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

L12504000 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 4 in inside diameter, a 4-1/4 in outside diameter, and a height of 1/8 in. In service, this loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. This item is further identified as Loaded Lip Seal (standard) Urethane.

Expect good resistance to abrasion and wear, extrusion under high pressure, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. Verify compatibility before use with hot water and steam or acids and bases.

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

Stocked as L12504000 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
