its an angel air bottle. im pretty sure its 3 years but am just making sure.the date on it is 03-01. this will be the first test that it will need from manufacture.
thanks
general rule of thumb, if it's older than 2003, the first test point is 3 years after the born date. If it's 2003 or younger than it's more than likely to be 5 years before first test. That's on fw2 bottles.
