Application and properties
Suitable for sealing with rotating or swinging rods, shafts, pins, rotary joints, etc. It is a rotary sealing ring that can withstand both sides pressure or alternating pressure role of the double acting effect, used in construction machinery, construction machinery and automotive equipment. It can be applied on occasions where piston rod and piston seal are required, low friction, non viscous phenomenon, simple groove, good abrasion resistance and dimensional stability.
Standard materials
Sealing ring: filled PTFE
O-Ring: NBR / FKM
