Abstract

A visual tire pressure indicator having a hollow outer body, an inner cap fitted within the outer body and an inner body secured to the inner cap and generally co-axial with the outer body. A pair of indicator sleeves is slidably disposed around the inner body. A pre-calibrated spring helically surrounds the inner body for biasing or urging the pair of indicator sleeves towards the inner cap. A valve core body is threadably engaged to top threads of the inner body while simultaneously being fitted snugly against an inner wall of the inner body. The valve core body has a longitudinal bore wherethrough air is passed to be emitted into a tire. A control rod has a valve core cap secured thereto and is slidably disposed in the longitudinal bore such that when it is depressed, air can be passed through the longitudinal bore. A valve core spring is positioned around the control rod and in the longitudinal bore to bias the control rod such that the core cap can seal-off the longitudinal bore.
