Barb Styles Hose barbs are available in many different styles across pages 58-96. Each style is driven by the experience and specific requirements considered by the barb designer. Hose barbs are typically described by the nominal inner diameter (ID) of the tubing they are intended to be inserted into. This description should not be interpreted as a guarantee of performance of the barbed connection with any specific sized tubing. There are no consensus standards for barb dimensions to fit tubing IDs. In many cases, a barb may be used with different ID tubing than described.
