Wabco 9522010120 Coupling Head with Integrated Filter

Description

The Wabco 9522010120 is a coupling head with an integrated filter, designed for use in trailer air brake systems. It serves as a critical component within the trailer brake controls, ensuring clean air delivery to the braking mechanisms. This coupling head is manufactured in Lithuania and features a size of 66 x 62 x 112 mm. This component meets OE specifications, providing reliable performance and durability. The integrated filter protects the air system from contaminants, extending the lifespan of downstream components and maintaining consistent braking power across a temperature range of -40°C to +80°C.

Key Features & Benefits

This part basically connects the air line from your towing vehicle to the trailer's air brake system. But it does more than just connect. The integrated filter is key—it cleans the air going into the trailer’s brakes. It removes things like water, oil, and dirt that can build up in your air lines. It also regulates the airflow, ensuring the trailer brakes respond correctly when you hit the brakes in your truck. It's a combined connector and a cleaning/regulating system. Think of it as the main link in the trailer brake system. All the braking signal, all the air pressure needed to actually stop the trailer—it all passes through this coupling head. It's right at the front of the line, where the system begins on the trailer side. It’s what translates your foot on the brake pedal into stopping power for the trailer.

Symptoms, Risks & Replacements

Well, clean, dry air is absolutely crucial for air brakes to work properly. Water and contaminants can corrode the internal parts of the trailer’s brake system – things like the air dryer, the brake chambers, even the lines themselves. That corrosion can lead to leaks, reduced braking performance, or even complete brake failure. The filter here acts like a shield, protecting the whole system. You’ll notice if this gets clogged or damaged pretty quickly – you might get a warning light in the cab, or the trailer brakes might feel weak or drag. It's a safety item, plain and simple. We carry a good selection of these at Fixparts Online, different brands and price points, so we can find one that fits your needs and budget.
