Wabco 9522010020 Air Filter Coupling

Description

The Wabco 9522010020 is an Air Filter Coupling, a critical component within trailer air brake systems. It's designed for use in trailer applications, ensuring clean, filtered air reaches the braking components. This coupling features a M16 x 1.5 port thread, and operates effectively within a temperature range of -40°C to +80°C, up to a maximum operating pressure of 8.5 bar. Its OE specification and integrated filter contribute to system reliability and longevity by preventing contamination and ensuring optimal braking performance.

Key Features & Benefits

This little piece connects the air filter to the rest of your air brake system. Think of it as a junction box—it’s where the clean air coming from the filter joins the air lines that go to things like your brake chambers and other pneumatic components. It physically makes that secure connection, and more importantly, it ensures that connection is airtight. It’s not just a simple pipe fitting; it's designed to handle the specific air pressure we’re talking about in a brake system and keep everything sealed. It's a crucial part of your trailer’s air brake system, specifically how clean, dry air gets delivered. The air compressor makes the air, the filter cleans it, and this coupling is the doorway for that cleaned air to actually get to the brakes. Without it functioning properly, you won’t have reliable braking. It’s tucked away in the system, so it doesn't do anything you see directly, but everything relies on it working.

Symptoms, Risks & Replacements

This is a safety item, plain and simple. If the coupling fails—if it cracks, leaks, or isn't properly sealed—you'll lose air pressure in your system. You’ll notice if this starts happening; your gauges will drop, and your brakes will become less effective. It acts like a shield, protecting the integrity of the whole air system. A small leak here can lead to bigger problems and seriously compromise your ability to stop. They don't always fail dramatically—sometimes it’s a slow leak that’s hard to pinpoint. We carry these at Fixparts Online, and it’s a relatively inexpensive part to replace, so it’s really smart to address it as preventative maintenance before it becomes a real issue.
