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

APG stocks the L43704750750B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 4-3/4 inch inside diameter, a 5-5/8 inch outside diameter, and a height of 3/4 inch. A loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Additional detail on this item: Loaded Lip Seal (type B) Urethane.

Expect good resistance to ozone, abrasion and wear, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. Applications involving prolonged humidity at elevated temperature or hot water and steam call for a different compound.

Typical settings include mining and heavy equipment, construction machinery, and high-pressure fluid power.
