7/16" ID X 11/16" OD X 1/4" HT

APG stocks the L12500437250B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 7/16 in inside diameter, an 11/16 in outside diameter, and a height of 1/4 in. A loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Source specification: Loaded Lip Seal (type B) Urethane.

Expect good resistance to impact and shock loading, abrasion and wear, and extrusion under high pressure. Polyurethane (AU/EU) is known for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. Applications involving acids and bases or prolonged humidity at elevated temperature call for a different compound.

You will find this material specified across mining and heavy equipment, high-pressure fluid power, and press and forming equipment.

Stocked as L12500437250B and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
