3M M-354 Forehead Seal

The 3M M-354 Forehead Seal is a replacement component designed for M-300 series welding helmets. It provides a secure interface between the helmet shell and the wearer's forehead to maintain comfort and protection during use. This new part is supplied in black and integrates directly with the specified helmet range.

Suits M-300 helmet owners needing a replacement seal

This seal suits welders and fabricators who own a compatible M-300 helmet and require a new forehead interface to restore fit and hygiene. It is not for users of other helmet brands or models lacking the M-300 mounting configuration. Buyers needing additional protective gear such as respirators or alternative headgear assemblies should look elsewhere.

Questions about this item

How can I confirm the forehead seal is working correctly with my M-300 helmet?

When installed on the M-300 helmet, the seal should sit flush against the forehead without gaps and remain secure during head movement, maintaining a consistent barrier.

What is included in the box and do I need to purchase the helmet separately?

The box contains the M-354 forehead seal only. The M-300 helmet is not included and must be purchased separately for the seal to function.
