Valve stems and caps are widely used in almost every vehicle with tires. The main purpose of valve stems and caps are to transfer the air pressure and store it inside the tire. These small plastic and metal pieces are the reason there are millions of vehicles are driven on rubber tires, otherwise, people are still driving on wooden tires.
Sometimes, due to their size, they are not given as much importance however if there is something wrong with these parts of your car, your whole car will stop moving because they are directly related to the tire which moves the car essentially.
Valve stems comes in two different types, one is tubeless rubber stems and the other is metallic stems. The rubber one is widely used with passenger cars and heavy vehicles, however, the metallic one also uses with those cars that go faster like racing cars and also heavy-duty vehicles.
Inflate and deflate Air
The valve stems are the only source to inflate and deflate the tire until there is no hole in the tire. The air goes through the valve stem, by pressing the pin inside it, which opens the valve core to intake and lose the air, as you took out the gauge or inflator from the pin, the valve core closes which stops air from deflating.
Caps protect valve stems
The outer part of valve stems that stick out the wheels are made up of steel, and steels are very common to get rusty when in contact with water. Also, it can get debris and might get damaged by rocks. All of these things could happen unless there is a valve stem cap is covered on it. The stem caps are very important if you want to protect your tires from leaking air every time often.
Valve caps maintain the air pressure
When someone inflates the tire, the process is to fill the air through valve stems. However, if there is a fault in the stems or a small leak, the valve stem caps also reduce the rapid loss of air pressure. As caps are connected to the stems, the air hardly finds a place to escape and sit on the tire for longer. On the other hand, if there are no valve caps, they will lose air in case of a leak on valve stems.
Other benefits of Valve Steams And Caps
Improve Car looks
Other than protecting the valve stems, stem caps also improve the look of your car. Matching them with wheel locks can bring a different look out of your tires. There is a green color valve cap that you may see with other tires, the reason for that is there is nitrogen air inside those tires, that consider improving the fuel mileage without damaging the environment due to less emission.
Valve Stems With TPMS
If you are replacing the valve stems or its caps, and your car is not equipped with a tire pressure monitoring sensor, then instead of buying valve stems or caps, you should go with the stems and caps that come with the TPMS sensors.
There are two different TPMS available in the market, one that sits instead of the valve stem and the other one that is used as the valve stem caps. Both of them are efficient and show live air pressure results. So whatever you prefer, it is better to equip TPMS in your car due to the benefits it provides.
When and how to replace valve stems
If your tires are dropping air quickly, then this could be one of the reasons that your valve stems are damaged. There is no time limit in replacing the valve stems, as they usually come new with the new tires and work as long as the tires work. However, valve stems can get damaged within a few months of a new tire purchase as well.
Just check your valve stems casually, and if there is something wrong then replace them anytime. The process of changing the valve stem is quite simple for someone who knows how to dismount and mount a tire. For someone who doesn’t know the p[rocess of installing new tires, you should get the assistance of professionals to change the valve stems. Because if it doesn’t sit properly the air won’t stick inside the tire.
The valve stems and caps of valve stems may look small but do one of the biggest things is to move the car. Without them, the vehicle won’t move. That is why keep a close look at both of these things because in case there is a fault in any one of them, the impact of it will go directly toward the air pressure of the tire. To keep a well maintain air pressure in your tires, you have to protect them and repair them in case there is a fault in any of the things.
