What tubing sizes do these fit?

They work with 1/2", 5/8", and 0.7" drip tubing. 

Are they easy to install?

Yes, just push tubing onto the barbed ends for a quick, secure fit. 
 

Do they create a leak proof seal?

Yes. The high quality barbs ensure a tight, leak proof connection.

Are they durable outdoors?

They’re made from UV and chemical resistant materials for long life above or below ground.

What pressure do they work with?

Recommended for 0–50 PSI systems.

What are these couplings typically used for?

• Repairing damaged tubing segments
• Extending existing drip lines
• Creating custom drip layouts
• Adding supplemental watering areas

Can they be buried underground?

Yes. These fittings may be used above or below ground without compromising performance. 

How can I fix a small drip at one of the connections?

Ensure the tubing is fully seated onto the barb. Drips are usually caused by incomplete insertion or tubing that’s cut unevenly. 
 

How does the Rain Bird Insertion Tool help with installation?

The Rain Bird 1/2" Barbed Fitting Insertion Tool reduces installation effort by 50%, firmly holds the fitting for leverage, and includes a flaring feature that widens tubing for smoother insertion; making installs faster, easier, and more comfortable on your hands.
