3. Application and Properties  
For reciprocating system, especially in low temperature, high frequency and heavy dust conditions. Mainly applied to hydraulic and pneumatic devices, servo system, chemical and food machinery. Excellent sliding performance, no stick-slip behavior, no viscosity, compensates to the distortion of pistons and plungers, excellent compatibility of hydraulic mediums,excellent effect of scraping residue oil films of the rod surface from inside.

 

4. Standard materials

O-ring: NBR / (Standard) FKM (available on request)

Sealing ring: filled PTFE
