Description

The Wabco 8938312120 is a fitting module used within air brake systems. This component facilitates secure connections between air lines, ensuring the reliable operation of braking mechanisms in commercial vehicles. It's characterized by dimensions of 30 x 88 x 51 mm, and is manufactured to OE specification, providing a precise fit and consistent performance. This fitting features connections for 12 x 1.5 mm and 8 x 1.0 mm tubing, with M22 x 1.5 threading, and wrench sizes of 22 mm for both connections. Its design ensures durability and leak-proof operation, contributing to enhanced safety and system efficiency.

Key Features & Benefits

This little part is basically a connection point, a central hub if you will, for multiple air lines in your brake system. It takes several individual lines and combines them into a single, secure connection to the air reservoir or other components. It manages the airflow, ensuring everything’s properly connected and sealed. Sometimes these have check valves built in, too, so air only flows in one direction. Think of your air brake system like a network of roads. The Fitting Module is like a major intersection or roundabout. It directs the compressed air where it needs to go – to your brakes, to the air dryer, and so on. It’s a critical piece within that whole system, allowing everything to work together. It's usually located somewhere along the main air lines, often near the air dryer or reservoir.

Symptoms, Risks & Replacements

It’s really important because any leak or failure here compromises the entire braking system. Air brakes rely on consistent pressure, and this module ensures that pressure isn't lost through faulty connections. You’ll notice if this part fails—you might get a warning light, a drop in air pressure, or even a noticeable difference in how the brakes respond. It acts like a shield against air leaks, keeping everything safe and reliable. You can find a good selection of these, including replacements, over at Fixparts Online, but the important thing is to make sure you get the right one for your vehicle’s setup. A failed fitting module can mean a major safety issue, so it’s something you want to address promptly.
