The Parker V-Seal is an all rubber rotary shaft seal that is used primarily for the exclusion of dirt, dust or water as well as retention of grease and other viscous fluids. The V-Seal can also be used as a secondary seal to protect primary seals from hostile environments. Centrifugal force produces a decrease in contact pressure of the lip as speed increases, keeping frictional losses and heat to a minimum.

Applications
V-Seals can be found in a variety of applications including appliances, automotive, agriculture, electric motors, rolling mills, gear boxes, pumps, conveyors, backup rolls, work rolls, pillow blocks, mining equipment, spindles

  • V-Seal A

    Most common style. Cross-section varies with shaft diameter.

    Operating Temperature Range
    NBR: -40 to +225 F (-40 to 107 C)
    FKM: -30 to +325 F (-34 to 163 C)

    Shaft Surface Speed
    Up to 1600 fpm (8.1 m/s)

    Choosing a Seal
    Select the larger V-Seal when the shaft diameter is on the boundary between two sizes.

  • V-Seal S

    Wide and tapered cross-section provides firm hold on shaft for higher speed.

    Operating Temperature Range
    NBR: -40 to +225 F (-40 to 107 C)
    FKM: -30 to +325 F (-34 to 163 C)

    Shaft Surface Speed
    Up to 1600 fpm (8.1 m/s)

    Maximum Pressure
    n/a

    Choosing a Seal
    Select the larger V-Seal when the shaft diameter is on the boundary between two sizes.

  • V-Seal L

    Narrow cross-section profile throughout the size range. Often used in combination with LER rings.

    Operating Temperature Range
    NBR: -40 to +225 F (-40 to 107 C)
    FKM: -30 to +325 F (-34 to 163 C)

    Shaft Surface Speed
    Up to 1600 fpm (8.1 m/s)

    Maximum Pressure
    n/a

    Choosing a Seal
    Select the larger V-Seal when the shaft diameter is on the boundary between two sizes.

  • V-Seal E

    Larger cross-section. Accommodates 0.5" axial movement.

    Operating Temperature Range
    NBR: -40 to +225 F (-40 to 107 C)
    FKM: -30 to +325 F (-34 to 163 C)

    Shaft Surface Speed
    Up to 1600 fpm (8.1 m/s)

    Maximum Pressure
    n/a

    Choosing a Seal
    Select the larger V-Seal when the shaft diameter is on the boundary between two sizes.

  • DS Excluder

    Designed for internal deflection of heavy oil surges or external exclusion of dust or spray. The DS features the traditional Clipper nonmetallic composite construction for enhanced stability and optimal performance.

    Operating Temperature Range
    NBR: -20 to +250 F (-29 to 121 C)
    FKM: -40 to +400 F (-40 to 204 C)

    Shaft Surface Speed
    Up to 2500 fpm (12.7 m/s)

    Maximum Pressure
    n/a

  • SSW Excluder

    Similar to V-seals except they are press fit on shaft for heavy duty applications. Designed for applications for external washdowns or severe dusty environments. The seal rides against the face of the housing to keep contamination from the primary seal. The SSW design features the traditional Clipper nonmetallic composite construction for stability and optimal performance.

    Operating Temperature Range
    NBR: -20 to +250 F (-29 to 121 C)
    FKM: -40 to +400 F (-40 to 204 C)

    Shaft Surface Speed
    Thru 2500 fpm (12.7 m/s)

    Maximum Pressure
    n/a
