The Wabco PRO2000220 Trailer Coupling Head is a critical component within a trailer's air brake system, specifically designed for trailer brake controls. It's used to connect the air brake lines between the tractor and trailer, enabling effective brake signal transmission. This coupling head features a robust design with a M16 x 1.5 port thread, ensuring a secure and leak-free connection. Measuring 65 x 50 x 95 mm, this yellow, free flow device operates effectively within a temperature range of -40°C to +80°C and supports a maximum operating pressure of 10.0 bar. Its AM specification and without filter design contribute to reliable performance and ease of maintenance. This part basically connects the air lines from your truck to the trailer’s air brake system. It’s where the air pressure goes from your towing vehicle to activate the trailer's brakes. It handles the supply line, the emergency line, and the signal line – everything needed to tell the trailer brakes what to do. It also has a manual release lever, so you can manually disconnect the trailer's brakes if needed, like when you’re doing some servicing. Think of it as the central nervous system between your truck and the trailer's braking. Without it, your truck can't ‘talk’ to the trailer brakes. It’s a crucial part of the air brake system, and it sits right at the front of the trailer, where you hook up. It's what physically connects the two systems and allows for safe, coordinated braking. Honestly, this is a safety item through and through. If this coupling head fails, your trailer brakes might not work properly, or at all. You’ll notice if it’s going bad – you might get a loss of air pressure to the trailer, or the brakes could feel sluggish. It acts like a shield, protecting the system and ensuring the trailer brakes respond when you hit the pedal in your truck. A faulty coupling head is a serious problem, so it’s really important to keep it in good working order. You can find replacements pretty easily, even online at places like Fixparts Online, but don’t skimp on this one – a good quality part is worth it for the peace of mind. Quality you can count on: Trailer Coupling Head (MPN PRO2000220) comes with a 12-month warranty!
