How to choose a Flexible Gooseneck Tube?
A Flexible Gooseneck is made of a spring and a sectional wire, which gives it its unique mechanical characteristics and to keep a given shape and position. With their special combination of flexibility and rigidity, Gooseneck Tubes can be used to create supports and arms whose position can be adjusted as needed. 
Basically, we need to obtain the following information before we give out the best solutions: 1,- Weight of the gooseneck to be supported/loaded.
This critical factor decides the sizes of the flexible gooseneck and limits its length to be employed. There are 2 different loading ways, Horizontal positions or Vertical when bended a certain degree, it depends on different applications. 2,- Outer Diameter, Inner Diameter and Length 
By defining its positions to be used, we will provide you the best combinations of the material used and the most suitable types to your projects. 3,- Connectors, Screws, Fittings and Joints on both ends of the Flexible Gooseneck Tube 
Flexible Gooseneck Tubes always act as a supporting and connecting character, besides of injecting and gluing them with other parts, in most cases, there should be some kinds of connectors and fittings to join the parts of applications. Usually, there are 2 main kinds of Male and Female Threads, we are available for all kinds of thread type in Metric Thread System, British Inch(Whitworth) Screw Thread System as well as US Standard Screw Thread System. If they are not the standard types as mentioned above or with the irregular shapes, please provide us the drawings or pictures, we can lathe out all shapes of connectors with different machines and techniques. 4,- Flexible Gooseneck Finishing & Treatment Using a wide range of surface treatment and finishing to achieve various looks and colors, which enable the Flexible Gooseneck Tube to match other connecting parts and keep them uniformed. Another essential purpose is to make them anti-corrosions during a long term usage. Options: -Electro-Plating: Black, Chrome, Nickel, Zinc, Sandblast -Painted (in colors): Wet, Powder, Sprayed, Burnt -Plastic Covered (in colors): PE heat shrunk
