Subject: Helmet Updates

Products Affected: Miller 400 Helmets

Miller diving helmets manufactured after October 1, 2002 will reflect the following updates.

1. All Miller 400 helmets produced after Oct. 1, 2002 will be serial numbered. This number can be found stamped into the helmet shell on the side block mounting area, behind the side block (see picture).

Miller Diving has a procedure for issuing serial numbers to Miller Helmets manufactured before October 1, 2002. This procedure is for owners of Miller Helmets who want to be able to easily identify their helmets.

2. All Miller 400 helmets will be equipped with a new Miller Emergency valve assembly, Part # 905-348.

3. All Miller 400 helmets will ship with a stainless steel nose block device, Part # 545-015, and new knob, # 550-249 which replace the older brass versions. This Nose Block Device requires the Nose Block Device Knob due to the threads on the ends of the two shafts being different. The original Miller Nose Block Knob (P/N 400-79) cannot be used with the new, P/N 545-015 Nose Block Device.

The new emergency valve and nose block device & knob will retrofit to all previous Miller 400 helmets.
