The Q-V (Quick View) valve consists of a permanent irremovable dust cap, a built-in tire pressure gauge (with numbers, lines and indicator) viewed through a transparent window located in the center of the valve.
Billy the inventor explains "most people know that upon checking the air pressure of their tires on their cars, trucks, campers, motor homes and especially transports or just about any vehicle on wheels can be indeed a hassle. Typically a driver must bend to the ground, remove a dirty dust cap and apply an accessory pressure gauge to obtain a tire pressure reading. Many drivers go to service stations to check the pressure of their tires and often learn that the service station does not provide a pressure gauge or their air pump pressure gauge may be temporarily out of service".

Thus the invention of the Q-V tire valve came into play.

The revolutionary Q-V valve allows a driver to obtain a pressure reading of their tires in seconds. A driver needs only to slightly bend over and with a quick glance obtain a tire pressure reading as the new Q-V valve incorporates a built in tire pressure gauge.

The Q-V valve is installed on the rim of the wheel like a standard tire valve, therefore it cannot be removed and is theft free. For more information and photos, type in google "Billy Cousineau"
