R134a vs R1234yf (Automotive)
| Feature | R134a | R1234yf |
|---|---|---|
| Vehicles | Pre-2017 (mostly) | 2017+ (EU/UK) |
| GWP | 1,430 | 4 |
| Fittings | 14mm / 13mm | 12mm M |
| Flammability | Non-flammable (A1) | Mildly flammable (A2L) |
| Cost | Moderate | High |
| Cross-compatibility | No | No |
Important Notes
- Not compatible with R1234yf: Different fittings prevent cross-contamination
- Recovery required: R134a must be recovered, not vented to atmosphere
- Dedicated equipment: Use R134a-specific recovery machines
- Ongoing demand: Millions of R134a vehicles still require service
