Key Features

  • Loaded lip seal for providing a hydraulic-cylinder seal under varying pressures up to 5,000 pounds per square inch (psi)
  • Rectangular profile to provide a seal in heavy duty industrial equipment and hydraulic applications
  • Lip seal made from urethane for flexibility and resistance to impact, abrasion, and hydrocarbons
  • O-ring made of Buna-nitrile (also called Buna-N) for use with a variety of fluids from petroleum to aliphatic hydrocarbons
  • Functions in temperatures from -40 to 200 degrees F and has a durometer of 92A

Product Description

This loaded lip seal has a rectangular profile, is made of black urethane, has a black Buna-nitrile (Buna-N) O-ring, functions in temperatures from -40 to 200 degrees F and has a durometer of 92A.

Urethane is a lightweight plastic with impact, abrasion, weather, electrical, and hydrocarbon resistance. It is available in different levels of hardness depending on the application, and performs well up to about 90 degrees C (194 F). Buna-nitrile can have high tensile strength, and has abrasion, tear, and compression set resistance. It is compatible for use with petroleum, hexafluoroacetone (HFA), hexafluoro-2-butyne (HFB) and hydrofluorocarbon (HFC) fluids, vegetable oil, alcohol, acids, and aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering, and should not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.

The durometer hardness of this lip seal is 92A. Durometers measure the hardness of a material and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation. On a scale of 0 to 100, a value of 0 indicates that a sample was completely penetrated, while a value of 100 shows no indentation in the sample. The letter following the number identifies the shore scale, which is either shore A or D. Shore A is used for softer plastics, while shore D is used for harder plastics.

Rectangular profile lip seals, also known as Type B seals, provide a pressure and fluid seal in heavy duty industrial equipment and hydraulic applications. They are circular in shape, with a rectangular cross section for providing a static seal under high pressure, and a u-shaped indentation for holding an O-ring (which helps alleviate pressure on the inner and outer diameter seal surface and to prevent leakage in dynamic applications at lower pressures). They have beveled edges, for squeezing into small applications and less leakage. O-rings provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders. They are circular in shape, with a round cross section, and a hole in the center, similar to a doughnut. Lip seals are available in different heights, widths, and with different inside and outer diameters.
