Wabco 4325110020 Inline Filter

Description

This Wabco Line Filter, MPN 4325110020, is a critical component within air brake systems, ensuring clean and dry compressed air reaches the braking components. It is used in heavy-duty vehicles and trailers to remove contaminants, moisture, and oil from the air supply. Measuring 110 x 178 x 110 mm, this filter maintains optimal brake performance and extends the life of the air system by protecting sensitive components. The filter operates efficiently up to 16.0 bar and within a temperature range of -40°C to +80°C, featuring M22 x 1.5 JED-152 connections on both ports. It's OE specification and bidirectional flow capability ensures compatibility and reliable operation.

Key Features & Benefits

This filter basically cleans the compressed air that goes to your brakes. It takes out things like water, oil, and dirt – anything that shouldn’t be going into that system. It’s a pretty simple device, but it does a crucial job. Most will have a replaceable filter element inside, sometimes a spin – on type like an oil filter, sometimes a cartridge you swap out. They also usually include a drain valve so you can get rid of any accumulated moisture. Think of it as a gatekeeper for your air brakes. The air compressor creates the air pressure, but before that air actually powers the brakes, it needs to be clean. The inline filter sits in the air line, between the compressor and the brake components, doing just that. It's part of a larger system, of course, with things like air dryers, but this is a key first line of defense.

Symptoms, Risks & Replacements

Well, air brakes rely on clean, dry air. Water and contaminants can cause corrosion inside the system, freeze up in cold weather, or just gunk things up. That can lead to brake failure, and nobody wants that! It acts like a shield protecting everything downstream. You’ll notice if this filter gets clogged – brakes might be slow to engage, you’ll get reduced braking power, or you might even get warning lights. They’re relatively inexpensive to replace, and doing it regularly is way cheaper than fixing major brake damage. You can find a good selection of them at places like Fixparts Online, and they usually list what vehicles each one fits. It’s a small part, but it makes a big difference to safety.
