134a Refrigerant Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

CANIPHA is the best-performing 134a refrigerant brand in July 2026, moving 5,000 units across 1 ASIN for 19.2% of Top 10 volume. ZeroR follows with 5,000 units (19.2%), ahead of A/C Pro on 4,000 units (15.4%).

Volume is spread across 9 brands, with the top three holding 53.8% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $20.93 to $43.49, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B07RMSL8SK booked 4K units at $20.93, with ▲ 700.0% MoM change. On the growth side, B0D8NTS4PM leads positive momentum with ▲ 300.0% MoM growth on 400 units, with B0FQ7S2FVR close behind at ▲ 300.0% MoM on 400 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
