DSF is composed of PTFE seal ring and O-ring. It is used for double acting sealing of the piston rod of the hydraulic cylinder. Due to adopting special modified PTFE material, it can guarantee excellent low friction, wear resistance, extrusion resistance, high-temperature resistance and Chemical resistance.

DSF is a very effective and reliable low friction seal. It is particularly suitable as a piston seal in high pressure and low pressure systems. It contains a PTFE ring that is reinforced with creep-resistant additives and preloaded through O-rings to be effective over the recommended working pressure range. As the pressure increases, the O-ring deforms and presses the PTFE ring against the tube wall, increasing the sealing force and sealing effect. Since only the PTFE ring is in contact with the sliding surface, the friction is very low and the stick-slip motion is eliminated.

The Glyd ring ensures a good static seal and allows the lubricated hydrodynamic oil film to be built under seal in reciprocating applications.

Features:These are very effective in sealing heavy loads up to 500 bar and minimal stick/slip, and surface speeds up to 15 meters per second in reciprocating motion. The temperature range can be from -50 ° C to 200 ° C depending on the material used for the "O" ring of the exciter. The seal is made of bronze filled or carbon filled PTFE.
