The 3M 7000029584 is a replacement full face plug designed to seal DIN ports on compatible 3M full facepiece respirators. This small but critical component maintains the integrity of unused DIN port openings, preventing contamination ingress and ensuring a proper face seal during use. Licensed respiratory protection technicians and safety equipment service personnel install this part during routine maintenance or when replacing damaged port covers on full facepiece assemblies.
This plug is intended for use with 3M full facepiece respirator models that feature DIN-style ports. It is a direct OEM replacement component suited to industrial hygiene programs, confined space entry setups, and other environments where full facepiece respiratory protection is required. The plug keeps unused ports sealed when cartridges or other accessories are not connected to those positions.
Designed as a replacement part for 3M Full Facepieces 6000DIN and 7800S series. Use to seal DIN ports on these facepiece models.
Installation should be performed by a qualified respiratory protection technician or trained safety equipment personnel. Before servicing any respirator component, remove the facepiece from service and inspect all sealing surfaces for damage. Ensure the DIN port and plug are free of debris before seating the plug. Follow applicable OSHA respiratory protection program requirements and the manufacturer service instructions when performing maintenance on full facepiece respirators.
