Scope. * This standard gives the performance and requirements for new fire hose couplings and adapters with nominal sizes from 3/4 in. (19 mm) through 8 in. ( mm) and the specifications for the screw thread connections on those couplings and adapters. A Some fire-fighting organizations use small hose less than 3/4 in. (19 mm) nominal diameter fitted with garden hose couplings.
Action Coupling & Equipment, Inc. County Road P.O. Box Holmesville, Ohio Fire Hoses NH / NST vs NPSH. The most frequently used fire hoses today come with NH / NST or NPSH threads. The most common thread type in use by fire departments today is NST or National Standard Thread. It is often referred to as “fire hose thread”. NST also goes by the initials NH or National Hose. The couplings and fittings of the South Manchester Fire Department did not conform to the 'national standard' dimensions. Hydrant outlets, hydrant caps, hose couplings, nozzles and miscellaneous connections had to be altered. The hose change amounted to ab feet of hose. The hose and equipment was altered first. Well, a hose coupling is simply a connector located on the end of a hose. It couples, or connects, with a hose, tap or water source and is typically made of brass, stainless steel or aluminum. The key characteristics to understand with regard to proper thread attachment are size (3/4” to 6”), thread standard and gender.
PAR Group supply a range of fire hose couplings including BS instantaneous, Storz and Barcelona fittings. Hydrants and accessories are also available. In order to make or break the “Powerchk” coupling simply align the two lugs of the male coupling match up to the two lugs of the female coupling. When using the “Powerchk” coupling with a standard coupling, it is important to line up the higbee notches of opposing couplings. All couplings are attached to the hose jacket by an expansion. The purpose of this standard is to provide a uniform standard for safe couplings and adapters for the users of fire hose connections. Application. The requirements of this standard shall apply to the following coupling and adapters in the sizes defined in Section (1) Fire hose couplings (2) Booster hose couplings (3) Suction hose.
