DDAS combination seal - DAS combination seal - KDAS combination seal - TPM combination seal - ZX piston seal - KGD combination seal - GDAS piston seal
1. Standard materials
Sealing body: Nitrile rubber NBR or fluororubber FKM
Retaining ring: polyester elastomer
Wear ring: Polyoxymethylene POM or nylon PA
2. Application scope
DDAS combination seals are often used as sealing components in hydraulic cylinders and pistons that move back and forth, such as bulldozers, cranes, forklifts, hydraulic gates, and agricultural machinery. Installed in closed trenches including ISO6547 standard trenches. When designing and selecting, reference can be made to Trelleborg's DAS series, Parker's ZW series, and AS's KGD series standards.
3. Features and advantages
1. Good anti leakage performance;
2. The elastic sealing ring will not twist or flip;
3. The total length of the piston is relatively short;
4. The production cost of the piston is low;
5. The sealing ring and wear-resistant ring are inexpensive;
6. The notched retaining ring and guide ring are easy to install;
7. Extremely strong resistance to extrusion of gaps;
8. It can be installed in closed grooves, which can reduce processing costs.
