Wabco 8939203512 Fitting

Description

This Wabco 8939203512 fitting is a crucial component within air brake systems, designed to connect tubing and maintain airtight seals for optimal braking performance. It's used in the connections of air lines and is an OE specification component. This fitting measures 20 x 50 x 22 mm and features ports to accommodate tubing with diameters of 12 x 1 mm, 10 mm, and 14.6 mm. The design ensures reliable connections, minimizes air loss, and contributes to the overall safety and efficiency of the air brake system.

Key Features & Benefits

These fittings connect the air lines in your air brake system. Seems simple, right? But it’s a bit more than just a connector. They have to create an airtight seal, handle the pressure from the air compressor – sometimes quite a bit of pressure – and withstand a lot of vibration from the road. Different fittings will do slightly different things – some are straight connectors, some are elbows to change direction, some have ports for gauges or controls. Basically, they manage the flow of compressed air throughout the system. In your truck or trailer, the air brake system is obviously critical. These fittings are a small part of that, but a vital one. They’re the links in the chain, ensuring the pressurized air gets to the brake chambers at each wheel. Without that air pressure delivered reliably, you won’t have effective braking. Think of them as little gatekeepers making sure everything stays sealed and the air flows where it needs to.

Symptoms, Risks & Replacements

It’s honestly pretty straightforward. A leaky fitting – even a tiny one – can cause a loss of air pressure, and that impacts your stopping power. You’ll notice if you have a major leak, of course – a hissing sound, maybe even the brake warning light coming on. But small leaks can be harder to detect, and they gradually reduce your braking efficiency. They can also cause corrosion within the system over time. It’s a safety thing, plain and simple. A good fitting acts like a shield, keeping moisture and dirt out, and air in when it’s supposed to be.
