Change to Product Bulletin No. 2 of 2004 9 June.

Subject: New Silicone Regulator Exhaust Valve

Products Affected:
All Miller Diving® 400 Helmets manufactured after June, 2004

A new silicone Miller Diving® Regulator Exhaust Valve, PN 910-030 is now standard on all new Miller Diving® Helmets as of June 2004. The new valve is softer and more flexible similar to other current regulator designs with the correct Miller Diving® mounting stem. Depending on the type of diving that you are performing, the new silicone valve can be used in place of the 910-029 in the Regulator Assembly to lower the exhaust resistance. The original style rubber Miller Diving® Exhaust Valves (910-029) are still used in the Water Dump Valve Assembly.
