3-1/2" ID X 3-3/4" OD X 1/4" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) supplied with a 3-1/2 inch inside diameter, a 3-3/4 inch outside diameter, and a height of 1/4 inch, catalogued under part number L12503500250. It combines a preloaded lip with pressure activation for consistent dynamic sealing. Source specification: Loaded Lip Seal (deep) Urethane.

The compound resists ozone, abrasion and wear, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Applications involving hot water and steam or prolonged humidity at elevated temperature call for a different compound.

Typical settings include off-highway equipment, high-pressure fluid power, and press and forming equipment.

Order part number L12503500250, sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
