Fittings and connectors are crucial plumbing components that attach one end of a pipe to another in order to lengthen the flow direction in a plumbing system. They are used to combine, reduce, or divert the flow of liquid or gas. The type of connector that should be used in a system depends on several factors that include: the type of fluid line, maximum pressure, and type of fluid medium. The main types of fittings
and connectors include the threaded
connectors where both the connector and the end of the pipe are threaded. Threaded connectors are recommended when dealing with low-pressure fluid power systems. Another common type of connector is the flange model. In this category, flanges are attached to the piping through welding, tapered threads, or rolling and bending. They are suitable for gasket material between the flanges. Other types of fittings and connectors include adapters, elbows
, coupling, union, tee, nipple, and reducers.
