Therefore, it is always advisable to test the material under actual service conditions before specification. If this is not practical,tests should be devised that simulate service conditions as closely as possible.Parker EPS Division also offers unique material blends and recipes along with a wide variety of other PTFE filler combinations andcolors to enhance seal performance in the most extreme application needs. For guidance on material selection for extremeapplications, please contact an EPS Division PTFE Application Engineer at 801-972-3000.* Since surface speed, pressure, under-lip temperature, media lubricity and abrasiveness significantly affect the level of shaft hardnessneeded in an application, the user should upgrade from these recommended minimums as the application becomes more severe.03/28/069-8 Parker Hannifin CorporationEPS DivisionToll Free: (800) 233-3900www.parkerseals.com
