Wabco 8931040532 Bulkhead

Description

This Wabco bulkhead, MPN 8931040532, is a critical component within air brake systems. It's used to create a secure and reliable connection for air lines, ensuring optimal braking performance in heavy-duty vehicles. Measuring 15 x 17 x 38 mm, this component meets OE specifications for seamless integration and durability. The M12 x 1.5 threads on both ends ensure a tight, leak-proof seal, contributing to the overall safety and efficiency of the braking system. This bulkhead is designed for long-lasting performance and reliability under demanding conditions.

Key Features & Benefits

These fittings basically connect air lines running through a metal panel – that panel could be the frame rail, a chassis crossmember, even the body of the vehicle. They create a sealed connection where the line passes through, preventing air leaks. They’re designed to hold pressure, obviously, and have threads on both sides – one part screws onto the fitting itself, and the other side connects to the air line coming from your compressor or other components. Think of it as a doorway for your air lines. Your air brake system relies on consistent pressure throughout, and these bulkheads are where those lines need to pass through structural parts of the vehicle to get where they need to go. You’ll find them connecting things like the air supply line to the brake chambers, or linking the compressor to the reservoirs. They are a crucial part of keeping everything connected and airtight.

Symptoms, Risks & Replacements

Air leaks in a brake system are a big deal, naturally. Even a small leak can reduce braking power, and that’s something you absolutely want to avoid. A bulkhead acts like a shield, making sure that pressurized air stays inside the lines where it belongs. You’ll notice if one starts failing because you’ll likely hear a hissing sound, or maybe even see moisture around the fitting. They're generally pretty reliable, but over time, corrosion or vibration can cause them to loosen or crack. If you’re doing any work on your air lines, it's a good idea to inspect these. You can find a good selection of them at places like Fixparts Online, and they're usually pretty straightforward to replace.
