Lip seal

roundYpolyurethane

The Y- seal is a typical labial seal. According to the height and width of the section, it can be divided into wide, narrow, Yx and other categories; If the height of the two lips is equal, it can be divided into Y-sealing rings and Y-ring with different lips and Y-shaped sealing rings with aperture. Y- Ring’s cross-section drawing The Y-shaped sealing ring section is Y-shaped, so it is called a Y- ring Y-ring seal is widely used in reciprocating sealing device, its service life is higher than O-ring seal. The applicable working pressure of the Y-type sealing ring is not more than 40MPa, and the working temperature is-30~80℃; Working speed range: 0. 01~0. 6 m/s for polyurethane rubber; 0.05~0.3m/s for polyurethane rubber; 0.01 ~ lm / s. Y-type sealing ring sealing performance, service life and the working pressure limit of different retaining rings, are better than polyurethane rubber material. Y-ring seal features ： (1) Reliable sealing performance (2) Frictional resistance and smooth movement. (3) Good pressure resistance, and a wide range of use pressure. (4) Simple structure, low price. (5) Easy for installation. Y- sealing ring is the most commonly used material is polyurethane rubber, polyurethane rubber Y- sealing ring has good sealing performance, service life and the use of different rings when the working pressure limit is higher
