Wabco 9522010140 Coupling Head with Integrated Filter

Description

The Wabco 9522010140 Coupling Head with Integrated Filter is a critical component in trailer air brake systems, specifically within the trailer brake controls. This coupling head connects the air lines between the tractor and trailer, enabling effective brake signal transmission. It features an integrated filter to remove contaminants from the air supply, protecting the braking system from damage and ensuring optimal performance. Measuring 66 x 83 x 114 mm, this component is designed to OE specification and operates efficiently within a temperature range of -40°C to +80°C. The inclusion of a filter and test connection capability contributes to improved system reliability and ease of maintenance.

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.
