DESCRIPTION

The UH-B-HT 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 a high-temperature 95A Lubrithane rated up to 250F, which ensures a useful balance of strength and flexibility. It is a premium grade material that has superior temperature and compression set resistance. It is not suitable for water above 150F.

The UH-T seals are available in 2 styles: Standard B-Lip (beveled lip – the height and cross-section are the same) Deep B-Lip (beveled lip – the height is greater than the cross-section)
