Package Included 4 pcs tire valve caps Practical Use Scenarios Daily driver maintenance: worn or missing plastic caps on a commuter car to prevent dirt buildup and help maintain consistent tire pressure. Off road or work vehicles: Install on trucks or pickups to protect valve stems from mud and debris encountered during off road or jobsite use. Bicycles and motorcycles: Use on bikes and motorcycles to avoid air loss and keep valve cores clean during storage or frequent rides. Installation and Care Notes Before installing, apply a small amount of grease lubricant to the threading of the valve stem to reduce the risk of the metal cap fusing to the stem. If valve caps are exposed to acidic or alkaline liquids for extended periods, they may become difficult to remove. Loosen the caps at least once per month in such conditions to prevent seizing. Tighten by hand; avoid overtightening to prevent damage to the valve stem or cap.
