What Is Flexible Gooseneck Tube ?

A Flexible Gooseneck is made of a spring and a sectional wire, commonly made with , Stainless Steel,Brass,Carbon Steel,Galvanized Steel.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.

1.-Weight of the gooseneck to be supported.

- Basically, we need the following information before we can provide the best solutions:
This critical factor determines the size of the flexible gooseneck and limits the length that can be used. There are 2 different ways of loading, horizontal positions or vertical when bent a certain degree, it depends on different applications.

3.- Connectors, Screws, Fittings and Joints on both ends of the Flexible Gooseneck A

3.- Connectors, Screws, Fittings and Joints on both ends of the Flexible Gooseneck Arm

Flexible Gooseneck Tubes always act as a supporting and connecting character, besides 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 types of male and female threads, we are available for all kinds of thread types in metric thread system, British inch (Whitworth) thread system as well as US standard thread system. If they are not the standard types as mentioned above or with the irregular shapes, please provide us with the drawings or pictures, we can turn all shapes of fasteners 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 enables the Flexible Gooseneck Tube to match other connecting parts and keep them uniform. Another important purpose is to make them anti-corrosive during long-term use. Options: -Electroplating: Black, Chrome, Nickel, Zinc, Sandblast - Painting (in colors): Wet, powder, sprayed, baked -Plastic coated (in colors): PE heat shrink
