A Guide to Navigating DOT Fitting Compliance-old

True DOT Compliance:
Fittings Engineered for Unmatched Safety

Don’t Risk Your Reputation on Counterfeit Fittings – Trust Alkon’s Proven Compliance.

What Does DOT Compliance Mean for Fittings?

DOT compliance means adhering to rigorous safety standards established by the Department of Transportation (DOT) to ensure air brake system fittings on trucks and trailers perform safely under all conditions. Compliance involves meeting specifications set by the Federal Motor Vehicle Safety Standards (FMVSS) and Society of Automotive Engineers (SAE).

Why DOT Compliance Matters

Every year, substandard fittings contribute significantly to truck and trailer accidents:

45.5% of truck crashes involve brake-related problems.
Mechanical violations, including non-compliant fittings, are found in 55% of trucks involved in crashes.
72% of fatalities in truck crashes are occupants of other vehicles or pedestrians.

Without an approving body certifying DOT fittings, counterfeit fittings flood the market, increasing liability and safety risks. Alkon’s in-house testing ensures every fitting genuinely meets or exceeds DOT standards.
