Modern emissions systems don’t allow much margin for error. For SANY equipment powered by the Cummins ISB 6.7L engine, the DEF (Diesel Exhaust Fluid) head unit is a critical sensor and dosing controller. The OEM 160599000138A005 version ensures your aftertreatment system receives accurate data on DEF fluid characteristics—without it, you may face warning lights, emissions faults, or unexpected derates.
-
Monitors DEF fluid level, temperature, and urea concentration and relays that information back to the engine’s ECU
-
Regulates precise dosing of DEF into the exhaust stream so the SCR (Selective Catalytic Reduction) system can meaningfully reduce NOx emissions
-
Built to match OEM 160599000138A005 tolerances, ensuring drop-in compatibility with SANY / Cummins ISB systems
-
Helps guard against fault codes, emission warnings, and engine derates that often stem from sensor drift or errors
-
Designed to tolerate harsh conditions: vibration, temperature cycling, and exposure to corrosive DEF chemistry
-
Equipped with a 40-micron filter to help prevent contamination that can degrade sensor or injector performance
Ignoring a misbehaving DEF head is a risk. By installing the proper OEM 160599000138A005 DEF Head Unit, you restore integrity to your emissions feedback loop, protect your SCR system, and reduce the chance of surprise failures. In emissions control, precision is everything—and this small component plays a big role.
