Are all 134a cans self-sealing?
All new 2018 AC Avalanche products with R-134a refrigerant are equipped with EPA mandated self-sealing valves. As required by Section 608 of the EPA Clean Air Act, all refrigerant cans are required to have a self-sealing valve which remains closed when the recharge hose is removed.
What is a self-sealing refrigerant can?
The self-sealing can on the right replaces the foil with an internal Schrader-like valve which regulates flow dependent on the pressure applied by the dispensing tap. A unique benefit of the “self-sealing” can is that the dispensing tap can be completely removed from the can without venting the remaining. refrigerant.

Is AC Pro self sealing can?
The new can has the self-sealing mechanism that will prevent refrigerant from escaping.
What is self sealing valve?
The outlet points from which gases & vacuum are drawn are of self sealing type and have non-interchangable outlet fittings. To break the connection, the milled collar round the orifice is rotated a few degrees to the right, when the safety key plug is automatically elected and the gas flow is cut off.

What’s the difference between puncture and self sealing refrigerant cans?
For this reason, refrigerant cans manufactured in 2018 and later were redesigned to include a specialized valve which automatically reseals the can when the dispensing tools are removed. The aerial view of the cans (below) shows the major differences in cap appearance between the traditional “puncture” style cans and the new cans.
How is refrigerant released from a can?
As you screw the adapter onto the top of it, there is a small tube which is cut on a bevel which punctures the top of the can, which then releases the refrigerant from the can and then is available to flow after you press the lever. There is no check valve at the top, but a thin piece of metal which contains the R134a until punctured.
Are there restrictions on the size of refrigerant cans?
Section 608 therefore introduced several restrictions to the sale of refrigerants. Among these restrictions is the stipulation that small cans (less than two pounds) must be equipped with a “self-sealing” valve to prevent refrigerant from venting into the atmosphere.
