4-3/4" ID X 5-3/8" OD X 5/16" HT

Ordered as L31204750, this is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4-3/4 in inside diameter, a 5-3/8 in outside diameter, and a height of 5/16 in. The loaded lip seal maintains contact with the sealing surface even as clearances change under load. Source specification: Loaded Lip Seal (standard) Urethane.

The compound resists petroleum oils, extrusion under high pressure, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers very high tensile strength and load capacity, exceptional abrasion resistance. It is not the right choice where hot water and steam or ketones are present.

Maintenance and OEM teams specify it across mining and heavy equipment, high-pressure fluid power, and press and forming equipment.

Reference part number L31204750 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
