The 3M Bayonet Cap 6880 is a replacement component used in 3M reusable full-face respirators or dual airline breathing tubes. The purpose of this part is to close off the bayonet attachment port so that air is directed through the proper airflow path.
It is made of black plastic and it is designed for complete compatibility with 3M full facepieces and combination dual airline breathing tubes. It serves as a system component within 3M’s respiratory protection gear, helping maintain correct airflow direction when the port is not in use.
