R507 Refrigerant — 25 lb Cylinder, 100% Virgin Factory Sealed
R507 (R125 / R143a azeotropic blend) is the high-efficiency answer for low temperature commercial refrigeration. Compared to R404A, it delivers slightly higher capacity with lower compressor discharge temperatures — which is why many supermarket racks, walk-in freezers, and ice machines specify it. As an azeotrope, it behaves like a single refrigerant: no glide, no fractionation, predictable top-offs.
What's in the jug: 25 lbs of virgin R507, factory sealed for guaranteed purity. POE oil systems.
Common applications:
- Supermarket low-temp racks and display freezers
- Walk-in freezers and reach-in freezers
- Ice machines and commercial food service
- Industrial process cooling and cold storage
R507 vs R404A: The two are close cousins and often interchangeable in low-temp systems, but R507's azeotropic nature gives it an edge in flooded and low-temp applications — better efficiency, easier service. If your equipment nameplate calls for R507, this is the jug.
Good to know: Like R404A, R507 has a high GWP (~3,985) and falls under the AIM Act phasedown, so long-term supply will tighten. Stocking at today's wholesale price is the smart move.
California and New York orders: reclaimed R507 only, per state regulations. Purchase requires EPA Section 608 certification. EPA requirements.
