Barb Fittings vs. Push-Quick Fittings
Category:
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 which type of fittings are most appropriate for your application.
Ìý
- 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.)
Ìý
Ìý
- 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. are measured by tube I.D. (inner diameter), while 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 will make this easier. If you plan to set up your system and leave the hoses attached for several years or longer, might be a better option.
Durometer of Tubing
Finally, consider the durometer of your tubing. create a better seal on a slightly softer hose, while are easier to use with stiffer hose. For example, ÐdzÇweb recommends using our 85A durometer polyurethane tubing for , and 95A durometer polyurethane tubing for .
