The 1116712501032 Urea Tank Cap is a precision-engineered sealing component designed to securely close the urea (DEF) tank on SINOTRUK Howo heavy-duty trucks equipped with SCR emission control systems. As a trusted supplier of genuine Sinotruk howo parts, we offer this urea tank cap as a direct OEM replacement, manufactured to the exacting standards of the original equipment. The 1116712501032 is crafted from high-quality, corrosion-resistant materials with a precision-molded sealing ring and a robust locking mechanism, ensuring a leak-proof seal, preventing contamination of the urea solution, and safeguarding the SCR system from performance issues under the extreme conditions typical of heavy-duty trucking.
This urea tank cap plays a critical role in maintaining the purity and quality of the diesel exhaust fluid (DEF), which is essential for optimal SCR operation and emissions compliance. Its precision-engineered fit ensures a tight seal that prevents dirt, moisture, and debris from entering the tank, while the integrated pressure relief system (if applicable) maintains proper tank ventilation. The 1116712501032 is built to withstand vibration, temperature fluctuations, and chemical exposure, delivering dependable service over thousands of miles.
OEM direct replacement • Corrosion-resistant materials • Leak-proof sealing • SCR system compatible
The 1116712501032 urea tank cap is a purpose-built component for SINOTRUK Howo trucks with Selective Catalytic Reduction (SCR) systems. It is designed to seal the DEF tank securely, preventing leaks and contamination while allowing for proper ventilation.
Manufactured from high-grade materials, the cap features a precision-molded sealing ring that provides a tight, leak-proof seal against the tank neck. The locking mechanism ensures the cap remains firmly in place even under severe vibration, while the corrosion-resistant construction protects against degradation from urea solution and environmental exposure.
This urea tank cap is essential for maintaining the quality of the diesel exhaust fluid, which is critical for SCR system efficiency and emissions compliance. Its robust construction and precision manufacturing ensure reliable performance over extended service intervals.
The 1116712501032 urea tank cap is specifically designed for SINOTRUK Howo heavy-duty trucks equipped with SCR emission control systems, including Howo A7, T7H, and other models that use the standard HOWO urea tank filler neck. It is also compatible with certain Foton Auman GTL models.
This cap is essential for a wide range of applications, including long-haul trucking, regional distribution, construction, and mining, where maintaining DEF purity and SCR system efficiency is critical for emissions compliance and engine performance.
When replacing, always verify the filler neck diameter and locking mechanism compatibility. The 1116712501032 is a direct-fit component that simplifies maintenance and ensures optimal SCR system reliability.
Installing the 1116712501032 urea tank cap is a straightforward process. Begin by removing the old cap and thoroughly cleaning the filler neck threads and sealing surface to remove any dirt, urea crystals, or debris.
Align the new cap with the filler neck and turn it clockwise until it is fully seated and the locking mechanism engages. Ensure the cap is tightened securely to achieve a proper seal. Do not overtighten, as this may damage the sealing ring.
Regular inspection of the cap is recommended during routine maintenance. Look for signs of damage to the seal, corrosion, or wear on the locking mechanism. If the cap shows any signs of damage or difficulty sealing, replace it immediately to maintain DEF quality and SCR system performance.
Reusing old caps is not recommended, as the seal may have degraded or the locking mechanism may have worn over time. Always use a new cap when replacing to ensure reliable sealing and protection of the urea solution.
The 1116712501032 urea tank cap is manufactured in an ISO 9001-certified facility, with stringent quality controls applied throughout the production process. The materials are selected for their resistance to urea and other chemicals, and each cap is inspected for dimensional accuracy and seal integrity.
Every cap undergoes leak testing and locking mechanism function checks to ensure it meets OEM specifications. The sealing ring is tested for flexibility and durability, and the surface finish is verified for corrosion resistance. We also perform random sample testing for chemical resistance and thermal cycling to confirm that the cap performs reliably in real-world conditions.
Our commitment to quality ensures that the 1116712501032 delivers reliable, consistent sealing performance, reducing the risk of DEF contamination, crystallization, and SCR system faults. With a comprehensive warranty, this cap offers peace of mind for fleet operators and owner-operators alike.
