Non-pressurized Dust Caps for bottles and pumps


contamination is an air guns worst night mare. the slightest bit of debris can cause a leak or damage to the firing valve. it is nearly impossible to keep dust out of the foster fitting especially in the field, so i have  a solution for this potential problem on my bottle and thought others might be interested in one for them selves.these are great for hand pumps as well because the fitting is so close to the ground. the cap basically plugs the hole and securely snaps in place so that debris can not work its way into the air hose.
