Air brake hoses are a critical component of the braking system in commercial vehicles, such as trucks and buses. Here are some of the key features and characteristics of air brake hoses:
Material: Air brake hoses are typically made of synthetic rubber, which is durable and resistant to weather and abrasion. They may also have a reinforcing layer of braided or spiraled synthetic fibers for added strength.
Size: Air brake hoses come in various sizes, ranging from 1/4 inch to 1 inch in diameter. The size of the hose is usually determined by the type and size of the vehicle, as well as the length of the hose needed to connect the brake components.
Length: Air brake hoses are available in various lengths, ranging from a few inches to several feet. The length of the hose depends on the distance between the brake components that need to be connected.
Pressure rating: Air brake hoses are designed to withstand high pressure, typically up to 200 psi. The pressure rating of the hose is usually marked on the hose itself.
Temperature range: Air brake hoses are designed to work in a wide range of temperatures, typically from -40°C to 100°C. This makes them suitable for use in a variety of weather conditions.
Fittings: Air brake hoses have specialized fittings that are designed to connect to the other components in the braking system, such as the brake chambers, air compressor, and air dryer. The fittings are usually made of brass or steel for durability and corrosion resistance.
Color coding: Air brake hoses are color-coded to help ensure that the right hoses are used for the right application. For example, the hose that connects the air compressor to the air dryer is usually blue, while the hose that connects the air dryer to the brake chambers is usually red. This helps prevent confusion and potential brake system failures.
