Metal Barbed Hose Fittings with Kink Absorber for Air and Water
Eliminate sharp bends at the end of your air and water hose—these fittings have a built-in kink absorber. The kink absorber reduces strain on your line, preventing damage. To install, slide the kink absorber onto your hose then push the barbed end of the fitting into the hose. The fitting's barbed end also has threads that connect the kink absorber, hose, and fitting all together. As you thread on the kink absorber to the fitting, it compresses against the hose, forming a strong seal.
Fittings that swivel until tightened rotate, so you don’t need to twist your hose during installation.

Retracting D.O.T. Air Hose
- Temperature Range: -40° to 200° F
- Material: Nylon Plastic
- Color: Blue or Red
Safely deliver compressed air to brakes in semitrucks, trailers, and other vehicles with this D.O.T. certified hose. It meets performance and labeling standards for use in vehicle brake systems. Made of flexible nylon, it will bounce back to its coiled form even after extended for long periods. It’s firm enough to hold itself off the ground without support from hangers, so it’s often stretched between a tractor and a trailer. For a secure connection, the fittings have thread sealant already applied. Each fitting also has a spring guard to prevent the hose from kinking. The fittings are brass and the spring guards are galvanized steel to resist rusting.
To prevent connecting the wrong hose, this hose matches the D.O.T's color coding. Blue hose is for service brakes. Red hose is for emergency brakes.
