Product Introduction RQ8393150022 Quick Connector is a snap-fit pipe connection fitting widely used in diesel truck SCR aftertreatment and fuel delivery circuits. It creates fast, leak-free connection between flexible hose and rigid pipeline for urea or diesel fuel circuit. This aftermarket replacement fitting solves liquid leakage, accidental disconnection and fault codes triggered by damaged locking clips, aging internal O-rings and cracked plastic housing of original connectors, maintaining stable fluid transmission and protecting sensitive fuel and urea injection components for commercial logistics vehicles.

Product Advantages Made of urea-resistant reinforced PA composite plastic with excellent chemical resistance against AdBlue and diesel oil. Built-in rubber O-ring ensures reliable sealing under working pressure and temperature fluctuation. Snap lock design enables tool-free assembly and disassembly, greatly cutting maintenance time. Each connector undergoes air tightness testing before shipment, compact structure and strong anti-vibration performance for heavy-duty truck pipeline repair.

Applicable Models Fit for multiple diesel commercial truck models, commonly installed on urea pipeline and fuel circuit assembly of light and heavy-duty logistics trucks equipped with SCR emission system.
