Product Detail
When considering a rotary service seal and additional gland length is available, an O-Ring Heel Seal provides a level of anti-rotation and redundant sealing. The addition of an O-Ring on the heel of a radial seal creates a high friction interface at the bore to counteract rotary forces. With proper hardware design, a high level of sealing can be realized, making an O-Ring Heel Seal a good choice where gaseous or low viscosity fluids need to be sealed. Single-Lip V-Spring-loaded rotary shaft seal for extreme environments.
This seal is designed to provide long service life and low friction for extreme service applications over a wide temperature range.
This seal is for high PV applications characterized by high pressure and low speed. This seal has a relatively small axial length and is available in many materials specially suited to handle aggressive chemicals and environments.
Common Materials Used in this Product
Graphite Filled
Since graphite is often used as a lubricant, it does not significantly increase the coefficient of friction of PTFE when used as a filler. The low friction allows the compound to be used when both shaft speed and pressure are high. Graphite also is chemically inert which enables its use in corrosive medias.
Proprietary Low Wear PTFE
This proprietary filled PTFE offers low wear and friction properties, used in general applications where long life is required. Not recommended for applications with abrasive media.
Molybdenum Disulfide and Fiberglass Filled
Molybdenum disulfide increases the hardness of the seal surface while decreasing friction. It is normally used in small proportions combined with other fillers such as glass. MoS2 is also inert towards most chemicals.
Carbon Fiber Filled
Carbon fiber lowers creep, increases flex and compressive modulus and raises hardness. Coefficient of thermal expansion is lowered and thermal conductivity is higher for compounds of carbon fiber filled PTFE. Ideal for automotive applications in shock absorbers and water pumps.
