Capillary tubing can be described in various ways, depending on the context in which it is being used. One synonym for capillary tubing is microbore tubing, which refers to its small diameter. Another synonym is stainless steel tubing, as it is commonly made from this material. Additionally, it can also be referred to as thin-walled tubing or small-bore tubing due to its thin walls and narrow diameter. Capillary tubing is often used in applications that require precise flow control, and as a result, it is also known as precision tubing or precision capillary tubing. These synonyms can be used interchangeably to accurately describe the characteristics and applications of capillary tubing.
