3M 7000002035 Full Facepiece Head Harness

Product Description

The 3M 7000002035 is a replacement head harness assembly designed for use with 3M full facepiece respirators. The harness secures the facepiece firmly against the face to maintain a proper seal during use, making it a critical component for respiratory protection in industrial, chemical, and hazardous-environment applications. Weighing just 0.3 pounds, this lightweight assembly is straightforward to swap out in the field. It is typically installed by safety-equipment technicians, industrial hygienists, or trained end users performing routine respirator maintenance.

This head harness is intended as a direct replacement component for the 3M Full Facepiece series. It is suited for use in environments where full-face respiratory protection is required, including industrial facilities, painting operations, chemical handling, and confined-space entry. Proper harness condition is essential to maintaining facepiece fit and protection factor, making timely replacement part of a sound respirator maintenance program.
