Abstract: A vibration isolator grommet comprises a sleeve and an annular elastomeric element. The sleeve has a cylindrical portion with a radially outwardly extending flange at one end thereof. The elastomeric element has a flange underlying the flange on the sleeve, a cylindrical portion telescoped over the cylindrical portion of the sleeve, and a radially inwardly extending portion initially underlying the cylindrical portion of the sleeve but movable radially outwardly upon axial advancement of the sleeve relative to the elastomeric element to lock the grommet in a workpiece.

Abstract: A rod wiper for disposition about the rod of a fluid actuator comprises an annular wiper element of relatively high durometer having a pair of axially spaced lips engageable with the rod of the actuator, and an annular elastomeric element of relatively lower durometer disposed radially outwardly of said wiper element. The elastomeric element is normally engaged with only the wiper element and with an axial wall of a rod housing. However, the elastomeric element is movable into engagement with a radial wall of the rod housing in the presence of dirt and scale on the rod. The axial force on the elastomeric element results in an increased bias of the lips of the wiper element on the rod.

Abstract: A valve stem oil seal comprises a cup-shaped case engageable with the valve guide of a piston-type internal combustion engine in sealing relationship. A seal element has a radial flange portion disposed between a radial flange on the case and a support washer so as to be radially movable relative thereto and an annular portion sealably engaged with the valve stem.

Abstract: A valve stem oil shield comprises a cup-shaped deflector having a radial flange with an aperture therein for the acceptance of the valve stem. An annular grommet of U-shaped cross-section is disposed between the deflector and the valve stem to mechanically secure the oil shield to the valve stem. Leg portions of the grommet slidably engage the deflector thereby to effect a seal between the deflector and valve stem.
