When assembling a hose, it is important to note when the “overall length” (OAL) is critical. In most industrial applications (such as water or general purpose) the OAL is not critical, but in many hydraulic applications the OAL can be critical due to space restrictions. The OAL of a hose assembly can be determined by measuring a hose assembly from end-to-end. The following illustrates how to correctly measure specific end configurations (hose should NOT be taut when installed):

• Male threaded ends are measured from the end of their threads (refer to figure AC.1)
• Female threaded ends and Flanged ends are measured from their sealing surface (refer to figure AC.2 & AC.3)
• Angled ends are measured from the center of their sealing surface (refer to figure AC.3 & AC.4)
