Question by: Roy C on Mar 10, 2026, 2:58 PM
runs up to 150 psi in an air brake line, that enough for standard commercial truck systems?
Answer by: Customer Support on Mar 12, 2026, 8:30 AM
For most commercial air brake applications, 150 psi is right in the working range. That's the maximum rated operating pressure for this fitting, and it's built to SAE and DOT FMVSS 571.106 specs, so it's been tested to those standards for exactly that kind of service. As long as your system stays within that ceiling, you're in good shape.
