Common fittings for both piping and plumbing
While there are hundreds of specialized fittings manufactured, some fittings are used widely in piping and plumbing systems.
Elbow A pipe fitting installed between two lengths of pipe or tube allowing a change of direction, usually 90° or 45°. The ends may be machined for butt welding, threaded (usually female), or socketed, etc. When the two ends differ in size, it is called a reducing or reducer elbow. Most elbows are available in short radius or long radius of types. The short radius elbows have a center to end distance equal to the NPS in inches, while the long radius is 1.5 times the NPS in inches. Short elbows are universally available; long elbows are readily available in Acrylonitrile butadiene styrene (ABS, plastic), PVC for DWV, sewage and central vacuums, and copper for 1950s to 1960s houses with copper drains.
Street elbow A variant of the elbow, typically of male to female connections; see Street elbow.
Tee A tee is used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well. Tee-fittings are also an integral part of the computer-enthusiast level watercooling solutions found in many modern enthusiast PCs. The fitting is one of the three main components of a T-Line, alongside an end-cap or fillport and a length of tubing. They are plumbed into the system, with the perpendicular barb (and its attached stretch of tubing leading to a fillport or a cap).
Cross A cross has one inlet and three outlets, or vice versa. Crosses are common in fire sprinkler systems, but not in plumbing due to their extra cost as compared to using two tees. The three outlets should be named in order; left, middle , right. For example 15-22-15
Coupling A coupling connects two pipes to each other. If the material and size of the pipe are not the same, the fitting may be called a 'reducing coupling' or reducer, or an adapter. The term 'expander' is not used for a coupler that increases pipe size; instead 'reducer' is used. Couplings for copper pipe are available either with or without a stop. The stop is in the center of the coupling and is useful for ensuring that the coupling is centered between the two pipes being connected. The disadvantage of a stopped coupling is that in some repair situations it may be necessary to slide the coupling completely on to one pipe and then slide it back when the pipes being joined are in position. The type of coupling that doesn't have a stop is referred to as a repair coupling. Repair couplings are available in longer than standard lengths to facilitate the repair of a short length of pipe.
Cap A type of pipe fitting, often liquid or gas tight, which covers the end of a pipe. A cap has a similar function to a plug. In plumbing systems that use threads the cap has female threads.
Plug A plug closes off the end of a pipe. It is similar to a cap but it fits inside the fitting it is mated to. In a threaded iron pipe plumbing system, plugs have male threads.
Union A union is similar to a coupling, except it is designed to allow quick and convenient disconnection of pipes for maintenance or fixture replacement. While a coupling would require either solvent welding or being able to rotate all the pipes adjacent as with a threaded coupling, a union provides a simple nut transition, allowing easy release at any time. In addition to a standard union, there exist Dielectric Unions which are used to separate dissimilar metals (such as copper and galvanized steel) to avoid the damaging effects of electrolysis. When two dissimilar metals are placed in an acidic solution (most tap water is mildly acidic), they will form a battery and generate a voltage. If the two metals touch and conduct, the flow of current from one metal to the other will cause a movement of ions from one to the other, dissolving one metal and depositing on the other. A dielectric union breaks the electrical current with a plastic liner between two halves of the union.
Nipple Short stub of pipe, usually threaded iron, brass or copper; occasionally just bare copper. A nipple is defined as being a short stub of pipe which has two male ends.
