hose gonna hold up running coolant and fuel lines on a diesel engine? temps get pretty nasty under the hood
Answer by: Customer Support on Jun 22, 2025, 7:44 AM
Rated for service up to 300°F, this hose handles coolant and fuel applications in engine compartments without issue. The AQP elastomer tube paired with polyester inner braid and single wire reinforcement gives it solid resistance to the kind of heat and pressure cycling you'd see on a working diesel. Just keep in mind the air brake side tops out at 250°F rather than the full 300, so if you're routing air lines near a high-heat zone, factor that in.

What kind of stuff can I run through this hose? I'm using it in my garage.
Answer by: Customer Support on Aug 16, 2025, 6:47 AM
This AQP hose handles air, gasoline, fuel, lubricating oils, and coolants. Just make sure to review the guidelines for selection, installation, and maintenance.

got a tight little spot to snake this through, how sharp can i bend it without kinkin it
Answer by: Customer Support on Nov 16, 2025, 6:37 AM
For routing, the minimum bend radius on this hose is 1.75 inches. Staying at or above that bend radius helps it flex without kinking, and the hose OD is 0.77 inches if you are checking clearance.
Question by: Melvin T on Aug 26, 2025, 12:34 PM
What kind of fluids can I run through this hose, besides air?
Answer by: Customer Support on Aug 28, 2025, 7:11 AM
This hose is good for gasoline, fuel, lubricating oils, and coolants.
Question by: Glen G on Jan 9, 2026, 8:46 AM
hose rated for air brake lines on a diesel truck, or is it just for engine stuff?
Answer by: Customer Support on Jan 11, 2026, 8:11 AM
Air brake applications are explicitly covered by this hose. It carries the FMVSS106 rating, which is the federal standard specifically required for air brake hose used on motor vehicles. The one thing worth noting is the temperature limit for air service: while the hose handles fluids up to 300 degrees F, compressed air use is capped at 250 degrees F. For most diesel truck air brake setups that falls well within normal operating range.
