The purpose of this document is to provide standards for application to the threaded parts of hose couplings, valves, nozzles, and all other fittings used in direct connection with hose intended for domestic, industrial, and general service in normal sizes of 1/2, 5/8, 3/4, 1, 1 1/4, 1 1/2, 2, 2 1/2, 3, 3 1/2, and 4 in. The normal sequence of connections, in relation to the direction of flow, is from an externally threaded nipple into an internally threaded coupling. The basic dimensions are given in Table 1 while complete detailed dimensions and thread form are given in Tables 2 and 3.
