An eccentric pipe reducer is a fitting used in piping systems

  An eccentric pipe reducer is a fitting used in piping systems between two pipes of different diameters. They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side. Unlike a concentric reducer, which resembles a cone, eccentric reducers have an edge that is parallel to the connecting pipe. This parallel edge results in the two pipes having offset centre lines. The same fitting can be used in reverse as an eccentric increaser/expander.

  Horizontal liquid reducers are always eccentric, top flat (unless on control set, same as PV, TV, HV, LV), which prevents the build up of air bubbles in the system. Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer would result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump.

  The word eccentric in regards to piping is commonly mispronounced "e-sentrik" (spelled "ecentric"). This has become an industry standard and is widely taught in schools.

  Horizontal gas reducers are always eccentric, bottom flat, which allows condensed water or oil to drain at low points.
