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. These Loaded Lip Seals are molded from 92 Durometer Urethane with a 70 Durometer Nitrile energizer. The energizer ensures constant pressure on the sealing lips.
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.
