Outside Form
State the required circular format and the space available around the complete profile.

LED Silicone Tube Shape
Round silicone tube formats provide a circular external form for exposed light lines and assemblies viewed from more than one direction.
Profile Overview
Check the outside diameter, usable internal channel and visible emitting area before selecting a round silicone tube.

Show the available space, support points and how the circular tube will be held.
Compare the cavity and strip orientation with the board, component and cable dimensions.
Show which sides must be visible; a round outside form alone does not establish 360-degree emission.
Profile View
Use the cross-section to confirm the internal structure and support method, then define which area should emit from the installed viewing position.

Review the internal channels, support points and available assembly space.

Confirm the intended emitting area rather than assuming the full circumference emits.
Final light appearance is reviewed with the selected LED strip, silicone profile, assembly and intended viewing position.
Profile & Installation Options
Round silicone tubes are empty housings for a separately selected LED strip. Review the internal channel, outside diameter, visible sides and supports as one assembly. They are not interchangeable with a powered 16 mm round LED Neon Flex.

| Profile reference | Diameter | Material / finish | Strip & mounting details |
|---|---|---|---|
| D20 | 20 mm outside diameter | Silicone housing | Check the internal strip channel and component height for the selected version. D20 PVC mounting bracket is selected for the matching round tube. |
| D22 cord-covered format | 22 mm outside diameter | Silicone with cotton cord covering | 8 mm PCB reference. Confirm the required surface appearance and use conditions. D22 PVC bracket and D22 end caps. |
D20 is offered here as an empty silicone housing, not a complete waterproof lighting system. Environmental protection depends on the selected assembly, connections and sealing method. For D22, do not assume the cord covering has the same use conditions as bare silicone.
Selection Check
Use the actual strip, route and surrounding installation to confirm the profile rather than selecting from the outside appearance alone.
State the required circular format and the space available around the complete profile.
Provide the LED strip and component information needed to review the internal fit.
Mark the intended visible light area rather than assuming the whole circumference emits.
Show how the round profile will be held, suspended, inserted or assembled.
Include the installation route, tightest curve and any transition into a concealed area.
Identify the power location, cable direction and end details that affect the assembly.
Existing or Custom


Choose an available round format when its cross-section, strip space and installation interface match the required assembly. A round silicone tube for an LED strip needs a section showing the usable inner channel, strip orientation and support points. The outside diameter is not the LED strip width; compare the internal-space fit checklist with your strip.
Specify the sides that should remain visible. A circular outside form does not by itself establish 360-degree emission. If you need a complete light rather than an empty housing, compare the round and semi-round LED Neon Flex configurations.
Use a drawing, sketch or sample when the external form, internal channel, light face or connection detail must change.
Application Review
Share the viewing position, mounting route and available space so the tube can be reviewed within the actual detail.

Questions
It is a silicone lighting profile identified by its circular external form. The selected cross-section still needs to be checked against the LED strip, visible light face and installation.
Provide the strip width, maximum component height, a clear specification or photograph, and any connector or joint that must fit inside the profile.
Custom dimensions and cross-sections are available when an existing profile does not fit the installation. Send a drawing, sketch or physical sample for review.
The minimum order quantity for LED silicone tubes starts from 200 m. Include the estimated quantity and required profile format with the request.
Yes. A sample can be arranged for the selected profile. Sample details and shipping are confirmed with the request; shipping is paid by the recipient.
