Maintain Emissions with the 2028048PE DEF DOSER GASKET
The 2028048PE DEF DOSER GASKET is a small but essential part of your PACCAR engine’s emissions system. It forms a secure seal between the DEF doser injector and the exhaust stream, helping to prevent leaks, reduce emissions faults, and maintain compliance with modern environmental standards.
Why Gaskets Matter in DEF Systems
Diesel Exhaust Fluid (DEF) systems play a key role in reducing NOx emissions through Selective Catalytic Reduction (SCR). If the gasket between the doser and the exhaust system wears out, DEF leaks can occur, leading to reduced efficiency, error codes, and even vehicle derating. Replacing it with a high-quality 2028048PE DEF DOSER GASKET helps avoid these costly issues.
This PACCAR-compatible gasket is built from high-temperature, chemical-resistant materials. It’s designed to withstand extreme operating conditions while maintaining a long-lasting, leak-free seal. Proper installation ensures accurate DEF dosing and optimal SCR performance.
Reliable Performance for PACCAR Engines
Manufactured with heat-resistant materials, this DEF doser gasket offers long-term durability even under high exhaust temperatures. Its PACCAR compatibility guarantees a perfect fit, making installation quick and easy for service technicians or fleet operators.
When Should You Replace the Doser Gasket?
Signs of a failing gasket include:
- Visible DEF leaks
- Strong ammonia smell
- Fault codes related to DEF dosing
- Reduced fuel efficiency
If you notice any of these, it’s time to install a new gasket.
