Plunger Packing – Adjustable (SF)

TestingThe SF Design V-Packing is one of the
most versatile sealing
designs on the market today. The single
stack SF design allows 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
