Thin wall silicone tubing

Thin wall silicone tubing

Thin wall silicone tubing has a very common application in medicine, but also in many other spheres. It is used so often in medicine for two reasons. The first reason is the suitability of silicone for contact with humans because it is non-toxic and is suitable even for contact with the inside of the body and food. And also since we are talking about thin wall silicone tubing, it is ideal for anesthesia, in emergencies, as a catheter and for many other medical purposes. Machine made for helping with and treating obstructive sleep apnea also contains thin wall silicone tubing. It can be also used as a cover if you have to keep something sterile.

Hospitals are of course not the only places where we can find thin wall silicone tubing in wide use, but also in various industries, even in the food industry. Food-safe silicone tubes are an indispensable part of refrigerators, freezers, coffee machines, and are even used in wineries. Thin wall silicone tubing can be used anywhere where tubing is needed that is resistant to water and weather, and also resistant to large changes in temperature. Silicone withstands from minus 75 to 280C so it is very difficult to find an environment where it is not suitable.

The diameter, both outer and inner, can be very different, and you can also just choose the diameter of thin wall silicone tubing. As for wall thickness, the thickness rarely exceeds 0.15 mm, but of course this is also subject to customization. Wall thickness is very often about 0.05 mm which is very thin, but will be suitable for different purposes.

Silicone is environmentally friendly and non-toxic, so it is increasingly used. It is mostly transparent or white, but can be other colors. It can be black, red, blue or whatever color you need.

Product specifications

Product form
Hollow elastomer tubing for a fitted line or sleeve
Material
Silicone. Specify the compound grade for the selected service.
Application focus
Medical-device assemblies, food-processing equipment, catheter assemblies and coffee-making equipment. Size the part against the selected assembly.
Dimensions to confirm
Inside diameter, outside diameter, wall thickness and cut length. Match these to medical-device assemblies and food-processing equipment.
Wall control
Dimension wall thickness separately from the bore; check the required bending behavior and connection fit at that thickness.
Contact conditions
Medicinal contents, food ingredients and water: define concentration, temperature and contact time, then check compatibility with the chosen compound.
Exposure to evaluate
Outdoor weather. Validate the selected material under the combined conditions.
Line layout
Check bend radius, unsupported spans and clearance at both connections.
