About the Silicone Flexible Tube 2 mm ID
This item is flexible tubing extruded from silicone rubber, with a 2 mm inside diameter (bore) and a 4 mm outside diameter, supplied in white; the wall thickness implied by those dimensions is 1 mm. Silicone tubing is a general-purpose workshop and equipment material: the elastomer remains flexible across a wide range of service temperatures compared with common organic rubbers, and it is widely chosen where a soft, kink-resistant, non-marking tube is needed. Typical duties for small-bore silicone tube of this size include low-pressure transfer of air and liquids, pneumatic sensing lines, sleeving over wires or fasteners for protection and identification, vibration isolation of small components, and use as a spacer or grommet material in assemblies. Specific pressure, temperature and compliance ratings depend on the manufacturer’s grade and should be confirmed at quotation stage.
