Y type seal specification

The cross-section of the Y-shaped sealing ring is Y-shaped and is a typical lip-shaped sealing ring. It is widely used in reciprocating sealing devices, and its service life is longer than that of O-rings. The applicable working pressure of the Y-shaped sealing ring is not more than 40MPa, and the working temperature is -30~80℃.

According to the length and width ratio of the cross section, the Y-type sealing ring can be divided into a wide-type Y-type sealing ring, a narrow-type Y-type sealing ring and a Yx-type sealing ring. The pressure resistance of the wide-section Y-seal is slightly smaller than that of the narrow Y-seal, and can only be used in the working environment of P<20MPa, while the narrow Y-seal can be used in the case of the working pressure of P<32MPa.
According to whether the height of the two lips is the same, the Y-shaped seal can be divided into the unequal-height lip Y-seal for shaft and the unequal-height lip Y-seal for bore. Y-rings with contour lip for common shaft bores. Y-Seals are made of different materials, and can also be divided into nitrile rubber Y-seals, fluororubber Y-seals, polyurethane rubber Y-seals, etc.
Working speed range: 0.01~0.6m/s when made of nitrile rubber; 0.05~0.3m/s when made of fluororubber; 0.01~lm/s when made of polyurethane rubber. The sealing performance, service life and working pressure limit of different retaining rings are all made of polyurethane rubber.

1) Reliable sealing performance;
2) Small frictional resistance and smooth movement;
3) Good pressure resistance and a wide range of applicable pressures;
4) Simple structure and low price;
5) Easy to install.
