they use 150% of the tanks rated pressure so for a 4500psi tank they test it at around 6700psi
Some gas cylinders require regular testing because the pressure cycling they undergo in service could cause the propagation of even tiny cracks. This applies particularly to diving tanks, and to CNG tanks.
For the do it yourselfer, the 12 oz refrigerant cans are help upright and attached to the low pressure port.
Is r-22 Freon compatible with r-134a freon?
Contains no Freon. Freon was banned beginning in 1996.

Freon is DuPont's trade name. There are 2 types of Freon, Freon-11 is trichlorofluoromethane, while Freon-12 is dichlorodifluoromethane. All types of Freon have been banned from production since 1996. Refrigerants are manmade compounds not Elements
NO
When the fridge is not cooling due to freon leak or freon restriction.
Home freon and R-12 freon for vehicles (yes) but not R134a freon which you can get at any autozone..................

There is many different types of Freon. If the freon that you are trying to use is R-22 then you have to have a EPA certification to handle that freon. This freon is considered ozone depleteing. Now there is freon out there that is not ozone depleting like the freon in cars made after 1993. That is called R-134a which is sold everywhere even in Wal-Mart.
