SRVS Rod Seals
The SRVS rod seal is the combination of a filled PTFE ring (usually 40% bronze-filled) and an energizing O-Ring.
It is a well-adapted part to be used in rods of hydraulic systems such as cylinders, machine tools, injection moulding machines or hydraulic hammers. It should be used in combination with a scraper to provide a great sealing effect.
