3M 7000052742 Speaking Diaphragm Assembly Respirator Part

Product Description

The 3M 7000052742 is a replacement speaking diaphragm assembly designed for use with 3M Ultimate FX Full Facepiece Reusable Respirators. The speaking diaphragm allows the wearer to communicate vocally while maintaining a sealed facepiece, a critical feature in industrial environments where verbal communication is required during respirator use. This assembly replaces a worn or damaged diaphragm and restores the voice-transmission function of the facepiece without requiring replacement of the full unit. Weighing 0.37 pounds, the assembly is a lightweight, direct-fit replacement component intended for installation by safety professionals or trained workers managing respiratory protection programs.

This speaking diaphragm assembly is compatible with 3M Ultimate FX Full Facepiece Reusable Respirators, specifically the FF-401, FF-402, and FF-403 models. It is suited for use in industrial, commercial, and hazardous-environment applications where full facepiece respiratory protection is required and verbal communication between workers must be maintained. Safety coordinators and industrial hygienists commonly specify this replacement part as part of a routine respirator maintenance program.
