We offer a wide range of aftermarket tyre valve caps and dust caps for Alfa Romeo cars. We have valve caps to suit all Alfa Romeo models, wheel styles and budgets. As well as adding aesthetic appeal to your wheels, the main purpose of a valve cap is to protect the tyre valve itself from dust, dirt and moisture ingress, as well as preventing tyre pressure from escaping. These valve caps are also often referred to as Alfa Romeo dust caps or Alfa Romeo valve stem caps.
