Product Description

ISO/SGS/TUV/MID  Double wiper consisting of one profile ring with one sealing edge and one wiper edge, plus two O-rings as prestress elements.

Materials

PTEE-3 (Filled)PTFE + 40%Bronze
Compared to PTFE-1, this modified grade delivers enhanced compressive strength,improved thermal conductivity,superior wear resistance,and reduced creep making it ideal for dynamic sealing applications.

PTFE-4(Filled)PTFE + 25%Carbon Fiber
PTFE-4 demonstrates enhanced mechanical strength, rigidity, and sliding performance compared to virgin PTFE making it particularly suitable for rotary sealing applications.

Function

Excellent controllability and position ability 


Suited for large diameters

No space for any dirt clusters
The wipers additional static sealing zone(dirt deflector) flush-fits with the housing and leaves no space for any dirt clusters

Good wipe-off sticky dirt
Out standing ability to wipe-off sticky dirt by inherently stable wiper edge.

Reliability sealing system
Improved functional reliability of the completer ability due to thewipers' additional sealing edge.

Stick-slip free
Stick-slip free operation by customisedchoice of materials (friction coefficient)

Application

Double wiper with integrated sealing function towards the outside diameter to improve the sealing functionality of the complete sealing system.
