Hydraulic wiper ring HG-TRD


The TRD wiper ring consists of a PTFE element and an O-ring with a sealing effect on the static side and simultaneously activating the effect on the washer at zero pressure.

The TRD seal also functions as a wiper on the outside of the cylinder and retains the lubricating layer on the inner side of the stem.

The use of this type of TRD in combination with a correctly selected other seal ensures the hydrodynamic return of the cylinder.

Technical specifications:

Speed: < 15 m/s.

Temperature: from -30°C to + 100°C for the standard type O-ring made of NBR material.

Maximum permissible temperature +120°C, -15°C to +50°C for O-rings made of FKM material.


Name: PTFE material filled with bronze - for standard type and NBR material for O-ring.

Material code: TN.


Installation is carried out in a semi-open landing groove.

It is recommended that you first mount the O-ring into the landing groove, then the PTFE.

It is necessary to observe the permissible value of the surface roughness (the landing groove).
