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 which type of fittings are right most appropriate for your application.
- 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.)
- 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.)
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.
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.
