for all the trouble and issue to use an old tank..you can buy a brand new air compressor tank for a few hundred...believe me im cheap SOB..but when it comes to saftey issues, and this is one..I try not to cheap out where it could cost some missing flesh...
go ahead..its your life..ill stick with buying products made for a specific purpose rather than " trying to see" if something else will work.....hey on anything not life threatening im all for innovation...just know the risks....But you just showed how even a purpose built air compressor tank can explode.
Why would I buy one of those when a water heater is cheaper?
At one point a number of years ago I somehow ended up with no working compressor or air tank which is kind of ridiculous given how many I've had over the years. So for a while I just used a spare truck wheel as an air tank . Only needed it for refilling the kids bike tires so it was more than adequate. It was rated to 80psi.
A 12v compressor will not deliver enough air volume is what he says. I guess he wants a lot of nitrogen quick.
maybe your $19.99 cheap schit 12 volt vibrator..but if you crack that moth infested wallet of yours open, there are many high volume 12 volt compresors that will fill a truck tire pretty fast...That and all those 12v compressors are garbage and take forever. I keep at least one in every vehicle but I also have an air tank in the camo van. Just spin the valve off a propane tank and fill it with water. My buddy uses an old party helium can.
To drain any water that might build up just store it upside down and before you use it release some air.
They get hydrotested to like 200psi and the resting pressure of propane is around 120psi at 70f but can easily get to 150psi on a warm day so I have no qualms using one for air.
