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

Ordered as L31203750, this is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 3-3/4 inch inside diameter, a 4-3/8 inch outside diameter, and a height of 5/16 inch. The 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 exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. Expect good resistance to extrusion under high pressure, petroleum oils, and abrasion and wear. Exposure to acids and bases or prolonged humidity at elevated temperature will shorten service life.

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