What is the recommended amount of slack needed when installing a flexible hose assembly?

The recommended amount of slack needed when installing a flexible hose assembly is 5-8%. This range ensures that there is sufficient flexibility in the hose to accommodate movement and vibration, which can occur in operational environments. Adequate slack prevents excessive strain on the hose, which could lead to premature wear, kinking, or potential failure of the assembly.

Choosing a percentage that is too low may not provide enough leeway for the hose to flex properly during operation, while a higher percentage could result in unnecessary slack, increasing the risk of the hose coming into contact with other components or leading to a more complex installation process. Therefore, a slack of 5-8% strikes a balance between flexibility and stability, ensuring that the hose assembly performs effectively without compromising safety or function.
