Upgrade your John Deere tractor to a factory-style Sanden A/C system with this OE-grade conversion kit from AP Air. The 990-4212R is the premium step up from a standard Sanden conversion — built to OE specifications for a cleaner, more reliable installation that closely mirrors how the factory would have done it.
What's Included (SKU: QFS-990-4212R)
This is a complete, all-in-one kit. Everything needed for a full A/C conversion is in the box:
- OE-Style Sanden Compressor — direct-fit rotary compressor built to original equipment specifications
- Receiver Drier — new desiccant to eliminate moisture from the system
- Expansion Valve — precisely controls refrigerant flow for optimal cab cooling
- O-Ring Kit — all seals required for a leak-free, R134a-compatible installation

OE vs. Standard Sanden Conversion — What's the Difference?
The 990-4212R is built to original equipment specifications, meaning the compressor mounting, porting, and hardware are matched to John Deere's factory design. This results in a cleaner installation with less adaptation required compared to a universal Sanden conversion kit. If you want the closest thing to a factory A/C system using modern R134a components, this is the kit.
Installation Notes
- Flush the system thoroughly before installing to remove residual mineral oil from the original A6 compressor
- Use PAG oil specified for the Sanden compressor — do not mix with old mineral oil
- Replace all O-rings with HNBR (green) O-rings rated for R134a (included in kit)
- Have the system professionally evacuated and recharged with R134a refrigerant
