The Air Bleeder Valve Stem is a crucial component for the Gilson Concrete Air Meter, designed to precisely control air pressure within the meter's chamber. This stem meticulously screws into the pressure chamber cap, facilitating the safe and controlled release of air pressure during operation. For optimal performance and to ensure an airtight seal, it is essential to use this valve stem in conjunction with the Bleeder Valve Cap and the Gilson Gasket. This combination helps maintain the accuracy and longevity of your concrete air meter.
