How does the minimum bend radius of a MIL-H-8794-5 hydraulic hose compare for a flexing installation vs a non-flexing installation at maximum pressure?

The minimum bend radius for a MIL-H-8794-5 hydraulic hose is greater for a flexing installation compared to a non-flexing installation at maximum pressure. This is due to the additional stresses and potential for fatigue that occur during flexing operations. When a hose is subjected to repeated bending, such as in a flexing installation, the material experiences different mechanical forces that can lead to failure if the bend radius is too small.

In contrast, a non-flexing installation does not subject the hose to the same dynamic movements and stresses, allowing for a smaller bend radius without risking damage or premature wear. Therefore, the design specifications account for these differences, ensuring greater durability in applications where the hose must flex frequently. This is an important consideration for maintaining the integrity and longevity of hydraulic systems, ensuring they operate safely and effectively under full pressure.
