Bulb and Air-Flo Inflation Bulbs & Valves

When a sphygmomanometer stops holding pressure, the culprit is almost always a cracked bulb or a worn air-release valve — not the gauge itself. This collection covers the replacement inflation bulbs and valves that keep manual blood pressure equipment accurate and serviceable, so a single failed component doesn't send an otherwise good aneroid or mercury unit to the trash.

At the heart of the selection is the Air-Flo Blood Pressure Inflation Bulb & Valve (1890), built for use with all standard sphygmomanometers. It's made from natural rubber latex with stainless steel interior parts and a solid brass valve body — the combination clinicians look for when they want a bulb that grips comfortably, inflates the cuff smoothly, and releases air at a controllable, steady rate for accurate readings. The metal internals resist the pitting and sticking that cause cheaper valves to leak or dump pressure too fast.

Buyers here typically fall into two groups: facilities standardizing on a reliable replacement part across many units, and practitioners repairing a favorite hand unit. A few things worth checking before ordering — confirm your cuff tubing diameter matches the bulb's connector, and note that this bulb contains natural rubber latex, which matters in latex-sensitive environments. The air-release valve is the part that most affects reading precision, so a quality brass valve is a worthwhile upgrade over the original if yours has become jerky or leaky.

Because these parts are universal-fit, they're an inexpensive way to extend the life of equipment you already trust rather than replacing the whole instrument.
