Description
R-152a (HFC-152a) Refrigerant Gas — 1,1-Difluoroethane
Low-GWP, zero-ODP refrigerant and propellant used in select refrigeration systems, blends, foam blowing, and aerosol applications.
Why choose R-152a?
- Lower climate impact: ~124 GWP (100-yr) with zero ozone depletion potential.
- Efficient performance: Good thermodynamic efficiency and fast pull-down in systems designed for A2 refrigerants.
- Versatile uses: Common in HFC blends, select low/medium-temp refrigeration, foam blowing, and as an aerosol propellant.
- High purity: Meets industry specifications for moisture, acidity, and non-condensables for reliable operation.
Applications & compatibility
- Applications: Blending component, stand-alone refrigerant in properly engineered A2 systems, foam blowing agent, aerosol propellant.
- Lubricants: Typically compatible with POE (polyolester) oils; verify OEM guidance for your compressor.
- Materials: Check elastomer and seal compatibility; follow equipment manufacturer recommendations.
What’s included
- Sealed cylinder/can with safety cap (size per variant).
- Valve: standard service fitting per size/region (see variant notes or contact us).
- Batch lot & traceability; Certificate of Analysis available on request.

FAQ
Is R-152a a “drop-in” for R-134a?
No. R-152a is flammable (A2) and should only be used in systems specifically engineered/approved for A2 refrigerants or in qualified blends per OEM/engineering guidance.
Which oil should I use?
POE oils are commonly used with HFCs including R-152a. Always follow compressor and system manufacturer recommendations.
What valve/fitting does the cylinder use?
Fitting type varies by package size and region. Check the variant notes or contact us for the exact service connection.
