Male threads, like a bolt, are on the exterior. Female threads, like a nut, are on the inside. Male threads are screwed into female threads. When working with hard brake lines and other stiff tubes, this might cause some confusion. At the end of these pipes is normally a male-threaded nut. This is called the end fitting. On some tubes, there is also a female thread near the end of the tube. This fits into a male thread on the other end of the connector. These are called snap-on connectors and are used for flexible hoses such as radiator water feeds.
The term "pipe fitting" is used for devices that connect two pieces of tubing together. They can be as simple as a hose clamp or as complex as a mechanical valve. Certain types of pipe fittings have male and female components that fit together to form a secure connection. For example, a union connects two sections of pipe together; each section has a threaded outer surface so that it can be joined with a third piece of pipe having the same size threads. A tee fits over a portion of a pipe and returns another branch back toward the source or another segment of the same pipe. Some types of pipe fittings, such as elbows, transfers, and T's, only cover part of the circumference of a pipe. Other types, such as caps and closures, cover the entire circumference of a pipe.
The male connection has threads on the exterior, whereas the female connection has threads on the inside. The nut and bolt is the simplest basic plumbing fitting, used to connect two lengths of tubing. A washer or O-ring seals the joint between the two tubes.
The female connection is called the outlet. It can be connected to a branch pipe or appliance line. The male connection is called the inlet. It can be connected to a main pipe or appliance line. Both connections have holes for mounting screws or bolts. The outlet also has holes for attaching flexible piping.
The term "pipe" refers to any long, slender object made of plastic or metal that carries fluid under pressure. Pipes are used for water supply lines, sewage pipes, gas pipes, and more. In plumbing, the word "pipe" also refers to the opening at the end of each tube through which you insert the other end of the tube. Pipes are usually either straight or curved. At least one side of most pipes is smooth with no openings except for the pipe itself. This is known as full coverage insulation. The coating helps prevent heat transfer through the pipe and may help prevent damage from occurring due to corrosion.
The term "tubing" refers to thick, strong wires used to carry fluids under high pressure.
Plumbing Some specialty tube fittings, such as Storz fire hose connectors, feature hermaphroditic connections, which incorporate both male and female parts in a single unit. A photo of one of these fittings may be seen under the #Genderless (hermaphroditic) connectors section of this page.
These fittings are used when you need to connect two tubes together but don't want to use a union. The term "hermaphrodite" comes from the fact that it provides access to both tubes' centers, allowing fluid to flow through them simultaneously.
They are special tools for making these connections. The word "connector" is also used for other purposes; for example, balled-steel pipe connectors are used to join sections of pipe together.
The most common hermaphrodite connection is the union. A union is a fitting with a male part that fits into a female part of another fitting. For example, a union can be made by inserting a male screw into a female nut. This connects two pieces of pipe end to end. A union can also be made by inserting a male plug into a female socket. This connects one piece of pipe to another piece of pipe or to a branch line. A union can also be made by inserting a male coupler onto a female end of a pipeline. This connects one section of pipe to another section of pipe or to a tank.
The female thread is abbreviated FHT (for "female hose thread"), while the male component is abbreviated MHT (for "male hose thread"). This fitting fits 1/2-inch, 5/8-inch, and 3/4-inch hoses. The female part has a flat end with eight threads per inch, while the male part has a dome-shaped end with three threads per inch.
This is not to be confused with mufflers which are also called "hose assemblies" or just "hoses". A muffler cuts out the high-pitched noise caused by steam escaping from pipes inside your vehicle's engine. But a hose merely channels water away from the engine unit; it can't make any sound itself.
Hoses are used for draining gas tanks, washing cars, and other tasks where you need to connect two objects for a period of time. They come in various sizes and materials depending on their use. There are copper, rubber, and plastic hoses in commercial use today. Electrician's hoses work like regular copper hoses but have metal wires inside them that conduct electricity. Heavily insulated electrician's hoses are used when you need to keep electrical devices dry during construction or renovation work.
Rubber hoses are the most common type used for watering gardens and vehicles. They are available in 2-, 4-, and 6-foot lengths.
