Description
Silicone, Flexible Tube, 2mm ID, 4mm OD, White 2354805 — BOLTON SKU 55345.
About the silicone flexible tube 2mm 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. BOLTON’s own quotation record for the item lists it in 50 m coils, which is the usual put-up for small-bore silicone tube of this size. Silicone tubing is a general-purpose workshop and equipment material: the elastomer stays flexible across a wider range of service temperatures than common organic rubbers, and it is chosen where a soft, kink-resistant, non-marking tube is wanted. Typical duties for a 2 mm bore 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 spacer or grommet material. Pressure, temperature and any food-contact or compliance ratings depend on the manufacturer’s grade and should be confirmed at quotation stage.

Typical applications
