Scope of application

DAQ2 piston seal retains the low friction, high pressure resistance and high speed characteristics of PTFE seals, and has the sealing characteristics of rubber, which is suitable for some occasions with high speed and high pressure and need to maintain pressure.

It can be used as a two-way motion piston accumulator and a sealing element for position control cylinders, clamping cylinders, etc., and can be used in machine tools, presses, rolling mills, shoe machines, piston accumulators, heavy suspension cylinders, etc. Especially recommended for heavy duty and large diameter applications.

 Features and Benefits

1. Good dynamic and static sealing performance;

2. With the function of maintaining pressure, the leakage in the cylinder is small;

3. Good sliding performance, no crawling;

4. Hydraulic fluid (bio-oil) suitable for new environmental protection and safety;

5. Since a wide variety of materials can be used, it has strong adaptability to working conditions;

6. It combines low friction and high elasticity, with double safety;

7. The groove design is simple and the installation space is small. The groove size conforms to ISO 7425/1, and can be interchanged with Glynn, Sterling, etc.;

8. Larger extrusion gap can be allowed, depending on the application, so the processing cost can be reduced;

9. Where two media need to be separated (eg: fluid/fluid or fluid/gas), the gas permeability is low and the sealing efficiency is high.
