Micro rubber tubing

Micro rubber tubing

Can you assume what the main quality of micro rubber tubing is? That’s right. It is its size. If you want to learn more about this, you should explore our website. However, generally speaking, the smallest internal diameter is usually 0.10mm, the wall thickness starts at 0.5mm, and the thickness of one layer can be as low as 0.005mm. When it comes to the number of layers that can be combined in a micro rubber tubbing, we are talking about four of them, although this number can differ between manufacturers.

Micro rubber tubing is most commonly used in the pharmaceutical and food processing industries. Due to this reason, the rubber used in the manufacturing of this tubing must meet specific criteria and requirements. Naturally, the most significant one is in correlation with our safety. Food processing consists of several aspects, and all the tools used need to be safe since they all come in direct contact with the food we will later eat. Because of this, the silicone cannot include any additional chemicals or substances. Therefore, it must follow all the regulations, and the FDA needs to approve it. This is especially important when it comes to medication manufacturing. If there were any additional substances, they could have an effect on the final product. 

What’s more, micro rubber tubing needs to be of the highest quality. But, what does that exactly meaning, besides the above-mentioned properties? Well, in a nutshell, this tubing must be flexible and durable. At the end of the day, it will be used constantly during the production process, which is why it needs to be able to withstand all sorts of factors. Because of this, before placing the next order, you have to go over the properties of the items. Plus, once you find the right manufacturer, you can order more micro rubber tubing than you actually need since it has a long shelf life.

Discuss Your Requirements

Product specifications

Product form
Hollow elastomer tubing for a fitted line or sleeve
Material options discussed
Silicone. Choose one formulation for the actual contact and loading conditions.
Application focus
Pharmaceutical fluid handling, food-processing equipment and industrial fluid lines. Size the part against the selected assembly.
Dimensions to confirm
Inside diameter, outside diameter, wall thickness and cut length. Match these to pharmaceutical fluid handling and food-processing equipment.
Small-bore control
Set bore and wall tolerances, check lumen continuity and choose fittings that do not close or distort the passage.
Contact conditions
Food ingredients and medicinal contents: define concentration, temperature and contact time, then check compatibility with the chosen compound.
Line layout
Check bend radius, unsupported spans and clearance at both connections.
