Aluminum Fuel Tank Fitting Production
At first, we create a detailed CAD and a mold, if die-casting is involved. Your chosen aluminum alloy will be either melted and cast into shape, or the billet will be CNC machined by milling or turning.
Each component and part are precision-machined to specific tolerances for reliable performance. We have 100 sets of 3-, 4-, and 5-axis high-precision CNC milling and turning equipment, achieving tolerances of 0.002um.
Then, we apply surface treatments to enhance the durability of your aluminum fuel tank fittings.
Aluminum Fuel Tank Fitting Application
HM aluminum fuel tank fittings and parts are suitable for use with led, unleaded, ethanol-blended, and alcohol-blended fuels. They are also perfect for propane, diesel, and gas engines.
Our fuel tank fittings are used in fuel tanks of all sorts of vehicles. For example, streetcars, racing cars, trucks, bikes, bulldozers, boats, aircraft, etc.
Additionally, weldable aluminum fuel tank fittings can be used for oil, cooler fluid, swirl pot, catch tank, and any other aluminum alloy tank.

Features


Weldable Design
We offer weldable aluminum fuel tank fittings. They are attached to socket-connect ends of an unthreaded pipe using a CPVC primer and cement—also known as a solvent weld. This allows for a cheaper design and permanent connections.
Selection of Alloys
Being one of the leading aluminum fuel tank fittings manufacturers from China, we work with:
- Acd12
- A380
- ZLD104
- Al 6082
- Al 6063
- Al 075
- Al 5052
Usually, the recommended fuel tank parts raw material is aluminum 5052, either 1/4 or 1/2 hard aluminum.
AN & NPT
You can specify thread sizes using AN or NPT measurements and types. NPT fuel tank parts have a tapered thread. AN fittings are flare-type compression fittings. You can request either of them, or even a fitting that acts as an adapter between the two types.
Chemical Resistance
At HM, we offer a wide range of surface treatments to improve durability and resistance to corrosion. For example, we offer different types of anodizing, various plating, polishing, sand blasting, coloured powder coating, and more.
Aluminum fuel tank fittings are designed using aluminum alloys. It exceeds or meets the minimum requirements of aerospace hose fittings.
Each component and part are precision-machined to specific tolerances for reliable performance. Additionally, aluminum fuel tank fittings can be welded onto the oil, cooler, fuel cell, swirl pot, catch tank, or any aluminum tank.
There are various examples of aluminum fuel tank fittings, such as:
- Threaded Diesel Fuel Cap Neck Insert for Fill Pipe
- Billet 6061 Aluminum Bung & Cap
- Half Coupling Bung / Fuel Oil Water
- Pop Up Fuel / Gas Cap Motorcycle
- Aluminum Half Coupling Bung
- Bolt-in Gas Tank Plate for Pickup Tube and Rollover Valve
- 45 Degree Fuel Fill Inlet
- Aluminum Aircraft Flush Mount Fuel Filler Cap
Aluminum fuel tank fittings will fit large and medium fuel tubing. It is also functional for pressure ports or extra fill. Moreover, aluminum fuel tank fittings can be worked with a bladder system.
An aluminum fuel tank fitting is applicable in marine fuel tanks. The fuel tank fitting includes interconnection kits and tank hose connections.
The tank hose connection has a connection, lid for the following applications:
- tank vent
- fuel filling hose
- fuel return pipe
- tank vent
- fuel suction pipe
- level sender mounting flange
- rubber seal
- mounting straps
- counter flange
The interconnection kits are ideal for twin fuel tank installations. Interconnection kits include the following:
- hose tails
- copper washers
- fiber washer
- rubber seals
- skin fittings
- gasket
- coupler
- mounting straps
Brass fittings can be used in an aluminum tank, but precautions should be taken to prevent galvanic corrosion between the two metals. Using insulating materials or coatings can help mitigate this issue.
When selecting aluminum for a fuel tank, it’s recommended to use marine-grade aluminum, such as 5052 or 5083, due to their corrosion resistance and durability.
The thickness of an aluminum fuel tank depends on various factors like the tank’s size, intended usage, and design. Generally, a thickness of 1/8 to 3/16 inches is common for smaller tanks.
Yes, aluminum is commonly used for gas tanks due to its lightweight nature, corrosion resistance, and suitability for various fuels.
To prevent galvanic corrosion between aluminum and brass, ensure proper insulation between the two metals using gaskets, seals, or non-conductive coatings.
Aluminum is compatible with metals such as stainless steel, titanium, and certain plastics. Compatibility depends on the specific application and environmental conditions.
Yes, brass and aluminum can undergo corrosion when in direct contact due to their dissimilar electrochemical properties. Proper insulation is crucial to prevent this.
Brass and aluminum can experience bonding under pressure, especially at elevated temperatures. Using anti-seize compounds or compatible sealants can help prevent sticking.
Stainless steel and aluminum can be used together, but precautions should be taken to avoid galvanic corrosion. Separation and insulation techniques are essential to prevent adverse reactions.
Yes, brass compression fittings can be used on aluminum tubing, provided steps are taken to minimize galvanic corrosion risks. Applying insulating materials is advisable.
Mixing aluminum and steel fittings can lead to galvanic corrosion. It’s recommended to avoid such combinations or implement proper insulation measures.
