This part is a 7 3/8" ID O-Ring only for a WUA500 or SWIM56-15 5 Horse Power 56 Frame Pump Wet End fits Power-Rite Guangdong LX Brand SWIM56-15 Pump Motors only. These pumps usually have the part number Swim56-15 or WUA500 on the label.
NOTE: This O-Ring does not fit WUA500B Wet Ends which would be 2 1/2" x 2".. If you have that type of Wet End search for a wua400 o-ring..
It is about 9" across the face of the pump, it measures about 11" from the bottom to the top of the pressure side of the volute, it also measures 6 3/8" from the back to front edge. The Suction and Pressure side thread fittings are called 2 1/2" x 2 1/2" but measure 3 5/8" from the edge of the thread to the edge of the thread.
NOTE: This Wet End looks a lot like an Aqua-Flo XP3 and a Waterway Viper Wet End but they do not interchange!
