Company Advantages
1. With the assistance of a team of innovative and experienced designers, DSH piston seal is given a wide variety of design styles. It has moderated cost and good machine-ability
2. Apart from our high quality piston seal , we are highly recognized for our transparent deals and on time delivery of products. Its material makes it extremely tough, yet still flexible enough to be a seal
3. It is checked for its specifications, dimensions, weight, and measurements to ensure the quality. Its materials meet certifications such as ASTM, AMS or FDA compliance
4. The added value of quality and reliability of the product is attributed to the implementation of scientific quality management. It exhibits improved wear performance and tear resistance


A double-acting O-Ring energized seal developed for sealing between two media such as fluid and gas. It incorporates a limited footprint quad-ring Seal inset into the dynamic sealing face. Installed in grooves. Applied to mobile hydraulics, holding cylinders, piston accumulators etc.

DQF combines the characteristics of low friction, high pressure and high speed seals, as well as the excellent sealing of rubber elastomers. Therefore, it is suitable for working at high speeds, high pressures and under pressure.

It can be used as a double-acting piston accumulator to control and guide the cylinder sealing elements. Suitable for machine tools, presses, rolling mills, accumulators and lifting cylinders. Recommended for certain heavy duty and large diameter applications.


Characteristics


  • Low friction and high elasticity, double guarantee

  • High sealing effect in fluid/fluid or fluid/gas

  • Low gas permeability

  • Excellent sliding properties, no stick-slip behavior

  • Can be used under high pressure conditions, good sliding performance

  • Simple groove design

  • Simple installation
