The World Leader in Ammunition Sealant Technology!

Ammunition is not traditionally sealed against water and the ammunition casing is not sufficient protection in inclement weather or marine environments. Hernon Manufacturing has developed patented systems for sealing ammunition against water and other contaminants. Our sealants ensure reliable ammunition performance including improved ballistic precision and allow the user to move freely through and below water environments confident that their ammunition will not be compromised.
