APG stocks the L18703500375B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 3-1/2 inch inside diameter, a 3-7/8 inch outside diameter, and a height of 3/8 inch. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. This item is further identified as Loaded Lip Seal (type B) Urethane.
As a material, Polyurethane (AU/EU) is known for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. The compound resists extrusion under high pressure, abrasion and wear, and impact and shock loading. It is not the right choice where prolonged humidity at elevated temperature or hot water and steam are present.
It sees regular use in hydraulic cylinders, mining and heavy equipment, and off-highway equipment.
Stocked as L18703500375B and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
