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

Part number L18703625 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 3-5/8 inch inside diameter, a 4 inch outside diameter, and a height of 3/16 inch. A loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. Additional detail on this item: Loaded Lip Seal (standard) Urethane.

The compound resists ozone, abrasion and wear, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. It is not the right choice where hot water and steam or prolonged humidity at elevated temperature are present.

You will find this material specified across off-highway equipment, high-pressure fluid power, and hydraulic cylinders.
