• Nitrile (NBR) lip material — 60–80 durometer rating; resistant to oil, grease, and common automotive fluids
• Reinforced outer case — helps prevent installation damage and enhances housing retention
• Ribbed rubber inner diameter — seals minor spindle imperfections and promotes positive spindle seating
