What is the working pressure of the trailer air brake coiled hose?

The working pressure range for a trailer air brake coiled hose can vary based on factors such as the hose's design, materials, construction, and intended use. Air brake systems in vehicles, including trailers, operate under regulated pressure levels to ensure safe and reliable braking performance. Here are some general considerations for the working pressure range of trailer air brake coiled hoses:

Standard Working Pressure Range:

Trailer air brake coiled hoses are typically designed to withstand working pressures in the range of 150 psi (10.3 bar) to 200 psi (13.8 bar). This range covers the typical pressure levels used in air brake systems.

Pressure Ratings: The actual pressure rating of a specific trailer air brake coiled hose will depend on the hose's construction and the materials used. It's important to check the manufacturer's specifications and guidelines for the hose to determine its exact pressure rating.

Compliance with Regulations: Trailer air brake coiled hoses must meet regulatory requirements and industry standards to ensure their safety and reliability. Regulatory bodies such as the U.S. Department of Transportation (DOT) in the United States and relevant authorities in other regions may set standards for air brake system components, including hoses.

Quality and Design: High-quality trailer air brake coiled hoses are designed and constructed to withstand the pressure levels specified for air brake systems. These hoses are typically reinforced with materials such as synthetic textiles or steel wire to provide the necessary strength.

Safety Factors: When designing and selecting air brake hoses, safety factors are considered to ensure that the hoses can handle pressure spikes or other stressors that might occur during braking operations.

Maintenance and Inspection: Regularly inspect and maintain trailer air brake coiled hoses to ensure they are in good condition. Look for signs of wear, damage, or deterioration that could compromise their performance and safety.
