SF Design Packing

The SF Design V-Packing is the most adaptable and popular sealing designs
The single stack SF hinge design permits the sealing lips to remain in contact with the surface being sealed without putting undue stress on the sealing ring itself.
It has an initial interference so adjustment is not required for sealing.
The flexibility of the design allows sealing at a wide range of pressures under almost any condition.
The SF V-Ring is designed with mating surfaces that provide a void between rings, acting as a lubrication reservoir. This design helps retard nesting, allows the rings to relax between cycles and allows lubrication to reach all sealing rings
