3M 7582 Inhalation Valve (Replacement Part for 7500 Series Respirators)

The 3M 7582 inhalation valve is a genuine replacement part for the 3M 7500 Series reusable half-face respirators. It maintains a clean, one-way flow of filtered air into the mask, so keeping it in good condition is essential for the respirator to seal and perform as designed.

Product overview

The 7582 is the inhalation valve that sits behind each cartridge port on the 7500-series facepiece. Because valves can wear, crack or collect debris over time, replacing them as part of routine maintenance keeps the respirator working correctly. Fitting a genuine 3M valve ensures the airflow direction and seal match the original design.
