Sealing rings are one of the most common sealing components in hydraulic fittings and are usually made from rubber or other elastic materials. The most common type is the O-ring, which has a circular cross-section and forms a tight seal between two mating surfaces to prevent fluid leakage at the connection point. The elasticity and precise fit of O-rings allow them to adapt to pressure changes in the system and maintain a stable sealing performance. In some cases, V-rings, which have a V-shaped cross-section, are also used. These are suitable for high-pressure environments and can provide additional sealing performance, especially under extreme conditions.

Sealing gaskets are also important components in hydraulic fittings, typically used to fill gaps between connections and ensure a tight seal. Common sealing gaskets include flat gaskets and copper gaskets. Flat gaskets are usually made from soft materials like rubber, fiber, or paper and effectively seal gaps between fittings to prevent fluid leakage. Copper gaskets, made from copper, are suitable for high-temperature and high-pressure applications and provide excellent sealing performance and temperature resistance, particularly where additional durability is needed.

Additionally, some hydraulic fittings may use metal sealing components, such as metallic ring seals. These are designed to maintain stable sealing performance under high pressure and temperature conditions. Metal seals can withstand significant pressure and temperature fluctuations while maintaining good sealing capability.

Overall, sealing rings and gaskets in hydraulic fittings use various materials and designs to meet the sealing requirements of different operating conditions, ensuring the stable operation and long-term reliability of the hydraulic system. Choosing the appropriate sealing components and proper installation is key to preventing fluid leakage and ensuring the system functions correctly.
