Motorad Diesel Exhaust Fluid Filler Cap

The Motorad Diesel Exhaust Fluid (DEF) Filler Cap line gives you OEM-grade replacement DEF caps, also called diesel emissions fluid caps or DEF tank caps. Each cap seals the DEF filler neck. This keeps diesel exhaust fluid from leaking or spilling and keeps contaminants out of the system.

Key Features:

• Made from high-quality, heat-resistant materials for long-term durability
• Designed for an optimum fit and built to meet or exceed OEM specifications
• Helps keep pollutants out of the environment by preventing DEF leaks and spills
• Restores the diesel emissions fluid system to proper operation when it replaces a missing, damaged or worn cap
• Blue color with indicator markings for easy identification as a DEF cap
• A worn or missing cap can cause an inspection failure in some states, so replacing it matters

Motorad is a well-known supplier of engine cooling and emissions-related replacement parts. Choose the cap that matches your application, because attachment style and thread design differ between part numbers in this line.
