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

Compatible John Deere Models

  • John Deere 4040 & 4040 Euro
  • John Deere 4230
  • John Deere 4240, 4240 Euro & 4240S
  • John Deere 4430
  • John Deere 4440 & 4440 Euro
  • John Deere 4630

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

Gorgeous!
Color: 01.Heart Cut, Style: 04. April (Diamond)
I love this necklace! I wanted something that represented my birthstone, but did not cost a fortune and could be easily replaced if it’s ever lost. I have very sensitive skin. Seriously, I’m even allergic to gold unless it’s pure. This necklace is perfect. The chain hasn’t bothered the skin on my neck since I put it on. The size is perfect for me. It sits exactly where I want it to. The pendant is a true Goldilocks - not too big, not too small, but just right! I love the way it looks in the sun! Sparkles, sparkles, sparkles! This is definitely going to be my go to, everyday piece. I highly recommend this to anyone who is even a little bit interested in buying it. You won’t be disappointed. It makes a wonderful gift for ladies and girls of all ages, or simply as a treat to yourself! Choose your birthstone or your favorite color! In fact, I’m considering which color to purchase next. Can’t say enough how much I am in love with this amazing piece!

Sparkling ✨️ Pretty
Color: 02.Round Cut, Style: 04. April (Diamond)
The chain is very nice, can adjust it to 16 to 18inches. Appears to be 925 sterling sliver. The diamond charm is about a diime in size. It's sparkling and pretty. I can't decide if the charm is to big or not for me. All in all 40. Spent on it was ok but no more.
