A neatly coiled garden hose A garden hose, hosepipe, or simply hose is a flexible tube used to convey water. There are a number of common attachments available for the end of the hose, such as sprayers and sprinklers ( which are used to concentrate water at one point or to spread it over a large area ). Hoses are usually attached to a hose spigot or tap.

The term `` hose '' is also used for other types of flexible, water - carrying tubes such as those used by fire departments. Description Garden hoses are typically made of extruded synthetic rubber or soft plastic, often reinforced with an internal web of fibers. As a result of these materials, garden hoses are flexible and their smooth exterior facilitates pulling them past trees, posts and other obstacles. Garden hoses are also generally tough enough to survive scraping on rocks and being stepped on without damage or leaking. Each male end of a typical garden hose can mate with the female connector on another, which allows multiple garden hoses to be linked end - to - end to increase their overall length. Small rubber or plastic washers ( often confusingly called `` hose washers '' ) are used in female ends to prevent leakage, because the threads are not tapered and are not used to create a seal. Sometimes the gaskets stiffen, disintegrate, or fall out of older hoses, which results in pressurized leakage spraying from the hose ; simply replacing the washer insert often fixes the problem. Most garden hoses are not rated for use with hot water, and their packaging will often specify whether or not this is the case. Leaving non-reinforced hoses in the hot sun while pressurized can cause them to burst. Hoses used to carry potable water are typically made of NSF International - listed polymers tested and shown not to leach harmful materials into the drinking water, such as the plasticizers ( phthalates ) used in polyvinyl chloride ( PVC, or vinyl ) hoses. Usage Sprayer pistol uses a quick - connect fitting, visible just beyond the sprayer grip As implied by the name, garden hoses are commonly used to transport water for gardening, lawn care, and other landscaping purposes. They are also used for outdoor cleaning of items such as vehicles, equipment, building exteriors, and animals. NSF - approved hoses may be used for connecting drinkable water to recreational vehicles and trailers. Whenever a flexible hose is connected to a drinkable water supply, the spigot or tap should be fitted with an approved backflow prevention device, to prevent contaminated water from being siphoned back, in the event of a pressure drop. Many water suppliers require this, and plumbing code may legally require permanently installed backflow preventers. Porous or perforated hoses Special hoses designed to leak throughout their length are sometimes used to gently distribute water on a lawn or garden. These hoses either have many small holes drilled or punched in them, or are deliberately formulated of a porous material, such as sintered rubber particles. These `` soaker hoses '' are a simple, low - cost, crude type of drip irrigation system. Expandable hoses These differ from traditional hoses in that the inner membrane expands when filled with water, much like a balloon. An outer cover protects the delicate expandable membrane from punctures. Such hoses `` grow '' when pressurized, and shrink back down when the pressure is released, allowing for easier storage. Standards and connectors Brass hose spigot with standard threads ( internal, not visible ) and GHT ( visible ) threads Garden hoses connect using a male / female thread connection. Spigots typically have male connectors, and one end of a hose has a captive nut which fits the threads. The technical term for this arrangement is a `` hose union ''. The thread standard for garden hose connectors in the United States, its territories, and Canada is known colloquially as `` garden hose thread '' ( GHT ), but its official designation is NHR ( NH stands for `` National Hose '' ; 3⁄4 - 11.5 NHR is for thin - walled couplers typically found on hoses, and 3⁄4 - 11.5 NH is for full form threads as produced by cutting or rolling material such as the brass pipe or valve fittings ). The standard was defined by NFPA 1963, `` Standard for Fire Hose Connections '', then later by ANSI - ASME B1. 20.7, which is ⁄ inch ( 19 mm ) diameter straight ( non-tapered ) thread with a pitch of 11.5 threads per inch ( TPI ). The female thread is abbreviated FHT, and the male part ( MHT ) has an outer diameter of 1 ⁄ inches ( 27 mm ). This fitting is used with ⁄ - inch, ⁄ - inch, and ⁄ - inch hoses. In other countries, a British Standard Pipe ( BSP ) thread is used, which is ⁄ inch and 14 TPI ( male part outside diameter is 26.441 mm or 1.04 in ). The GHT and BSP standards are not compatible, and attempting to connect a GHT hose to a BSP fitting, or vice versa, will damage the threads. Various adaptors made of metal or plastic are available to interconnect GHT, BSP, NPT, hose barb, and quick connect fittings. Quick connectors Starting in the 1990s, the use of quick - connector systems has become more popular. These are fittings that screw into the common hose connectors, allowing hoses and accessories to be easily connected together using a snap - fit system. The style manufactured by Gardena is common, imitated by and compatible with many other manufacturers. The connectors may optionally include an internal valve that is only opened by connecting the fitting, so that disconnecting a hose using this adaptor causes the water flow to stop. This greatly eases common tasks by allowing specialized sprayers to be interchanged without requiring two trips back to the spigot for each change. Health risks from aerosols In 2014, it was reported that use of common garden hoses in combination with spray nozzles may generate aerosols containing droplets smaller than 10 μm, which can be inhaled by nearby people. Water stagnating in a hose between uses, especially when warmed by the sun, can host the growth and interaction of Legionella and free - living amoebae ( FLA ) as biofilms on the inner surface of the hose. Clinical cases of Legionnaires ' disease or Pontiac fever have been found to be associated with inhalation of garden hose aerosols containing Legionella bacteria. The report provided measured microbial densities resulting from controlled hose conditions in order to quantify the human health risks. The densities of Legionella spp. identified in two types of hoses were found to be similar to those reported during legionellosis outbreaks from other causes. It was proposed that the risk could be mitigated by draining hoses after use. History This section needs expansion. You can help by adding to it. ( August 2017 ) In the United States, the first garden hose spray nozzle, and thus possibly the first US threaded garden hose coupler, was made prior to 1890 by the W.D. Allen Mfg. Co. of Chicago, Illinois.
