Compatibility: Dust Caps for Car Tyres for Bentley Continental GT II 2011-2015 Material: Made from high-quality thickened alloy material plus PA composite material. Strong, not easily deformed under pressure, and designed to protect the valve from damage, rust, and corrosion while helping prevent tire air leakage and extending valve stem life. Easy installation: Simple screw-on design. The dust cap threads onto the tire valve stem by hand, and the steel valve caps are easy to thread onto the valve stem when you want to check air pressure. Protection and performance: Includes a rubber O-ring inside the tyre dust caps to delay air leakage if the valve leaks. The caps keep dust and water out to prevent valve stem corrosion and maintain valve integrity. Use scenarios: - Routine tire maintenance and air pressure checks at home or in a service shop. - Driving in wet or dusty conditions where valve exposure is higher. - Long trips or periods of vehicle storage where valve protection helps extend life.
