Company Advantages
1. Since ptfe piston seals technological measures were put forward, hydraulic piston seal 's body frame has been highly improved. Its strength will help to improve extrusions resistance in high-pressure applications
2. Quality for hydraulic piston seal speaks louder than everything in Guangdong DSH Seals Technology Co., Ltd. The low permeability makes it unmatched for service in gaseous media
3. With the assistance of ptfe piston seals, hydraulic piston seal has gained its popularity in the market. Its sealing portion has a simple structure


Y ring has a Y-shaped cross section and is a typical lip seal. Widely used in reciprocating dynamic sealing devices, Y-type sealing ring can be divided into different height lips Y-type sealing rings for shafts, unequal height Y-shaped sealing rings for holes, and shafts according to whether the heights of two lips are the same or not. Hole common contour lip Y seal. The Y ring is mainly used for reciprocating sealing. It is known from its working principle that when the Y ring is installed, the lip must face the high pressure side, and the Y seal ring can only work in one direction.


Features
