Don't be confused we also offer a Pump union that is 1 1/2" Slip X 1 1/2" Pump Wet End or 2" Slip X 2" Pump Wetend or a 2" Slip X 2 1/2" pump Wet End. If your plumbing is 1" and your Pump Wetend Thread is 1" Meaning it measures 1 7/8" Across then this part is correct. Generally This fits a Waterway Tiny Might pump both suction and pressure.
