Wabco 4324306214 Piston

Description

This piston is a critical component within the air dryer system of air brake systems. It functions to compress air, enabling efficient braking performance in heavy-duty vehicles and trailers. Manufactured by Wabco with MPN 4324306214, this piston is designed to OE specification, ensuring reliable operation and longevity. Measuring 35 x 12 x 35 mm, this component delivers precise air compression and contributes to a responsive and safe braking system.

Key Features & Benefits

This little guy actually does a pretty simple job, but it’s key to keeping your air brake system working right. Basically, it moves back and forth inside the air dryer cylinder. That movement compresses the air, pushing moisture out and then expelling it through the drain valve. It’s kind of like squeezing water out of a sponge – the piston does the squeezing. It also helps regulate the airflow through the system. It lives inside the air dryer, which is part of your air brake system. The air dryer’s job is to clean and dry the compressed air before it gets to your brakes. Think of it like a filter and a water separator all in one. The piston is a core component that makes that drying happen. Without it moving properly, the air stays full of water and oil, and that messes everything up. You'll find it connected to the connecting rod, and that's what translates the air compressor's motion into the piston’s back – and – forth action.

Symptoms, Risks & Replacements

Moisture in your air brakes is a really big deal. It can corrode brake lines, freeze up in cold weather, and generally just reduce the stopping power. This piston helps get rid of that moisture before it causes trouble. It acts like a shield, protecting the rest of your air brake system from damage. You’ll notice if this piston starts to fail because you’ll likely get a build – up of water in the air tanks, and that’ll trigger your brake warning light. You can find a replacement piston – we stock them at Fixparts Online, along with the whole air dryer if you need it – and replacing it is a pretty straightforward job for a mechanic. Ignoring a bad piston can lead to seriously unsafe braking, so it’s definitely something you want to address when you notice a problem.
