Y-ring characteristics:

　　1) reliable sealing performance

　　2) small friction, smooth motion.

　　3) the pressure is good, use a wide range of pressure.

　　4) The structure is simple and inexpensive.

　　5) ease of installation.

　　Y-ring disadvantages?

　　1) The main drawback of the Y-shaped seal is only one-way function, piston type bidirectional sealing need to use a pair of Y-shaped seal ring to increase the axial dimension;

　　2) the normal Y-shaped ring of the cross-sectional dimensions greater than the O-rings, so the installation groove dimensions larger, sometimes need to use a split groove in order to facilitate the installation. Now many countries are developing a Y-shaped ring of small cross-sectional dimensions, size and installation is gradually improving.

　　Y-ring performance

　　The Y-shaped seal is a seal reciprocation sealing means commonly used in hydraulic and pneumatic systems, and its life and sealing performance are higher than the O-ring seal. Y-shaped ring lip than a single V-ring width, better sealing performance, simply use a so friction is less than the V-ring. The Y-shaped seal to adapt to the requirements of the pressure and sealing performance by changing the cross-sectional structure and dimensions. Y-ring applicable working pressure of not more than 40MPa; Operating Temperature -30 to 80 ° C; operating speed range; nitrile rubber production of 0.01 to 0.6m / s when using polyurethane rubber production, compared with 0.05 ~ 0.1m / s.
