BEST valve caps and stems PART DEALS MINIMUM EFFORT!
valve caps and stems
The valve caps and stems for your vehicle's tyres play an important role as they help prevent various materials and debris getting into the tyre. Here we will explain more.
Buying valve caps and stems
When it comes to buying valve caps and stems they are generally a universal fitting, so you don't need your tyres´ dimensions or any other information to buy them. Most of the caps available will be black, though they are available in different colours and different materials. While they are small parts, the tyre valve cap has an important role in helping to prevent debris and other materials thrown up by the road from entering the stem and the tyre - hence they are usually referred to as dust caps.
The valve stem is a valve that is designed for allowing air to enter the tyre and then close automatically and remain sealed so that the tyre's pressure remains constant. It does this by using a spring to help prevent the air from escaping - and hence why we need caps to protect this function from corrosion and debris affecting it. Again, there are different types of valve stems available but generally for car tyres there's just one universal type that you will be needing.
Valve caps can vary in colour
As mentioned earlier, valve caps can vary in colour and regular tyres will be needing a black cap on the valve stem and sometimes the manufacturer will use a silver cap because it may suit the alloy wheels and both the black and silver cap indicates that the tyre contains air. If you see a tyre with a blue or green cap located on the valve stem, this will indicate that the tyre contains nitrogen. Obviously, not many drivers will be filling their tyres with nitrogen for every day driving. Nitrogen as a tyre filler tends to be used by those in motor racing since nitrogen can retain its pressure more easily over the long-term, than air will. The gas also deals more easily with temperature swings which could be crucial in motor racing. Also, dust caps are available in plastic designs and these are cheap to buy, while metal does caps for a valve stem will cost several times more but may suit the wheel's design.
Top end of vehicles may offer branded tyre valve caps that will be manufactured to a high standard and, in some instances, be chrome plated. The cap will probably carry the vehicle manufacturer's marque to help set this type of cap aside from others. For those who are modifying their vehicles, this type of branded valve cap may be of interest to add something of note to their project.
