11Catalog EPS 5350/USAIntroductionFlexiLip, FlexiCase and FlexiSeal ®FlexiLip, FlexiCase and FlexiSeal PTFE seals extend theParker application range by providing coverage whereoperating conditions exceed the capabilities of elastomeric lipmaterials. Conditions such as high speed and high pressure,and requirements for chemical resistance and low torque areeasily accommodated by one of our 50 standard profiles.The typical size range is for shaft diameters from 0.125"(3 mm) to 16" (406 mm).ProTech Bearing IsolatorsProTech bearing isolators further complement Parker’ssolutions program by offering an answer for applicationswhere improving the mean time between failure (MTBF) iscritical. The ProTech family relies on true non-contactlabyrinth seal technology to provide 100% exclusion ofcontaminants and 100% retention of bearing lubrication forthe life of the bearing. Fourteen standard profiles are availableto allow for ease of retrofitting most equipment. Typical sizerange is for shaft diameters from 0.492" (12.5 mm) to 38"(965 mm). ProTech has also been independently tested toIEEE IP55, IP56, IP66 and IP69k.Quick Sleeve, Wear Sleeve and V-SealsQuick Sleeves, Wear Sleeves and V-Seals areauxiliary components that provide additional convenienceto the Parker Sealing Solutions Program. Quick Sleeve shaftrepair sleeves and Wear Sleeves are economical,convenient solutions to create proper shaft surfaces.V-Seals can be added as a slinger type seal to protect theprimary seal or used as a primary seal to exclude dirt ingrease applications.03/28/061-2 Parker Hannifin CorporationEPS DivisionToll Free: (800) 233-3900www.parkerseals.com
