Description
If you’ve got a newer Case IH tractor with SCR emissions, you know that blue bottle under the hood is just as important as the diesel tank. When your AdBlue cap starts cracking, leaking, or won’t seal properly, you’re looking at contaminated DEF fluid and potentially expensive aftertreatment system problems. This replacement cap keeps your diesel exhaust fluid clean and your emissions system running like it should.
What You’re Getting
- Secure seal that keeps moisture and dirt out of your AdBlue tank
- Proper venting design prevents vacuum buildup while maintaining fluid quality
- Durable construction built to handle daily use and weather exposure
- Direct replacement that threads on just like the original
Built for Real Farm Work
This cap is designed for Case IH tractors across the CVX, Maxxum, and Puma series that came equipped with SCR emissions systems. Whether you’re running a CVX1170 through corn stubble or using a Puma 180 for heavy tillage work, these tractors depend on clean AdBlue to keep the aftertreatment system working properly and avoid those expensive dealer visits.
Made to Last
DEF is corrosive stuff, and a cheap cap won’t last long. This one uses materials that resist the chemical effects of diesel exhaust fluid while maintaining a reliable seal. The threads stay smooth, the gasket stays flexible, and the cap keeps doing its job season after season.
Good to Know
Installation is straightforward – just unscrew the old cap and thread on the new one until it seats properly. Don’t over-tighten, as this can damage the seal. If you’ve been dealing with DEF contamination issues, this is a good time to have your fluid tested and possibly replaced to avoid expensive aftertreatment repairs.
