Wabco 8934010020 90 Degree Push-In Coupling

Description

The Wabco 8934010020 is a 90-degree push-in coupling used within air brake systems to connect tubing and provide a secure, leak-free connection. This component is designed for use in commercial vehicles and trailers. The coupling's OE specification ensures compatibility and reliable performance within existing air brake infrastructure. Its dimensions are 20 x 42 x 29 mm, providing a compact solution for tight spaces and efficient airflow.

Key Features & Benefits

This coupling’s job is pretty straightforward – it connects sections of air line together, creating a sealed connection. The 90 – degree bend is key because it lets you run air lines around corners or in tight spaces without kinking or stressing the line. It basically "pushes in" onto the air line, and those little barbs inside grip the line to hold it secure. It's a simple idea, but it needs to be solid. In your air brake system, these couplings are everywhere. They connect the compressor to the reservoir, the reservoir to the brake chambers, and all the various control valves in between. Think of it like plumbing for your brakes. Air is the fluid, and these couplings are the pipes and fittings that keep everything connected. Because it’s a 90 – degree fitting, you’ll often find them where lines need to turn sharply—near the axles is a common place.

Symptoms, Risks & Replacements

Well, obviously, your air brakes are critical. If this coupling fails—if it cracks, gets loose, or leaks—you lose air pressure. You’ll notice if you have a leak, usually as a hissing sound or a drop in your gauge readings while driving. Even a small leak can gradually reduce your braking power, and that’s a serious safety issue. They’re designed to withstand a lot of vibration and pressure, but rubber and plastic do degrade over time. Fortunately, they’re relatively inexpensive to replace. You can find a good selection, including these 90 – degree versions, over at Fixparts Online—it’s a convenient place to get air brake parts. Replacing a failing coupling is a small job that can prevent a major headache, and keep you safe on the road.
