What is Dash size?

What is 디ash size?

Simply put, Dash is a method of expressing conversion units using 16 as the denominator to indicate the size of the inside diameter of the hose.

This makes it easy to convert the inside diameter size into fractional units.

* Common sizes such as 4/16″, we also usually simplify it to 1/4″.

동시에, since the conversion relationship between dash numbers and 신장 is fixed, this means that no matter what type of hose or manufacturer, the same dash number represents the same size.

So, when you first select GEMCO or ZMTE related hose and connector products, you can refer to the 디ash numbers of other brands of products in your hands for preliminary matching, so that you can select products more quickly.

Dash size of hose

The dash size ~의 호스 is based on the value of its inside diameter (I.D.).

예를 들어, “-4” indicates a hose with an inside diameter of 4/16” or 1/4”.

Dash size of tube

In addition to hoses, we also use pipes. Unlike hoses, 그만큼 dash size ~의 tube is based on the value of its outside diameter (O.D.).
