Gooseneck Tube
Stand Tube (DFM)
Made from a combination of round and triangle rods which allows the tube to be bent easily, and hold a bent position. The working load can be enhanced by inserting a sub-strength material, and the exterior can be enhanced with metal plating, painting, or PVC sheathing.
Features and Attributes:
- Combination of round and triangular rods
- Can be bent easily
- Holds a bent position
- Can enhance the working load by inserting a sub-strength material
- Exterior can be improved with metal plating, painting, or adding a heat shrink tube sheathing
- RoHS Compliant
Standard Product:
- All gooseneck tubing is custom and made to order. Please view the technical specs for a guide on sizing.
- Materials: A mix of hard and soft steel wire rods are used to make the tube flexible, and hold a bent position.
Services Available Upon Request:
- Pliability of the tube can be modified upon request.
- End fittings are available. They are custom per order, please have a drawing or spec sheet available.
- Surface Treatment: Plating (chrome, black chrome, nickel, zinc), Painting (sprayed, burnt), and Heat shrink tube sheathing available.
Common Applications:
- Light guides
- Microphone stands
- Light stands
- Fixed auto accessories
Stock Level: Non-stock made to order item. General lead time is 6-8 weeks.

PVC Sheathing Varieties
| Figure Num. | Sheathing Variety | Part Number Code | Features |
| 1 | Tight-Fitting | KSP- __N | – Standard item – PVC fills the spiral valley to make the finished surface even and smooth. |
| 2 | Vacuum Sheathing | KSP-__N-B | – During processing, sheathing is applied in a vacuum. – The finished surface maintains the spiral pattern of the coil. |
| 3 | Bagging Sheathing | KSP-__N-F | – Sheathing is applied only on the surface of the tube and the spiral valley contains no PVC. The surface of the sheathing will be completely smooth. |
| N/A | Heat Shrink Sheathing | KSP-__N + Shrink tube type# | – Please contact us for more details. |
