Wabco 8938009740 Straight Bulkhead Coupling

Description

The Wabco 8938009740 Straight Bulkhead Coupling is a critical component within air brake systems, designed to connect air lines securely. This coupling is typically used in heavy-duty vehicles and trailers where a robust and leak-proof connection is required. Measuring 22 x 24 x 42 mm, this straight male stud coupling features a M16 x 1.5 thread and is compatible with 12 mm tube diameter. Engineered to OE specification, this coupling ensures reliable performance and contributes to the overall safety and efficiency of the braking system by providing a durable and secure connection point.

Key Features & Benefits

This little piece basically joins two sections of air brake line together, but it does it where the line needs to pass through something – like the frame of the vehicle, a chassis component, or a floor. Think of it as a connector that allows the air line to go straight through a barrier. It has threads on both ends to screw into the existing air lines and tighten everything up. It's part of your truck or trailer’s air brake system, specifically how the compressed air gets from the compressor to the brakes themselves. It’s not glamorous, it’s not something you see, but it’s a critical link. It allows the air lines to continue uninterrupted, even when they need to go through a solid object.

Symptoms, Risks & Replacements

This might seem like a small part, but a leak here can be a big deal. The air brake system relies on consistent pressure, and even a tiny leak can reduce braking effectiveness. This coupling, when properly installed and sealed, acts like a shield, preventing air from escaping. You’ll notice if one of these starts to fail because you might hear a hissing sound, or your brakes just won’t feel as strong. They're pretty durable, but vibrations and corrosion can eventually wear them down. If you’re doing brake work, it’s a good idea to check these couplings for cracks or damage. You can find these pretty easily, places like Fixparts Online carry a good selection. It’s a relatively inexpensive part to replace, and it can save you a lot of headaches down the road.
