NST also goes by the initials NH or National Hose. It can even be referred to as NHT or National Hose Thread. But NST or NH is more common these days. NH = NST GHT: Threads are garden hose thread (GHT), which is 3/4″ diameter parallel (non-tapered) thread with a pitch of 11.5 threads per inch (TPI), which require gaskets or O-rings to seal when connected NPT: Threads are National Pipe Thread and is an American standard thread, NPT has tapered threads, so GHT and NPT threads are not compatible with each other Please noted: 1.The dimensions marked in the picture are measured manually and may be slightly different from the actual size. 2.Thread Size is a nominal pipe size and it does not represent the actual diameter. Please look the size chart for the specific thread diameter. ProductDescription1 : These Metal Magery Breakable Caps for Fire department Connections are cast aluminum. Each set includes two caps and 4 eyelets with nuts for 21/2” swivels. The caps have been molded with “scored” tabs for easy removal with a hydrant wrench or other similar tool. Metal Breakable caps provide inexpensive protection against the introduction of foreign material into the swivels but allow for quick access when a hose connection is necessary. ProductDescription2 : Installation: Remove the caps from their packaging. Hold the breakable cap to the opening of swivel. Align the breakable tans with the pin lugs on the swivel. Once aligned, insert the threaded end of one eyelet through the hole in the tab of the cap then slide the eyelet over the pin lug. Once the eyelet is in place, carefully thread the included 1/4-20 finished hexnut on to the threaded end of the eyelet until snug. Caution: Do not overtighten. The tabs of the break caps are designed to break with minimal force.
