1 in. ID Symmetrical Lip Seal with Polymer-Filled PTFE Jacket

Superior reliability & service life in:

  • Pressure ranges from vacuum to 1500 PSI
  • Temperature ranges from -50 to 250° F
  • Surface speeds to 125 feet per minute

The Symmetrical Lip Seal with Polymer-Filled PTFE Jacket consists of a U-shaped seal jacket with dynamic and static lips of equal size. It is energized with a canted coil spring made from corrosion-resistant 316 stainless steel. The spring helps accommodate for small changes in the seal lip caused by wear, temperature change, or tolerance variations in the assembly. It also ensures effective sealing at startup and low pressures. This radial seal enables bi-directional assembly. It performs well in both piston and housing-mounted applications, and in both rotary and reciprocating service.
