*3-1/2" ID X 3-7/8" OD X 3/16" HT

APG stocks the L18703500, a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal measuring a 3-1/2 inch inside diameter, a 3-7/8 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. Supplementary detail from the product record: Loaded Lip Seal (standard) Urethane.

The compound resists extrusion under high pressure, impact and shock loading, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for exceptional abrasion resistance, very high tensile strength and load capacity. Exposure to ketones or acids and bases will shorten service life.

Typical settings include press and forming equipment, high-pressure fluid power, and hydraulic cylinders.

This item is sold individually under part number L18703500. Application requirements vary, so validate compatibility with your process conditions prior to installation.
