The completeness ofParkersproductline allows us toprovide theoptimal designfor any rotatingapplication.
Parkers Rotary Sealing Solutions Program providesthe most complete coverage in the industry of shaft seals forrotating applications, for both OEM and MRO requirements.The completeness of the product line allows Parker to providethe optimal design for any given application. Parker is morethan just product. A complete solutions package has beencreated by supplementing the broadest range of productswith full engineering support, strict quality standards, directfactory field support, R&D and premier customer service. AtParker EPS, seals are not an add-on to our business, seals areour only business.
Clipper Oil Seal
The Clipper Oil Seal is the anchor of the rotary sealproduct line. The Clipper design features an integrally moldedrubber fiber outer case and an elastomeric seal lip. Theunique, nonmetallic construction will not rust or corrode andforms a gasket-type seal between the equipment housing andthe seal outside diameter (OD). With a wide range of profilesand material options, Clipper seals are available for shaftdiameters from 0.250" (6.35 mm) to over 65" (1651 mm).
Clipper Split Seals are known worldwide for being theeasiest split seal to install because they do not require acoverplate to keep them in the housing. The robust, compositeOD provides the best retention of any split seal on themarket. Replacing failed seals in the field with Clipper SplitSeals saves on downtime and lost production expenses. Tomake replacement even easier, specify Clipper solid seals asthe OEM solid seal. When cutting a metallic seal is required for in-field replacement, there is the the possibility of metalshavings entering the bearing. The non-metallic design of theClipper seal eliminates this possibility.
Parker Oil Seal
Parker Oil Seals provide additional coverage and includethe common metal OD construction for inch requirements andrubber covered OD construction for metric requirements.Single lip and double lip profiles are available as well as over100 special profiles for applications with unique operatingconditions. The typical size range is for shaft diameters from0.200" (5 mm) to 10" (254 mm).

FlexiLip, 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 Isolators
ProTech bearing isolators further complement Parkerssolutions 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 of contaminants 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-Seals
Quick Sleeves, Wear Sleeves and are V-Sealsauxiliary 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.
