Pneumatic Z-type Seals Can Replace Two Y-type Seals?

In order to improve the service life of seals, the contact area and contact pressure between seals and moving parts must be reduced. Dongsheng Seal tells you that at present, Japan has developed a Z-shaped seal (English Z seals) made of high-quality oil resistant and wear-resistant rubber, which can replace two Y-shaped seals. Its key point is excellent flexibility. The contact part with the moving parts is ridge shaped. The contact area and friction are small, and the self lubrication effect is strong. It is not affected by the fit clearance. Z-shaped seals are suitable for sealing moving parts under low pressure.
