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

We threw it away
Color: Grey
This thing cannot stand on its own, the side bars bend since it is not sturdy enough to handle the material screens. After assembly, I was so mad at it, the pleasure of crushing it was better than returning it. I tryed to think of other ways to use it, but could not… i kept the screens, they are the strongest part of this thing. Very disappointing

Works well
Color: Beige
Does the trick for privacy and some noise blockage. This takes two people to put together. The construction make it easy to assemble, but makes it just as easy to come apart on its own.

Rustic Wall Shelves That Just Work
Size: 17inch, Color: Black
I bought these six floating shelves to add some storage and a cohesive look to a few walls around the house. The set has a rustic real wood vibe with an industrial edge, and the black finish keeps things feeling clean and understated. It turned out to be a practical way to create space without committing to a bulky cabinet, and I appreciated having multiple pieces to arrange in different rooms. Installation was straightforward. The package includes 12 brackets, wall anchors and screws, plus clear directions, so I could get them up without much hassle. It takes about eight minutes to mount each shelf, and the hardware feels solid. The shelves can hold around 20 pounds each, which is plenty for everyday items like books, a plant, an alarm clock, or framed photos. In use, the look is exactly what I wanted: sturdy, simple, and able to blend with existing decor across the bedroom, bathroom, kitchen, and living room. The real wood surface and the exposed metal brackets give a cohesive, rustic vibe that elevates plain walls and makes it easy to rotate items in and out. One small note is that the boards are 17 inches long and about an inch thick, so planning spacing and wall space matters a bit. The brackets being visible is part of the look, not a flaw, but it means accurate mounting is important. Overall I am very pleased with the set and it earns a solid five stars.

I love how these look in the nook in my bathroom. I needed 6 inch shelves and this was way easier than ripping 8 inch from the hardware store
