Air Conditioning Car Engine R134aNational R456A is a new lower GWP (global warming potential) alternative to R134a in automotive aftermarket.

National R456A has almost the same capacity and efficiency vs R134a while having only half the GWP.

With over a 30% quota reduction (vs 2023) from January 1st 2024 - R134a will have reduced availability and become much more expensive.

National R456A could be the solution to this problem.

With a GWP of 626 vs 1,430 (R134a) manufacturer's can make more than twice the amount of refrigerant using the same quota. Fully compatible with existing R134a systems and equipment with no seal replacement or oil change required.
