APG stocks the L37501312, a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal supplied with a 1-5/16 inch inside diameter, a 2-1/16 inch outside diameter, and a height of 3/8 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. The compound resists petroleum oils, ozone, and impact and shock loading. Applications involving acids and bases or ketones call for a different compound.

Maintenance and OEM teams specify it across construction machinery, hydraulic cylinders, and mining and heavy equipment.

L37501312 ships individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
