Description

Glyd ring piston seal DSF is composed of PTFE seal 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.

Glyd ring 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 comprises a PTFE ring, strengthened with additives to resist creep, which is pre-loaded by an O ring to be effective for the operating pressure range recommended.

As the pressure rises the O ring deforms and compresses the PTFE ring against the tube wall increasing the sealing force and the effectiveness of the seal. As only the PTFE ring is in contact with the sliding surface, friction is very low and stick-slip movement is eliminated.
