Barb Fittings vs. Push-Quick Fittings

Should you use barb fittings or push-quick fittings for your application? If you're having trouble deciding, you're not alone. Here are a few things to consider when trying to decide what type are fittings are right for your application.

 

Push-Quick
  • Easier to disconnect
  • Better suited for applications which require frequent connecting/ disconnecting of hoses
  • Usually provide higher flows than equivalent barb fittings
  • Work best with stiffer tubing
  • Measured based on tubing outer diameter (O.D.)

 


 

Hose Barb
  • Tend to create a better seal
  • More difficult to disconnect
  • Better suited for "low-leak" environments/applications
  • Usually lower cost than equivalent push-quick fittings
  • Work best with softer tubing
  • Measured based on tubing inside diameter (I.D.)

 

Tubing Size

The first thing you should consider is your tubing size. Barb fittings are measured by tube I.D. (inner diameter), while push-quick fittings are measured by tube O.D. (outer diameter). If you already have tubing that you are using, be sure to match the tubing to the appropriate fitting for a tight seal.

Frequency

Next, consider how frequently you will be connecting hoses to the fittings. If you plan to disconnect and reconnect hoses frequently, then push-quick fittings will make this easier. If you plan to set up your system and leave the hoses attached for several years or longer, barb fittings might be a better option.

Durometer of Tubing

Finally, consider the durometer of your tubing. Barb fittings create a better seal on a slightly softer hose, while push-quick fittings are easier to use with stiffer hose. For example, Clippard recommends using our 85A durometer polyurethane tubing for barb fittings, and 95A durometer polyurethane tubing for push-quick fittings.
