Dear Miller Customer,

As part of the reorganization and standardizing of the manufacturing process for the Miller 400 Diving Helmet, Miller Diving has converted all the old part numbers to new ones that conform to a system already in place. These new numbers will also reflect additional parts not previously available and upgrades to existing parts.

An updated exploded view of the Miller 400 Helmet as well as the face/weld shield reflecting these new numbers is now available. It is an Adobe Acrobat pdf file which requires the free Acrobat Reader to view it. Also online is the Miller 400 Maintenance Manual in PDF format. (this is a large file and will take a while to download)

A part number conversion chart showing the New Miller Part numbers and the old part numbers that they replace along with the current part name/description is available. The list is sorted by current exploded view location number. Parts that are new will not have a corresponding older miller number.

If you have any questions or comments, please feel free to contact Kate at 805.928-7772 x218.

Thank you

Sincerely,

The Miller Sales Dept.
