Is It Time to Change Your Truck's Glad Hands and Hoses?


As a trucker, you know that your glad hands and hoses are two of the most important parts of your rig. These heavy duty truck parts are essential for keeping your brakes in good working order. But how do you know if your glad hands and hoses are in good condition? We've got some tips to help you out. But first, let's all get on the same page.


What Are Glad Hands? 


Glad hands are a coupling device that connects the supply and brake lines from your truck to the trailer. They're usually made of aluminum or steel and have two handles that you use to connect and disconnect. There are also glad hand seals that help to keep the air in and dirt and moisture out.



What Are Heavy Duty Hoses? 


Hoses are the air lines that connect your glad hands to the rest of your braking system. They're usually made of rubber or PVC and can be either rigid or flexible.

Glad hands and hoses are important because they help to keep your truck in good working order. If your glad hands or hoses are damaged, it can cause your brakes to fail, among other disasters. That's why it's important to inspect them regularly and replace them if they're damaged.


Why Are Glad Hands Different Colors?


You may have noticed that glad hands come in different colors. The most common colors are red and blue, but you may also see green, black, or white. The color of the glad hand corresponds to the type of hose it's connected to. The red line represents the air line for the trailer's emergency brake. The green line is the electrical line.
