Wabco 4801030404 Cap

Description

This cap is a component used within the Air Processing Unit of Air Brake Systems. It is manufactured by Wabco under MPN 4801030404. This cap is designed to meet OE specifications, ensuring reliable performance and compatibility within the air brake system. Its dimensions are 20 x 20 x 29 mm, contributing to its precise fit and function.

Key Features & Benefits

This cap seals off the air processing unit itself. That unit does a few really important things – it filters the air going into your braking system, regulates the air pressure, and removes moisture. The cap is simply the final seal, keeping all that clean, dry air inside where it needs to be and keeping dirt and water out. It's a surprisingly simple part, but crucial. Think of the air processing unit as the heart of your air brake system. It’s providing the air that actually stops the vehicle. This cap is the final layer of protection for that heart, preventing contamination. It keeps everything working smoothly and consistently. It's typically located right on top of the unit, so it's fairly exposed to the elements.

Symptoms, Risks & Replacements

If this cap fails, or cracks, you'll start getting unfiltered air and moisture into the system. That can lead to corrosion, and eventually, brake failure. You’ll notice if it’s leaking – likely from visible moisture around the unit, or a drop in air pressure if you're checking your gauges. It’s a small, inexpensive part to replace, and honestly, doing it proactively is way cheaper and safer than dealing with a brake issue. We’ve got a good selection of these at Fixparts Online, and it’s one of those things that’s pretty straightforward for a DIYer to swap out.
