AQP Engine & Air Brake Blue Hose, FMVSS106, 0.88 Inch ID, Up to 400.00 PSI

Air applications max out at 250 degrees Fahrenheit. While the hose generally handles fluids up to 300 degrees, you need to keep compressed air under that 250-degree limit and below 250 PSI for safe operation.

For air service specifically, the limit is 250 PSI, not the full 400. The 400 PSI maximum operating pressure applies to other compatible fluids like fuel, lubricating oils, and coolants. So if you're running this in an air brake system, keep your operating pressure under that 250 PSI threshold. Temperature follows the same split logic too. Air should stay at or below 250 degrees F, while the overall hose rating goes up to 300 degrees F.

For routing, the minimum bend radius is 3.5 inches. Keeping bends at or above that radius helps it stay flexible without collapsing or kinking.
