DESCRIPTION

The UH-Q style polypack is manufactured by SKF/Polyseal and is pre-loaded with a Nitrile quad-ring giving positive lip contact at low pressure and vacuum conditions. This seal provides positive lip sealing at all pressures, longer life of the seal due to Nitrile’s lower compression set compared to urethane, and stability to the lips resisting collapse under severe load changes and high cycle rates.

The shell is molded in Lubrithane, ensuring flexibility for installation and high/low pressure performance.

The UH-Q seals are available in 4 styles: Standard (straight lip – the height and cross-section are the same) Standard B-Lip (beveled lip – the height and cross-section are the same) Deep (straight lip – the height is greater than the cross-section) Deep B-Lip (beveled lip – the height is greater than the cross-section)

Most sizes are available with either a straight lip or beveled lip. Beveled lip is denoted with a B at the end of the part number. See Part Number Definition below.
