Hose Barb Fittings


A hose barb is a type of coupling inserted into hoses and tubing with ridges that grip the tube for a secure connection.

Barbed fittings are constructed with ridges that grip the inside of a tube without damaging it. Hose barbs include elbow and straight fittings with male and female-threaded ends in brass and plastic materials. Brass barbs work best for hot-water applications, and plastic barbs work best with cold water. Metal fittings are not always stronger than plastic fittings. They perform better under high pressure, but plastic fittings are just as secure and cost less.

Plastic barbs, including nylon, polypropylene, polyethylene, and PVC fittings, are used for home and commercial plumbing. Types of barb fittings range from garden hose adapters to fittings for fountain beverage machines. An adapter is a type of barb fitting with a barb and threaded connector.

Knowing whether a type of fitting and tube work well together is key to establishing a strong connection.

Factors to consider when looking for a hose barb fitting

  • • Inside diameter of tube
  • • Intended use
  • • Tube material

Flexibility determines the strength of the connection. Hose barbs perform best with softer tubing. If a barb’s ridges are too sharp for the tubing material, pulling the fitting in and out could damage the tubing.

When to use a clamp with a hose barb

Sometimes, a clamp helps strengthen the grip of the barb. Usually, a barb is secure enough without a clamp; however, if your tubing is extremely flexible or the barb has been removed and reused multiple times, then a clamp may be necessary.
