APG stocks the L37504500625, a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal built to a 4-1/2 in inside diameter, a 5-1/4 in outside diameter, and a height of 5/8 in. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Supplementary detail from the product record: Loaded Lip Seal (deep) Urethane.

Expect good resistance to petroleum oils, ozone, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. It should not be specified for service in prolonged humidity at elevated temperature or ketones.

Maintenance and OEM teams specify it across press and forming equipment, off-highway equipment, and hydraulic cylinders.
