4-1/4" ID X 5-1/4" OD X 3/4" HT

L50004250750B is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 4-1/4 in inside diameter, a 5-1/4 in outside diameter, and a height of 3/4 in. In service, this loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. Source specification: Loaded Lip Seal (type B) Urethane.

It resists abrasion and wear, ozone, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. Applications involving ketones or prolonged humidity at elevated temperature call for a different compound.

Typical settings include mining and heavy equipment, press and forming equipment, and hydraulic cylinders.
