When calculating the overall length (OAL) of a hose assembly that has a pipe thread as one or both end connection(s), consideration must be given to thread engagement. For example, using the chart below, a hose assembly with a 1″ male pipe on one end would have 0.66″ added to the OAL to compensate for the length of thread that will be engaged during installation.
