Q: What's the difference between SGE 400/3 and SGE 400/3BB?Ā A: The SGE 400/3 has aĀ siliconeĀ face seal. The SGE 400/3BB has aĀ butyl rubberĀ face seal, which provides superior resistance to chemical warfare agents (nerve agents, mustard gas) and meets stricter CBRN requirements. The 400/3BB is also slightly lighter. If you need maximum chemical protection, consider the 400/3BB version in our NBC Protective Kit.
Q: Why is butyl rubber better than silicone?A: Butyl rubber is impervious to nerve agents (sarin, VX), mustard gas, and other chemical warfare agents. Silicone provides good protection but doesn't meet the same military CBRN standards. Butyl rubber also has 200x better vapor resistance than natural rubber.
Q: What filters work with this mask?A: Any 40mm NATO threaded filter (EN148-1 / DIN 3183). We recommend our Multipurpose CBRN 40mm Filter ($54.95).
Q: Is this the same mask in the Tactical NBC Protective Kit?A: Yes. The Tactical NBC Protective Kit ($495.99) includes the SGE 400/3BB mask plus a filter, Tychem chemical suit, butyl gloves, overboots, and carry bag.
