PTFE Seals-type PC
Seal sets of type RO and PO can be used in hydraulic applications in place of dynamically stressed O-rings. Existing grooves can be used as fitting area if they conform to the US standard AS 568A.
These seal sets enable the dynamic behavior to be improved, as a result of which higher gliding speeds, smoother running properties and higher wear resistance are attained. PTFE Glide Seal sets can also be used in O-ring fitting areas designed for one or two back-up rings.
Care must be taken in the design to ensure that the groove width L is selected according to the number of back-up rings. The standard material combination is modified PTFE and NBR (O-ring).
A unique piston seal is design to retrofit standard O-ring gland in bi-directional pressurization, hydraulic applications. It benefits higher extrusion resistance, excellent chemical resistance, and no stick-slip movement even in low velocities.
