Polymer Rotary Lip Seals

Polymer Rotary Lip Seals

Polymer rotary lip seals are designed to replace conventional elastomeric lip seals where operating conditions exceed their performance capability. The all polymer seal does not require tooling that a metal-encased lip seal does so it is an economic seal selection for housings that are suitable to retain the polymer seal without a metal case.

Why use polymer ROTARY lip seals?

  • Wide operating temperature range -65°F to 450°F (-54°C to 232°C)
  • Temperature below 32°F (0°C)  or above 200°F (93°C) requires a metal insert support ring
  • Can be used in a variety of conditions and environments
  • Increase operating capability compared to oil seals up to 250 psig.
  • Cost-saving compared to mechanical face seal
  • Long seal life
  • Low frictional torque
  • Chemical resistance


Polymer rotary lip seals are available in many different Duron® materials and are specified based on your conditions and parameters. For a complete proposal, submit a Request for Quote and we will respond immediately.

Polymer Rotary Lip Seals Single Polymer Lip Seal Single polymer lip seal offers premium performance at an economical cost. The seals are suitable for liquids or gasses at lower pressures, low or moderate shaft speeds up to 750 surface feet per minute. Operating temperatures under 200°F (93°C). Pressure under 75psig. RFQ
Polymer Rotary Lip Seals Single Polymer Machined Lip Seal. Single polymer machined lip seals are used small diameter shafts under an inch. The seal offers improved frictional performance. RFQ
Polymer Rotary Lip Seals Single Polymer Low Torque, Lip Seal. Single polymer low torque lip seal offers extra low rotary friction in low torque applications. It can seal either liquids or gasses at very low pressures.  RFQ
Polymer Rotary Lip Seals Single Polymer Lip Seal with Garter Spring Single polymer lip seal with garter spring seals offer improved sealing when shaft run-out is high or when a drip-proof seal is required. Best with lubricant fluids, but can be used with other media at reduced speeds. RFQ
Polymer Rotary Lip Seals Dual Polymer Lip Seal Dual polymer lip seal is capable of sealing at pressure differentials up to several hundred psi. The metal insert also increases the operating temperature capability. This stainless steel insert band should be specified on any application with operating temperature. RFQ
