Tire Valve Caps

Car tire caps

Caps on tires absorb road unevenness very well, reducing the load on the throttle-free parts of the car's suspension. Thanks to the tires, a good grip on the road is ensured. And the main component of a fully assembled wheel is the tire cap.

General information

Caps for tires are check valves that force air into the tire. In addition, they do not allow the tires to release sufficient pressure. The valve includes a body, spool, and cap. These components have their characteristics. To choose a cap tire, you need to consider that it is subject to heavy loads, so when making a choice, remember about safety. Caps are used in tubes without tubes because tube tires have a built-in, inseparable cap.

Valve design for a car wheel

The tires cap can be made of rubber, collapsible, and hidden. The most common are rubber caps installed on a stamping or a cast disc. They can withstand pressure up to 4 atmospheres and are unafraid of temperature changes. Caps tires are available in different lengths.

The collapsible cap for tire includes several elements, including gaskets. They are made of metal and plated with chrome. They are not afraid of the effects of reagents, temperature changes, and exposure to water. Since these tire caps are metal, they can withstand high pressure.

The hidden tire cap is also made of metal and is similar to the collapsible one. The only difference is that there is no inflation bar. The spool is located in the middle of the element that attaches the cap to the wheel rim. These tires caps are used in high-speed cars and are best installed on alloy wheels.

Spool

The tires valve caps have a spool, which is a locking element. Thanks to it, pieces with different pressures are connected, but at the same time, air does not pass from one part to another. Tire valve tire caps can have one of three types of spool:

●     for tires with tubes;

●     traditional (for tires without a tube);

●     reinforced – for sports cars (up to 7 atm).

The spool works due to the movement of the movable component relative to the main element. It allows the valve cap tire to allow air to flow into the middle of the tire when inflated. But it does not release the air back at the end of pumping. If you press the valve slightly, you can remove a little perspective, lowering the pressure in the tire to the optimum (when it is overinflated).

Valve cap

It is mistakenly considered a decoration, but it is not. Thanks to it, the nipple is protected from dust and dirt. It ensures a longer service life. Therefore, when choosing tire valve caps, you must pay attention to how tightly and securely they are screwed onto the bar. There are plastic and metal tire valve cap.

In what cases will it be necessary to replace the valve?

A car tire can be used for 4-5 seasons, but valve caps tire will have to be changed much more often – for safety reasons, at least twice a year. The nipple has weak points: the rubber body, which cracks in the cold or when it dries out, and the spool, which is often damaged during use. Tire valves caps play an important role, so it is recommended to choose them carefully. Correctly selected tire caps increase safety while driving.
