Air Alert Valve Cap - Set of 4
The air alert valve cap is easy to install since the valve cap is self-calibrating no further calibration needs
to be done by the installer.
The Valve Cap is also 100% self-contained with onboard batteries. All four LED Tire Alert Valve Caps can be
installed in just a few seconds more than it takes to check the tire pressure and it does not need the assistance
of a trained technician.
The AIR ALERT Valve Cap is a small and simple device that will start blinking if the tire pressure falls about 4
psi below the correct pressure. It is an active warning, which will be seen by the driver as she/he approaches the
The AIR ALERT Valve Cap is designed to replace the regular dust cap on a pneumatic (air filled) tire. Therefore
it will fit most passenger cars, pick up trucks, large trucks, tractor trailers, fork lifts, motorcycles, bicycles,
lawn mowers or wheel barrels. The AIR ALERT Valve Cap is small (approx. 1" x ½ ”) and light (only 0.3 oz which
is lighter than a standard letter) that it will have virtually no impact on the wheel balancing for on the
appearance of the vehicle.

- The handling of the car.
- The fuel consumption.
- The life of the tires.
The AIR ALERT Valve Cap is small approximately 1" x ½ ” (24 mm x 13.5 mm). The weight is only 0.35

and the clear cap is made of clear Polycarbonate. It has no moving parts except a sensor, which will react if the
tire pressure drops. The AIR ALERT Valve Cap is entirely sealed and therefore no moisture, dust or dirt can enter
The AIR ALERT Valve Cap is self-calibrating. When the cap is mounted on the valve stem the first time, it will
memorize that tire pressure. The cap is calibrated for life and does not need to, and cannot be, updated later. The
AIR ALERT Valve Cap can be calibrated to any tire pressure between 10 and 130 psi. Therefore, it is not necessary
for the retailer to carry a large inventory of different caps since one size fits all.
Easy to install
Since the AIR ALERT Valve Cap is self-calibrating no calibration needs to be done by a professional installer.
The AlR ALERT Valve Cap is also 100% self-contained with onboard batteries. All four AIR ALERT Valve Caps can be
installed in just a few seconds more than it takes to check the tire pressure and it does not need to be done by a
trained technician. Compared to the in cabin displays the AIR ALERT Valve Cap does not have the potential
interference with some electrical devices in the vehicle like the engine-, ABS- and driving-computers. No holes
have to be drilled or any other intrusions to the car that could potentially void the warranty.
Easy to use
The AIR ALERT Valve Cap is designed to be easy to use and does not require any special tools, skills or knowledge to either install or monitor.
It will blink when tire pressure approx. 4 psi (0.3 bar) below the set original pressure. It can be checked
for functionality and battery condition by simply unscrewing the cap. If it is in working condition, it will
immediately start blinking.
The blinking light will catch your attention as you approach the vehicle, before you are distracted with all
other elements of driving.
The life span of the AIR ALERT Valve Cap basically depends on of the battery shelf life. After 2 to 3 years of
standby time, the AIR ALERT Valve Cap can still blink about up to 3 weeks. We recommend that the AIR ALERT Valve
Cap will always be changed simultaneously with the valve stem when replacing the tires or at least every other
The AIR ALERT Valve Cap is made of lightweight materials and will therefore have extremely little impact on the
