got a tight spot on my machine, how tight can i bend this H430 hose without kinkin it
Answer by: Customer Support on Mar 26, 2026, 7:25 AM
Minimum bend radius on the Weatherhead H430 100R12 in dash size -12 is 4.72 inches. Staying at or above that bend radius helps keep the hose from being overstressed in a tight routing.

Four spiral wire reinforcement sounds heavy duty, but how many cycles can this hose actually hold up through before it starts breaking down?
Answer by: Customer Support on Dec 9, 2025, 7:19 PM
Half a million impulse cycles is the rated life on this one. That puts it well above what most standard two-wire hoses can handle, and it's part of why the four-spiral construction gets used in applications where the pressure is constantly cycling rather than just holding steady. For heavy industrial hydraulic service, that kind of cycle life means you're not swapping hoses out nearly as often.
