When purchasing an Industrial Grade Extruded Silicone Tube, it is easy to focus on the material, temperature resistance, or application first. But for many industrial installations, dimensional accuracy is just as important.
A tube can have the right material and still be difficult to use if its inside diameter, outside diameter, wall thickness, or length does not match the actual installation.
Inside Diameter Determines the Connection
The inside diameter is usually the first dimension to confirm because it needs to correspond with the component, fitting, or pipe being connected.
However, the required size should not be estimated from the nominal pipe size alone.
The actual connection method matters. A tube installed over a fitting may require a different fit from one inserted into another component. The required clearance, insertion depth, and sealing method should therefore be considered before confirming the final diameter.
For custom orders, providing the actual mating component or connection dimensions can be more useful than simply stating a nominal size.
Outside Diameter Matters Too
The outside diameter is often overlooked when specifying silicone tubing.
This becomes important when the tube is installed with a clamp, through a hole, inside a guide, or alongside other components.
For example, two tubes can have the same inside diameter but different wall thicknesses. Their outside diameters will therefore be different, which may affect the available installation space or the selection of the corresponding clamp or fitting.
For an Industrial Grade Extruded Silicone Tube, inside diameter and outside diameter should be considered together.
Wall Thickness Changes the Tube's Behavior
Wall thickness is not simply a dimensional value.
It can affect the tube's flexibility, resistance to deformation, connection fit, and overall handling during installation.
A thin-wall tube may be easier to bend or route through a confined space. A thicker-wall construction may be preferred when the application requires greater structural support.
The correct choice depends on how the tube will be installed and used.
There is therefore no universal "best" wall thickness. It should be determined according to the application rather than selected only because a particular size is commonly available.
Avoid Excessive Stretching During Installation
One common installation mistake is using a tube that is slightly undersized and relying on stretching to make it fit over a larger connection.
Silicone tubing is flexible, but flexibility should not be confused with unlimited stretchability.
Excessive stretching can reduce the wall thickness around the connection and may place additional stress on the material. It can also make the connection more difficult to secure correctly.
The tube should ideally fit the connection without requiring excessive force.
Check the Tube After Installation
Once an industrial silicone tube has been installed, check the connection before putting the system into regular operation.
Look for:
Uneven compression around the connection
Excessive bending near the fitting
Kinks or flattened sections
Contact with sharp edges
Interference with moving components
Signs of leakage after operation
For longer tubing runs, supporting the tube at appropriate points can also help prevent unnecessary movement or sagging.
Provide Complete Information When Ordering
For a custom Industrial Grade Extruded Silicone Tube, the most useful specification is rarely just "silicone tube + diameter."
A more complete request should include the inside diameter, outside diameter or wall thickness, length, working temperature, pressure conditions, transported medium, connection method, and installation environment.
If the tube needs to meet a particular industry or project requirement, that should also be communicated before production.
Getting the dimensions right at the specification stage can reduce installation problems later and make the finished tube much easier to integrate into the system.
Haidu provides customized Industrial Grade Extruded Silicone Tube solutions with different diameters, wall thicknesses, lengths, and construction options according to specific industrial and OEM/ODM requirements.
