Wabco 8971216004 Diaphragm

Description

This Diaphragm is a critical component within air brake systems, specifically used in air dryers to regulate air pressure and ensure optimal braking performance. Manufactured by Wabco with MPN 8971216004, this diaphragm maintains system efficiency by responding to pressure changes. Its dimensions are 5 x 70 x 56 mm. This component is designed to meet OE specifications, offering reliable performance and durability for commercial vehicle applications.

Key Features & Benefits

This little rubber piece—it looks kinda like a flexible disc—basically regulates the air pressure within the air dryer. It moves back and forth, opening and closing valves inside the dryer. This movement controls how much air gets through and helps remove moisture, oil, and other nasty stuff from the compressed air system. It's a key part of keeping everything running smoothly. Think of your air brake system as needing really clean, dry air to work right. This diaphragm is right at the front line of that process. It's inside the air dryer, which is sort of like the lungs of the system. It’s what breathes in the compressed air, filters it, and then sends clean air onwards to your brakes, suspension, and other air – powered components. It’s not directly in the brakes themselves, but it’s vital to the whole process.

Symptoms, Risks & Replacements

Well, moisture and contaminants in your air lines can cause all sorts of trouble. Corrosion, frozen lines in winter, and reduced braking performance are just a few. This diaphragm helps prevent all that. If it fails, you’ll likely notice reduced brake performance, longer stopping distances, or even the air brake warning light coming on. It acts like a shield, protecting the rest of the air system from damage. They do wear out over time, especially with road grime and temperature swings. You can often find replacements like this one at places like Fixparts Online, and it's generally a pretty straightforward repair, but it's important to get it done if you suspect it's failing. Ignoring it can lead to bigger, and more expensive, problems down the road.
