This is a genuine replacement inhalation gasket for use with half-face and full-face reusable respirators in the 3M 6000 series (and compatible models). The gasket helps maintain the inhalation seal by creating a tight interface between the the facepiece and the filter or cartridge assembly.
As an OEM replacement, this gasket ensures proper functionality of the inhalation pathway and helps maintain the overall safety performance of the unit.
Because it's packaged as a 20-pack, you will have plenty of spare parts to maintain several of your respirators.
