Provide installation manual, tool-free assembly, no additional modification required.
Military-Grade Material, Dual Guarantee of Sealing Durability
 
air hose quick connectors​ main body made of high-quality nylon (PA) and brass, resistant to fuel corrosion, high temperature (-40℃~120℃) and vibration
 
Sealing gasket made of fluoroelastomer (FKM), passed 100,0 times pressure test (0.3-0.5MPa), no leakage risk
Leak off Pipe Connector
Designed specifically for diesel engine common rail injection systems, it connects leak off pipes to injectors, enabling the recirculation of excess fuel, precisely controlling fuel system pressure and avoiding leakage risks.
Core Features                 
Structural Design: Offers 3 interface configurations (T-type, L-type, Straight type) to adapt to different engine compartment layouts; metal snap-on connection with an insertion force ≥50N, ensuring no dislodgement during vehicle vibration.
 
Material Performance: Body constructed from brass + nylon PA66, resistant to fuel corrosion and high temperatures (-30℃~100℃); sealing gasket made of fluoroelastomer (FKM), passing 100,000 cycles of pressure testing (0.2-0.4MPa) with no fuel leakage.

CompatibilityAdvantage:Tool-free,hand-installable,with interface dimensions matching original equipment 1:1, compatible with mainstream injector brands such as Bosch, Denso and Delphi.
Application Scenarios          
Aftermarket replacement and original equipment supply for passenger car diesel engines and light commercial vehicle injection systems.

SCR Quick Connector

Compatible with commercial vehicle SCR urea injection systems, connecting urea tanks to injectors to ensure stable delivery of urea solution, helping engines meet exhaust emission standards. 
 
Core Features       
Industry Certification: Strictly designed in accordance with SAE J2044 standards, resistant to urea solution corrosion with no cracking or swelling after long-term immersion.

Sealing Technology: Dual-seal structure (O-ring + ferrule), withstanding high pressure (0.5-1.0MPa) and remaining flexible in low temperatures to prevent urea leakage and crystallization.
 
Installation Design: Quick-plug structure with anti-misinsertion clips, locking with an audible "click" during installation to effectively prevent system failures caused by reverse connection.
 
Application Scenarios    
Maintenance and modification of SCR systems in heavy-duty trucks, buses and engineering vehicles

Fuel Line Connectors
Used in engine fuel delivery systems, connecting fuel filters, fuel pumps and engine fuel rails to achieve efficient, sealed transmission of gasoline/diesel.
 
Core Features     
Material Selection: Gasoline vehicle-specific models use nylon PA12, resistant to ethanol gasoline (E10/E85) corrosion; diesel vehicle-specific models incorporate antistatic agents to prevent fuel safety hazards caused by static electricity.

Specification Coverage: Interface sizes include 6.3mm, 8mm, 10mm, 12mm to meet fuel flow requirements of different displacement engines; available in straight, 45° elbow and 90° elbow configurations to adapt to complex pipeline routes.

Safety Performance: Built-in one-way valve that automatically cuts off fuel flow when the pipe is disconnected, preventing fuel splashing; compliant with EU REACH environmental standards and automotive industry safety regulations.
 
Application Scenarios    
Fuel systems of passenger cars (gasoline/diesel) and fuel pipeline modification of light commercial vehicles.
