4-5/8" ID X 5-1/8" OD X 1/4" HT

APG stocks the L25004625, a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4-5/8 in inside diameter, a 5-1/8 in outside diameter, and a height of 1/4 in. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. This item is further identified as Loaded Lip Seal (standard) Urethane.

It resists petroleum oils, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. It should not be specified for service in ketones or prolonged humidity at elevated temperature.

Maintenance and OEM teams specify it across mining and heavy equipment, press and forming equipment, and off-highway equipment.

Order part number L25004625, 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.
