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

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!

The Dog LOVES IT!
I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!

My Golden Retriever’s favorite
We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.
