Description
If you’ve been dealing with AdBlue system warning lights or trouble codes on your Tier 4 tractor, this little gasket might be the simple fix you need. When the AdBlue injector gasket starts to fail, it can cause pressure losses and contamination that trigger expensive system faults. Getting the injection unit properly sealed keeps your SCR emissions system running clean and your tractor working without costly shutdowns.
Key Features
- Precision-cut for exact fit on AdBlue injection units used with 55472 injectors
- Chemical-resistant material designed to handle AdBlue fluid exposure without degrading
- Creates reliable seal to prevent air infiltration and fluid contamination
- Direct replacement gasket – no modifications or special tools needed
Built for Real Farm Work
This gasket works with the AdBlue injection systems found on New Holland T6 and T7 series tractors as well as Case Maxxum and Puma models. These are the reliable mid-to-large frame tractors handling everything from cultivation and planting to hay production and heavy tillage work where you need full power and can’t afford emission system problems.
Made to Last
The AdBlue injection system operates under pressure with corrosive urea solution, so this gasket is engineered specifically for that environment. The material won’t break down from chemical exposure or temperature cycling, and it maintains its sealing properties even with the vibration and stress of field work.
Installation Notes
When replacing this gasket, clean the sealing surfaces thoroughly and make sure no debris gets into the injection system. AdBlue systems are sensitive to contamination, so keep everything clean during installation. This gasket works specifically with the 55472 injector unit, so verify your part numbers before ordering.
