Urea Injection Cap

The urea injection cap, also known as the AdBlue tank cap or DEF cap, is a crucial component of the Selective Catalytic Reduction (SCR) system used in diesel vehicles. It seals the urea (AdBlue) tank to prevent contamination, evaporation, and leaks, ensuring proper dosing of the urea solution into the exhaust system. A secure and well-fitted urea injection cap helps maintain optimal emission reduction and SCR system efficiency.

At PARTXL UAE, we supply a wide range of OEM and aftermarket urea injection caps suitable for German, Japanese, Korean, Chinese, and American vehicles. Whether for a Mercedes-Benz, BMW, Volkswagen, Toyota, Nissan, Isuzu, Hyundai, Kia, Ford, or Chevrolet, PARTXL guarantees precise fitment, chemical resistance, and long-lasting performance.

Our urea injection caps are made from high-quality, chemical-resistant plastic and rubber seals, designed to withstand urea corrosion, pressure changes, and temperature fluctuations. Each cap meets or exceeds OEM specifications, ensuring a tight seal, easy installation, and reliable long-term operation. Replacing a damaged or missing cap prevents AdBlue contamination, system faults, and emission errors.
