Hose Barbs

At Process Systems, we stock high-quality hose barbs that deliver strong, leak-resistant connections for low-pressure fluid and gas applications. Whether you're working with air, water, oil, or chemicals, our hose barb fittings are built for reliability and performance in demanding environments.

Also known as barb fittings, hose barbs are designed to connect flexible hoses to threaded components. One end of the fitting features ridges (or barbs) that grip the inside of the hose, while the other end has either BSP or NPT threads to connect to a pipe, valve, or tank.

Available in a range of sizes and materials — including premium stainless steel hose barb options — our fittings are ideal for a variety of industrial, plumbing, and process applications. Our products are in stock, easy to order, and backed by decades of industry experience — so you can get what you need, when you need it. Shop online for free standard shipping Australia-wide.

Get the most out of your hose barb fittings

For optimal performance, always pair your hose barb with the right accessories. Here’s how to get the best results:

  • Use the correct clamp size — Choose a hose clamp that matches the hose diameter and tightens securely around the barb without cutting into the hose material.
  • Match the hose ID to the barb OD — The inside diameter (ID) of your hose should match the outside diameter (OD) of the barb for a snug fit.
     
  • Select the right material — Use stainless steel hose barbs in corrosive or sanitary environments. For more general use, brass may be suitable (note: not currently listed in our range).
     
  • Check compatibility — Make sure your threads (BSP or NPT) match the rest of your system’s fittings to avoid leaks or misalignment.

FAQs about our hose barbs

  • What is a hose barb?

    A hose barb is a specialised fitting used to connect a flexible hose to another component, such as a threaded pipe or valve. The barbed end is inserted into the hose, and the ridges grip the inner walls of the hose to create a tight seal. To enhance performance and prevent leaks or blow-offs, a hose clamp is often used over the hose to hold it in place.

    Key features include:

    • One end barbed to fit inside the hose
    • Threaded end in BSP or NPT for easy connection
    • Typically used with hose clamps to secure the connection
    • Suitable for air, water, oil and other fluids

  • Are hose clamps the same as hose barbs?

    No. Hose clamps and hose barbs work together but serve different functions.

    • Hose barb — The fitting that inserts into the hose, with barbs to grip the inside wall.
    • Hose clamp — A band or ring that goes around the outside of the hose, tightened to secure it to the barb.

    Using a clamp with your hose barb helps ensure a strong, leak-free connection, especially when pressure or vibration is involved.

  • Why use stainless steel hose barbs?

    Our stainless steel hose barb fittings are made from 316-grade stainless steel, offering excellent corrosion resistance, durability, and pressure handling. They're ideal for applications that involve aggressive fluids, harsh environments, or where hygiene is critical.

    Key features of our stainless steel hose barbs include:

    • Made from 316 stainless steel
    • Acid cleaned to remove swarf and contaminants
    • 150 psi pressure rating
    • Threads qualified to industry standards
    • Available in both BSP and NPT configurations

    If you’re working in food and beverage, chemical dosing, marine systems, or oil transfer lines, stainless steel fittings help ensure long-term reliability without corrosion.
