DUAL TIRE PRESSURE EQUALIZER AND INDICATOR ABSTRACT A spring biased cup 44 urges a flexible diaphragm 40 against a seat 30 between pressure fittings 20,22 of two adjacent vehicle tires. A slotted (58) arm 52 upstanding from the periphery of the cup engages an offset pin 74 of a rotary, color coded pressure indicator disc 62,62a. When a sufficient inflation pressure is applied the diaphragm is forced off the seat to equalize the tire pressures, and the correspondingly moved cup arm rotates the disc to display the pressure level through viewing segment windows 70. If one tire blows out the diaphragm seats to isolate and maintain pressure in the other tire, and the disc is simultaneously rotated to display a red hazard color.
