Features of D.O.T. Push to Connect Air Fittings

What Is a D.O.T. Fittings?

D.O.T. fittings, also called Department of Transportation fittings, are specialized connections used in air brake systems of large, heavy vehicles such as trucks, buses, and trains. These fittings play a crucial role in the safety and control of these vehicles, ensuring that the compressed air brake system operates efficiently, especially critical in emergencies. The U.S. government mandates that these fittings meet specific standards to ensure reliability and safety on the road.

D.O.T. air brake fittings offer a robust connection that can withstand the constant vibration of a moving vehicle. Additionally, the installation time for push-to-connect fittings is significantly less than compression fittings, leading to increased efficiency in assembly processes.

Compression Fittings vs. D.O.T. Push to Connect Air Fittings

There are primarily two types of D.O.T. fittings used in air brake systems: compression and push-to-connect fittings.

  • Push-to-connect fittings are favored for their quick and tool-free assembly. They are available in various materials which are lighter and can contribute to improved fuel efficiency and payload capacity.
  • Compression fittings are available in more sizes. However, it also requires the use of tools to install.
