If you’re installing a metal hose assembly, you should know how to measure it properly so it fits exactly how you need it. The Youtube video “Measuring Metal Hose Assembly Lengths” shows how you should do it as there are several options. Let’s find out more.
Firstly, some people measure the enitre overall assembly , which means the flexible metal hose as well as the metal fittings in the corners.
Others prefer to only measure the flexible metal hose, known as the live length, and both options are valid but are used for different aspects of the installation.
Usually, measuring the live length is used to determine whether there’s enough length to account for offsets or movements. Meanwhile, the overall length of the assembly is used to determine if the hose is going to fit where you need it.
If you’re measuring the overall length, remember to always include the end of the fitting, unless you’ve got floating flanges, in which case you have to measure to the face of the stub end. However, if you’re dealing with female GIC fittings, you don’t always measure toward the end of it.
