What Is The Difference Between Hose And Tube?

Although often used synonymously, tubing and hose vary in one important way: hoses are usually reinforced.  Embedded braids or cables, stiffer materials, dual walls, or stronger walls are common reinforcements.  Trousers are typically used for high-pressure applications, whereas unreinforced tubing is typically used for gravity flow or low-pressure applications. There are several applications that would be suitable for either. The most important thing is to follow the manufacturer’s instructions for your particular hose or tubing. The simplest way to compare the differences between hoses and tubes is to look at the major categories in which they differ. The three categories we will investigate in this blog are as follows:

-Sizing Expressions
-Production Process


The tubing is mostly used for structural purposes. Tubing does not have to be cylindrical and is available in a cube, rectangle, and a variety of other design shapes. Depending on the application, the content will now adhere to guidelines established by a variety of standard organizations worldwide, including the International Organization for Standardization (ISO) and ASTM International (ASTM).

In this dispute, hoses are the jack of all trades. Hoses serve as a temporary solution in a variety of situations and have a wide range of applications and requirements. Hoses are typically lightweight and made of nylon, rubber, and other nonmetal materials. Hoses are typically designed for a variety of applications, and due to the variety of those applications, an in-depth discussion about the plethora of those applications is a fun topic for another day. Suffice it to say that hoses are not used for piping, but due to the variety of uses, there may be some overlap with pipe purposes.

Sizing Expressions

When it comes to tube sizing, three key measurements must be provided to determine the tube size.

  • The external diameter (OD)
  • The internal diameter (ID)
  • The wall thickness (WT)

Such measurements classify tubing into various specifications, and there are standard models available, similar to piping. Surprisingly, tube size maps make use of two new acronyms for me: BWG and SWG. BWG stands for Birmingham Wire Gauge, and SWG stands for Normal Wire Gauge (the less common of the two), both of which are tube thickness measurements that can be converted to mm or inches.

Hoses are common in their universe, but thankfully, using words we’ve already used makes it a little easier. Hoses, like tubing, calculate scale using the ID rather than the OD. The use of the internal diameter stems from a focus on hose flow rates, as the detection of the ID, OD, and length of the hose determines the flow rate through the hose. Anything referred to as a dash network control by hoses. This dash scale is a guide to the diameter of the hose in 1/16″ increments, as in any business.

Production Process

Tubes go through a much more rigorous manufacturing cycle, resulting in tighter tolerances on cylinder width, wall length, straightness, and roundness. Tolerance specifications that are more stringent lead to a higher level of tubing monitoring and inspection in comparison to piping products. To summarise, hoses are a very different substance than tubes and tubing, and thus the operation looks very different when a rubber or PTFE component is made similar to carbon steel or stainless steel.
