Auto brake hose has strict standard to ensure safety and performance. These standards are put in place to maintain the integrity of the braking system and enhance overall road safety. In the United States, the primary regulatory authority for air brake hose is the Department of Transportation (DOT). The primary standards and specs for air brake hoses in the U.S. include:
DOT FMVSS 106
The Federal Motor Vehicle Safety Standard (FMVSS) No. 106 is issued by the National Highway Traffic Safety Administration (NHTSA). It outlines the standard for air brake hoses used in vehicles. Besides, this standard sets requirements for construction, strength, and durability. What’s more, it includes the specs for burst strength, temp resistance and more.
Auto Brake Hose SAE J1402
The Society of Automotive Engineers (SAE) developed the SAE J1402 standard. It provides detailed specs for air brake hose. While those include physical properties, performance and tests. Many air brake hoses meet or exceed the SAE J1402 standard. But in fact, besides SAE J1402, there is SAE J1401 standard.
DOT Markings
Air brake hoses must be labeled with specific DOT markings. While that indicates compliance with the relevant regulations. These markings include info about the manufacturer, the hose’s compliance with DOT specs and other relevant details.
Color Coding
Auto brake hoses must adhere to color-coding standards to indicate their specific function within the air brake system. Common color codes include blue, red and yellow. Blue is for service brake hose. While red is for emergency and parking brake hose. Then yellow is for trailer supply hose.
Length and Size
Regulations also specify the allowable lengths and sizes of air brake hoses. While this is to ensure proper fit and function in heavy vehicle.
It’s to note that standards for air brake hoses may vary in different countries and regions. Therefore, it’s essential to adhere to the specific standards.
