Q3 U-Cup

Q3 (Rod Seals)

The PDF Ultrathan® Rod Seal Profile Q3 is a compact seal consisting of a fabric reinforced U-Ring with an integral rubber sealing part. The sealing edges at the rubber part remove the film of liquid on the rod surface due to their radial preload. Therefore an excellent sealing performance will be achieved, even at low pressures or in the case of pressure-less movements of the rod. Higher pressures will be transferred to the fabric reinforced U-ring which due to its construction will prevent the possibility of extrusion.

Application:

• Working Pressure: =250 bar

• Working Temperature: -30°C to 100°C (-22°F to 212°F)

• Surface Speed: =0.5 m/s
