hydraulic fittings o ring face seal

Annular sealing is an important sealing device in hydraulic systems, typically used in hydraulic fittings, joints, and connectors to ensure the sealing performance of the hydraulic system. Annular face seals are usually made of different materials, with different sealing characteristics and application ranges. The following are some common annular sealing hydraulic accessories in hydraulic accessories:

O-ring: O-ring is one of the most common ring face seals used to seal the interfaces of hydraulic connectors, valves, pistons, cylinder bodies, and other hydraulic accessories. It is usually made of rubber materials such as NBR, Viton, EPDM, etc. O-ring is widely used in hydraulic systems, with good oil resistance and sealing performance.

U-shaped seal: A U-shaped seal is a sealing ring with a U-shaped cross-section used to seal the piston rod or piston rod head of a hydraulic cylinder. They are often used in high-pressure hydraulic systems and can resist large lateral forces and pressures.

V-shaped seal: V-shaped seal is also used to seal the piston rod or piston rod head of hydraulic cylinders. They have a V-shaped cross-section and are typically used to resist contamination and liquid leakage.

Buffer seal: Buffer seal is usually used in the buffer area of hydraulic cylinders to reduce the impact and vibration of the piston under extreme conditions. They help extend the lifespan of hydraulic cylinders.

Oil seal: Oil seal is used to seal bearings of rotating components in hydraulic systems, such as hydraulic motors and pumps. They can prevent liquid leakage and prevent external impurities from entering the hydraulic system.

Flat sealing: Flat sealing is used to seal connectors and flanges in hydraulic systems, ensuring that liquid does not leak. They are usually made of metal or rubber and have a flat sealing surface.

Thread sealing: Thread sealing is usually used for hydraulic fittings connected by threads, such as hydraulic pipe joints. They provide sealing performance in the threaded part.
