Seller: blackjacktech (292) 100%, Location: Aberdeen, North Carolina, Ships to: Free Local Pickup, Item: 182695336007 16 5000 PSI DOT cylinders available. These are cascade bottles that are very heavy duty (not the lightweight bottles that are widely available). These cylinders have been used for a scuba cascade system and currently contain oxygen compatible air or nitrox. The bottles have CGA347 fittings and are just out of hydro (hydro date is 3/12). The bottles could be used for any high pressure air system such as a paintball, scuba, or SCBA system. One bottle is devalved and needs to be tumbled to remove rust. We will not ship these bottles because of the weight (approx. 350lbs each). Price is $375 firm PER BOTTLE. Buy 8 or more and we'll throw in the bottle that needs to be tumbled for free. Condition: Used, Condition: Very good condition. Hydro went out in March of this year.
