Thorseals

Thorseals are made of a Thordon proprietary elastomer with no shelf life or degradation of properties over time. They are customized seals to be made for your specific application.

They are used in hard-to-reach wicket gate bearings to prevent contamination by abrasive laden waters or to seal water from entering the plant. They can also be integrated into ThorPlas-Blue bearing designs for easy one-piece installation.

In hydraulic/pneumatic applications, high performance, tough Thorseal self-lubricating polymer lip seals offer positive sealing up to 100 MPa (15,000 psi). Thorseals provide long wear life with no need for periodic adjustments; resist tearing and extrusion; and as a result of their internal lubricants, operate with less drag and reduced cylinder wear. 

Thorseal applications include: Wicket Gate Seals, Kaplan Hub, Servo Motors, Turbine Brake Seals (Cup or Lip style), and to replace rubber or fabric chevron or v-packing sets.
