Frequently Asked Questions (FAQs)

1. What connects to a barb fitting?

A barb fitting is designed to connect to a tube or hose. The ridges or bumps on the fitting grip the inside diameter of the tube, creating a seal and securing the connection. As the tube is installed on the fitting, it expands over the barb, ensuring a tight grip and seal.

2. Do you need a hose clamp on a barbed fitting?

In most cases, a hose clamp is not necessary when using a barbed fitting. The hose barb is designed to hold onto the tubing, particularly soft-side tubing like clear PVC, on its own. However, in some instances, a hose clamp may be used to provide additional stability.

3. What is the difference between push to connect and barbed fittings?

The main difference between push-to-connect and barbed fittings is the way they seal and the space they require. Push-to-connect fittings seal on the outside diameter of the tubing and require more space as the fitting body encompasses the tubing. Barbed fittings, on the other hand, seal on the inside diameter of the tubing and do not need to be as large.

4. How can I stop a barbed coupler from leaking?

If a barbed coupler is leaking, you can try gently tugging it to snug it up against the tubing wall. In some cases, this can fix the leak. If not, you may need to remove the coupler and insert a goof plug into the hole or punch a new hole nearby to address the issue.

5. Do barbed fittings work with PEX?

Yes, barbed fittings are compatible with PEX (cross-linked polyethylene) tubing. PEX barb fittings can be used for applications such as potable water distribution and hydronic heating. They can be used with either the stainless steel clamp system or the copper crimp ring system.

6. What is the biggest advantage of push to connect fittings?

The primary advantage of push-to-connect fittings is their ability to quickly and reliably make connections. Whether it's for a new installation or an emergency repair, push-to-connect fittings save time and effort, which translates to cost savings.
