An fittings Male Weld Bung:
Weld Bung Title:
Heavy Duty An fitting adaptor Weld Bung An aluminium fittings for New Energy System
Forged An Fittings Introduction:
The male threaded end of AN fittings complies with AN (Army Navy) standards (commonly used specifications such as AN-8, AN-10, AN-12, etc.), and the size range of AN Male Weld Bung varies from 3AN to 20AN;
Core functions:
Interface conversion: Upgrade non-standard pipelines to AN standard interfaces and adapt to quick release connectors;
Sealed pressure bearing: suitable for high flow fuel/hydraulic systems;
Material and Processing
Main material: 6061-T6 aluminum alloy&Stainless Steel 304L, with high strength and good weldability;
Surface technology: Hard anodizing treatment to enhance wear resistance and corrosion resistance.
Manufacturing process
Cold forging forming: maintaining the integrity of metal flow lines;
Thread accuracy: AN standard;
Base type:
Straight type: used for flat welding (such as oil tanks and oil coolers);
Angle type (45 °/90 °): Suitable for complex spatial layouts (such as engine compartment pipeline steering);

| 1 5/16-12" | 16AN | 1" | 0.88" | 0.84" |
Application:
Racing fuel system (tank welding AN-10 base) hydraulic system integration (engineering machinery hydraulic tank integration AN-12 base) laser cooling machine welding AN-8 base, etc.

Sealing inspection and joint installation
Weld seam inspection
AN connector installation
Apply special anti sticking paste to the threads (to avoid metal cold welding);
Use a double opening wrench to tighten and tighten;
