Pneumatic seal commonly used sealing rings include O-ring, Y-ring, V-ring, U-ring, hole with YX sealing ring and YX hole with retaining ring. Here are the details:
An O-ring. This is a circular sealing ring, with good sealing and wear resistance, suitable for low and medium pressure conditions. 24
Y-shaped circle. This kind of sealing ring is made of fluorine rubber, butyl rubber, chlorine rubber and other materials, widely used in hydraulic and pneumatic industry. 1
V-shaped ring. This is an axially acting elastic rubber sealing ring for non-pressure sealing of the rotating shaft to prevent internal grease or oil from leaking out. 134
U-shaped ring. This kind of sealing ring has good elasticity and adaptability, and is mostly used to seal connections in a small range. 3
Hole with YX sealing ring. The sealing ring is used to seal the piston in the reciprocating hydraulic cylinder, and is suitable for general hydraulic cylinder and general equipment hydraulic cylinder.
Stopper ring for YX hole. This sealing ring is suitable for use with YX type sealing ring when the working pressure of the cylinder is greater than 16MPa.
In addition, there are other application-specific seals, such as piston rings, piston rod seals, rotor seals and static seals, which are used in cylinders, pneumatic cylinders, gas centrifuges and high-pressure gas and hydraulic systems. When selecting pneumatic seals, it is necessary to select the appropriate material and type according to the specific application environment and media, and pay attention to its installation and maintenance
