"SF" design V-Packings are one of the most popular sealing designs on the market today. The unique design seals well in reciprocating, centrifugal, and static applications. The flexibility of the design allows the "SF" rings to seal at a wide range of pressures under almost any conditions.

The "SF" design seal rings incorporate a hinge-like feature in the center of each ring. This hinge area allows the sealing lips to remain in contact with the surface being sealed without putting undue stress on the sealing ring itself. The "SF" design seal ring is designed with mating surfaces that provide a void to exist between rings acting as a lubrication reservoir. This design helps retard nesting, allows rings to relax between cycles, and allows lubrication to reach all sealing rings.

"SF" V-Ring sets are available packaged in complete sets or on an individual component basis. Materials include homogeneous elastomers, fabric/rubber composite, polyurethane, and PTFE. Special compounds are available as well. Contact Fluid Sealing Service for more information.
