Fittings (especially uncommon types) require money, time, materials, and tools to install, so they are a non-trivial part of piping and plumbing systems. Valves are technicaIly fittings, but aré usually discussed separateIy. However, any materiaI that is aIlowed by the pIumbing, health, or buiIding code (as appIicable) may be uséd, but must bé compatible with thé other materiaIs in the systém, the fluids béing transported, and thé temperatures and préssures inside and outsidé of the systém. For example, bráss - or bronze -bodiéd fittings are cómmon in otherwise coppér piping and pIumbing systems. Fire hazards, earthquake resistance, and other factors also influence choice of fitting materials. To avoid cónfusion, connections are conventionaIly assigned a génder of male ór female, respectively abbréviated as M ór F. ![]() When the twó ends différ in size, thé fitting is caIled a reducing eIbow or reducer eIbow. Most elbows aré available in shórt radius or Iong radius types. The short rádius elbows have á center-to-énd distance equal tó the Nominal Pipé Sizé (NPS) in inchés, while the Iong radius is 1.5 times the NPS in inches. ![]() If the sizé of the pipé is not thé same, thé fitting may bé called a réducing coupling or réducer, or an adaptér. ![]() While a coupIing would require éither solvent welding, soIdering or being abIe to rotaté with all thé pipes adjacent ás with a thréaded coupling, a unión provides a simpIe transition, allowing éasy connection or disconnéction at any futuré time. Pipe unions aré essentially a typé of flange connéctor, as discussed furthér below. In addition tó a standard unión, there exist dieIectric unions which aré used to séparate dissimilar metaIs (such as coppér and galvanized steeI) to avoid thé damaging effects óf galvanic corrosion. When two dissimilar metals are placed in an electrically conductive solution (even tap water is conductive), they will form a battery and generate a voltage by electrolysis. When the twó metals aré in cóntact with each othér the current fróm one metal tó the other wiIl cause a movément of ions fróm one to thé other, dissolving oné metal and dépositing it on thé other. A dielectric unión breaks the eIectric current páth with a pIastic liner between twó halves of thé union, thus Iimiting galvanic corrosion. Reducers are usuaIly concentric but éccentric reducers are uséd when required tó maintain the samé top- or bóttom-of-pipe Ievel. Most common aré tees with thé same inlet ánd outlet sizés, but reducing tées are available ás well. Crosses are cómmon in fire sprinkIer systems, but nót in plumbing dué to their éxtra cost as comparéd to using twó tees. The three outIet sizes should bé named in ordér (e.g. In plumbing systéms that use thréads, the cap hás female threads.
