Dear Pr. Hall:
Thank you for inquiring about "Low Friction Rotary Shaft Seals". I'm enclosing a copy of our Seal Selection Guide, describing the advantages of spring-energized Variseal™ and Rotary Varilip® designs.
The Variseal is typically designed into rod, piston, shaft, or face seal applications, especially when service conditions exceed the limits of typical elastomeric seals. The Variseal combines all of the following performance features into one sealing device:
*	Very low friction
*	Complete chemical compatibility
*	High surface speeds
*	Permanent elasticity
*	Food applications
*	Pressures to 30,000 + psi
*	Temperatures from -425 to +575°F
*	Self-lubricating material
*	Unlimited shelf life
*	Inch, metric, and custom sizes
If you would like further information on how the Variseal will work in your application, call us at 1-800-466-1727. Ask for me or for anyone in Technical Support. You can also contact the distributor for your area, Busak+Shamban West, 3904 Del Amo Blvd., Suite 805,, Torrance, CA 90503, (310)371-1025.
Sincerely,
Jacque Rolle
