A 37° flare type end fitting for flexible hose The AN thread (also A-N ) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN.
Piping or tubing is usually inserted into fittings to make connections. Connectors are assigned a gender, abbreviated M or F. An example of this is a "3 ⁄ 4-inch female adapter NPT", which would have a corresponding male connection of the same size and thread standard (in this case also NPT).
A hose coupling is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel , brass , stainless steel , aluminium or plastic .
A push-in compression coupling and tee.. Push-to-pull, push-to-connect, push-in, push-fit, or instant fittings are a type of easily removed compression fitting or quick connect fitting that allows an air (or water) line to be attached, nominally without the use of tools (a tool is still usually required for cutting tubing to length and removal).
In the modern standard metric version, it is simply a size number, where listed diameter size is the major outer diameter of the external thread. For a taper thread, it is the diameter at the "gauge length" (plus/minus one thread pitch) from the small end of the thread.

A coiled garden hose. A garden hose, hosepipe, or simply hose is a flexible tube used to convey water.

Hoses are usually attached to a hose spigot or tap.
