Used to convert 1.5" threaded pumps to 2" plumbing - (using a 2" pump union not included) and this 1.5" - 2" threaded adaptor (1.5" female thread / 2" male thread)
Screw the adaptor onto the suction/discharge of the pump to effectively change its thread size from 1.5" to 2" so the 2" pump union can thread on.
