Hose barb fittings are a type of push-on hose fitting. They are used most often in applications with soft tubing, such as clear PVC, but can also be used with metal and other types of hose. The fittings have a barb on them that grips the tube, holding it in place. They are available in a variety of materials, including brass and steel.Hoses come in a variety of sizes and temperatures, as well as pressures and chemicals. Typically, the hoses have an internal braid or mesh that gives them strength when they’re pushed into a fitting.
The hose expands slightly to get over the barbs on the fitting, and then it tightens its grip on the barbed fitting, which holds it in place. The hose and the barbed fitting are designed to work together to create a leak-free connection.What if the hose is too big or too small for the hose barb?Generally, larger-diameter hoses are easier to assemble because they have more material to expand over the hose barbs. The smallest-diameter hoses are harder to assemble because they have less material to expand over the barbs on the fitting.
What if the hose has been damaged?If the hose has been damaged, it will probably need to be replaced. It can also be difficult to remove the hose from a hose barb because the barb design doesn’t allow it to easily be removed.
