Black Silicone Tubing Guide

Black Silicone Tubing Guide

Black silicone tubing is used as a key part in many different applications: be it liquid handling, transferring of gas, or even as a protective finish for wiring and other electrical structures. Since silicone is incredibly durable and non-toxic, it can also be used in the medical, food, and pharmaceutical industries. If you’re in a need of black silicone tubing of excellent quality and high resistance to heat, make sure to check out our wide collection of variously shaped and sized silicone tubing products. 

Now, as we’ve mentioned above, black silicone tubing comes in many different sizes and diameters. In order to make it a bit easier to understand, we categorized the products into three groups depending on their sizing: small, medium, and large. Smaller silicone tubing is mostly used for electrical sleeving, as it’s incredibly flexible and acts as an excellent electrical insulator. Again, not all silicone materials are manufactured in the same way, so make sure to check the product specs before ordering, especially if you’ll use the tubing for insulation purposes.

Medium-sized silicone tubing is mostly used for carrying gas, liquids, and powders, which makes it important for many manufacturing processes conducted in the food industry. As you may guess, not all silicone materials are suitable nor hygienic enough to be used in such processes, so take extra care and check whether the tubing material is FDA approved or not before involving them in a process that involves food or pharmaceutical consumables.

Large silicone tubing is utilized for constructing air ducts and other similar large-scale applications.  As you already know, silicone is one of the best materials for these types of applications due to its flexible and highly resistant properties. Again, these are only the most common types of black silicone tubing and their respective applications, so don’t hesitate to seek further information if necessary. 

Silicone Tubing Size Catalog

Compare inside diameter, outside diameter and listed wall thickness across silicone tube ranges. Confirm the material grade and application requirements for the selected part.

Food grade silicone tube

Compare Inside Diameter and Outside Diameter in mm, together with the listed Thickness and Colour. The cross-section drawing identifies the bore and outside diameter; confirm the selected tube material and service requirements.
