Loaded Lip Seals are very versatile and can be used as
rod seals or piston seals. They are considered to be
multi-purpose seals and are designed for significantly
improved performance. American Packing Loaded Lip
Seals are molded from 92 Durometer Urethane with a 70
Durometer Nitrile energizer. The energizer ensures
constant pressure on the seaing lips.
Temperature: -65° to +300°F
Pressure: 0 to 5000 psi
Fluids: Petroleum based Hydraulic Fluids
The Standard Loaded Lip Seal is the most widely used design of Loaded Lip
Seal. By energizing the sealing lips with an endless O-ring, you are assured
of uniform, positive lip contact and excellent low-pressure sealing. The seal
depth is equal to the radial width, which results in a square design. Standard Loaded Lip Seals can be widely used to
interchange with existing hydraulic packing and/or O-rings without changing dimensions.
The Loaded Lip Seal Type “B” features a back-beveled sealing lip. This pro-
vides greater film breaking and increased unit loading at the sealing surface.
The seal depth is generally 1 1/2 times the radial width to ensure seal stability
in the most rugged applications. It is most commonly used as a rod seal.
The Loaded Lip Seal – Deep Style incorporates the same unique design as the
Standard Loaded Lip Seal, plus its depth is 1 1/2 times greater than the radial
width. This increases seal stability to withstand rugged, high shock, heavy-duty
applications. This seal will replace many kinds of Vee Packing. When minimum
drag is needed, use Standard Loaded Lip Seals or Loaded Lip Seals – Deep Style. (Note: At the printing of this catalog,
the Deep Style was not a stock item at American Packing, but was readily available. Please inquire.)
