This Wabco hose stud, also known as a hose barb (MPN 8931294022), is a critical component within air brake systems. It's used for secure and reliable fluid transfer in pneumatic lines. Specifically designed as a stud coupling, this component features a steel body and is compatible with a tube diameter of 11 x 3.5 and a hose nozzle diameter of 12 mm. With a maximum operating pressure of 10.0 bar and a temperature range of -40°C to +80°C, this hose nipple ensures robust performance under demanding conditions. Its M22 x 1.5 thread and 28.0 mm wrench size facilitate easy installation and maintenance. The dimensions of this component are 32 x 28 x 57 mm, and it meets OE specifications for guaranteed quality and compatibility. These little guys are all about connecting flexible air hoses to rigid air lines in your brake system. They’re basically a fitting with a barbed end – that’s where the hose grips tightly. You slide the hose over the barb, and sometimes a clamp goes over it to make absolutely sure it doesn't come loose. They come in different sizes to match your hose and air line diameters, and they’ll usually have threaded ends so you can screw them into your air tanks, reservoirs, or control valves. In your air brake system, these are critical connection points. Think of the air lines as the veins and arteries delivering the brake power. The hose barbs are where the flexible parts join the solid lines. You’ll find them connecting the air compressor to the reservoir, the reservoir to the brake chambers, and all the way around the system. They ensure a secure, airtight seal at each connection. Air brakes rely on air pressure, obviously. Any leaks, even small ones, can seriously affect your braking ability. A loose or damaged hose barb will let air escape, meaning it takes longer to build up pressure, or even worse, causes a total loss of braking power. You’ll notice if one is failing because you might get an air leak sound, or your brakes won't feel as strong as they should. They act like a shield, preventing that air from escaping and keeping your brakes working properly. You can find a good selection of hose barbs, in all the common sizes, over at Fixparts Online, if you're looking for replacements. Just make sure you get the right diameter for your hoses and lines. One size fits all: Hose Barb (MPN 8931294022) has a 12-month warranty!
