What Is a Standard Garden Hose Fitting?

Standard garden hose fittings connect your hose to a faucet or spigot, available in various shapes and sizes made of either plastic or brass – brass being preferred due to its greater watertightness and durability.

Measure hose fitting diameter using either a tape measure or by taking measurements from its inside (if female thread) or outside (if male thread). This will enable you to select an ideal size fitting that works with both your hose and faucet.

National Pipe Taper Thread (NPT)

There are various fittings you can attach to the end of a garden or household hose, including nozzles, connectors, and couplings. Some are made from plastic while others from brass or metal. Brass fittings tend to provide stronger watertight seals while remaining more cost effective; plastic alternatives often fail due to being less durable and costly overall.

When selecting a hose fitting, be sure to match its thread size with that of your outdoor faucet or spigot. Otherwise, using one with incompatible thread size could result in it not connecting at all or leaking; additionally, using one of an incorrect diameter could lower water pressure significantly.

Hose thread sizes are often indicated on product packaging or labels; sometimes, this size will also be printed directly onto both female and male parts of a hose fitting. If you are uncertain as to your thread size, use a tape measure to take measurements inside of female fittings’ inside opening and external threads (male fittings).

GHT and NPT garden hose connectors are among the most widely-used fittings, used to connect or repair garden hoses, nozzles, and accessories. These fittings feature both garden-hose thread connections on one end as well as standard plumbing pipe or hose thread threading on the other end for convenient connection or repair of garden hoses, nozzles, and accessories. Although they appear similar, these connections should never be confused as GHT threads are parallel while NPT ones have tapered threads; you can easily distinguish the two by their markings at either end. GHT to NPT adapters and connectors, available as male or female adapters, are among the most frequently used garden hose connectors. They can be used to join two lengths of garden hose end-to-end or extend the reach of nozzles or sprayers attached with attachments requiring GHT or NPT connections; additionally there are many nozzles, garden accessories, and couplings with both types of connections.


Material choice of garden hose will impact its durability, water capacity and suitability for your environment. Rubber garden hoses tend to be durable but come with higher prices and can be cumbersome to transport; while hybrid rubber/vinyl garden hoses with reinforced strengthening mesh layers between their layers offer an intermediate option that’s less likely to kink under higher water pressure levels than standard rubber ones.

Couplings are fittings that connect a hose to a spigot or nozzle, and come in various materials including plastic, metal and brass. Brass fittings tend to be more costly but considered superior when it comes to performance and longevity; plastic fittings tend to break more easily than their metal counterparts.

When purchasing a garden hose, it’s essential that it is “drinking water safe,” meaning it won’t release chemicals into the water supply. This is especially important if using your hose to wash your car or irrigate your garden – to be certain, check that its permanent label indicates this fact.

As with selecting any garden hose, its diameter should also be taken into consideration when purchasing one. Larger diameter hoses will hold more water but may not fit as snugly with faucets or fittings, so before purchasing any fittings it would be beneficial to take a measurement using either wooden dowels or drill bits in order to get an approximate measurement.

Finally, it is crucial that you know which thread size your garden hose uses so as to find fittings compatible with it and other equipment. Garden hoses typically feature 11.5 NH threading which ensures it can connect securely to other pieces of equipment without loosening or coming undone from its connection point at the tap.

Thread Size

The diameter of the thread on a garden hose is essential as it determines if and how well it fits onto an attachment, such as faucet or other. Furthermore, its flow determines how much water can pass through it at what pressure. Therefore it is imperative to take an accurate measure of your current thread size prior to purchasing replacement fittings or new hoses; you can use a tape measure or wooden dowels for this task before searching out one with matching diameter fittings that will fit perfectly.

Brass, aluminum, and plastic hose fittings are commonly available for most outdoor faucets and spigots, with brass being more durable than plastic in terms of longevity and corrosivity resistance. Brass can even be used with saltwater solutions and chemical solutions without fear of disintegration compared to plastic versions – though more costly overall.

Most hose thread fittings are tailored to work with a particular type of hose or spigot, often designated with letters such as M, F or FG to indicate which kind they will connect to and have descriptive markings that outline what size thread they accept; some even feature male pipe threads on one end and female hose threads on the other!

Some hose thread fittings feature an internal valve that shuts off water flow when disconnected from a spigot or hose, providing an easy way to reduce waste and make attaching and detaching appliances simpler. While these fittings tend to cost more, they can prove invaluable and convenient.

Garden hose thread adapters come in many varieties, from transition, coupling, and swivel fittings to transition, coupling, and swivel fittings. Each has their own specific purpose. Most are constructed from brass or an alloy composed of both brass and plastic for corrosion resistance and longer use; chrome-plating will provide added durability and enhance appearance; these will cost slightly more than unplated brass but last longer and look nicer overall. Also available are threaded couplings which allow multiple hoses to connect without needing to take apart their respective original coupling – ideal if multiple hoses need to share your property!


Installing garden hose fittings requires making sure that you have the appropriate size connections, as connecting a hose to an incorrect fitting can result in water leaks and pressure losses. To make sure that you have the appropriate connection, the easiest way is to measure the inside diameter of the hose opening with either a tape measure (although an accurate reading may be difficult as its tape will press against its opening) or wooden dowels or metal drill bits – these methods may not provide as accurate of an estimation as a tape measure does).

Once you have taken measurements, the next step will be selecting an appropriate fitting. There are numerous types of hose fittings on the market and each serves a distinct purpose – some common examples being:

Hose-to-hose adapters join two lengths of hose together. They’re often used to extend or repair damaged hoses and feature GHT (garden hose thread) connections on both ends – which may either be male or female threading.

GHT-to-NPT adapters allow a garden hose to connect directly to a pipe or accessory such as a spray gun or sprinkler, using national pipe thread connections on both ends, which may either be male or female depending on your preferences.

Flow control valves regulate the water flowing through a hose by turning their handle, with some models featuring an accidental opening lock to protect themselves from accidentally being opened by accident. Hose nozzles attach directly to the end of a hose to create spray or stream effects; typically constructed of brass or stainless steel and available in multiple sizes.

Quick-disconnect fittings make it simple to unplug a hose from a faucet without twisting and turning the handle, and can even be used to connect additional accessories like nozzles to hose ends. Regular inspection of these fittings for signs of wear is important and replacement should be undertaken as necessary.
