Understanding the Importance of DOT Approval

Selecting DOT-approved tubing is paramount for ensuring the highest levels of safety and performance. These tubes are rigorously tested to meet stringent regulations set by the National Highway Traffic Safety Administration (NHTSA), covering a wide array of performance aspects beyond mere pressure resistance.

Key Considerations for Selecting DOT-Approved Tubing.

  • Compliance and Safety: Always opt for hoses with the "DOT" marking on both the Tubing layline and fittings, as this certification is your assurance of meeting safety and legal requirements for use on public roads. 
  • Material and Construction: Choose tubing that meets the operational needs of your environment. Our DOT-approved tubing is designed with materials that ensure durability, flexibility, and resistance to harsh conditions.
  • Application Requirements: Consider the specific needs of your application, including temperature ranges, exposure to oils and chemicals, and the physical demands of your system.
  • Length and Diameter: Proper sizing is crucial to avoid pressure losses and ensure system efficiency. Our DOT-approved products are designed for optimal performance, even when custom-cut to specific lengths.
