DAQ2 star double O-combined seal-AQF piston seal (accumulator seals) -5 type Tecom AQ seal - liquid seal

1. Standard material
Seal: PTFE F-PTFE
0-ring: NBR NBR or FKM Viton
Star-ring: NBR NBR or FKM Viton

2 Overview
DAQ2 piston seal is installed in the limited dynamic sealing surface contact points of the star ring elastomer to achieve between the two media, such as liquid / gas force with 0-ring to improve sealing performance. It combines the seal material has a low friction performance and the rubber elastic body a good seal performance, this optimized design greatly reduces the friction, and the leakage can be minimized.

3 Scope of application
DAQ2 piston seal PTFE seals saved low friction, high pressure, high speed characteristics, but also has a rubber sealing characteristics, suitable for a number of high pressure and require faster holding pressure of the occasion.
Can be used as two-way movement of the piston accumulator and position control cylinder, clamping cylinders and other sealing elements can be used in machine tools, presses, mills, shoe machine, piston accumulators, cylinders and other heavy-duty suspension. Especially recommended for heavy and large diameter applications.
Design selection, please refer to Trelleborg company AQ5 series standards.

4 Features and Benefits
1. Good dynamic and static sealing performance;
2. Has the function of holding pressure, fuel tank leakage small;
3. Sliding performance, no crawling;
4. For new environmentally safe hydraulic fluid (bio-oil);
5. As more types of materials can be used, so the adaptability of working conditions;
6. The combination of low friction and high elasticity in one, with a double security;
7. Groove design is simple, small installation space. Grooved dimensions conform to ISO 7425/1, with the cell to circle, Lancaster closure peering;
8. Allows larger extrusion gap, depending upon the application, it can reduce processing costs;
9. Need to be separated in the two media (example: fluid / fluid or fluid / gas) of the occasion, low gas permeability, sealing and high efficiency.
