Solid silicone tubing
The term solid silicone tubing can be ambiguous. A silicone tube has an internal passage, while a solid silicone cord or rod does not. Start with a section drawing that shows whether a bore is required and what the component must do: carry a medium, cover a part or provide a solid resilient profile.
Compare dimensions only after the section is clear. For sizes described within a 1 mm to 40 mm range, identify which diameter is being measured and specify tolerances. A hardness value also needs its scale and tolerance; it should be considered alongside wall geometry or solid-section size when assessing flexibility.
The chosen silicone formulation must suit contact with fluids, operating temperature and repeated movement. Storage and use both affect the condition of a part. Inspect for cracking, tackiness, deformation or loss of function rather than assuming that a component will perform unchanged for a fixed number of years.
Product specifications
- Section definition
- Distinguish hollow silicone tubing from solid cord or rod.
