Piusi F19473000 2-1/2" x 5 Buttress Thread to 2" Drum Bung Hole Adapter

    The Piusi p/n F19473000 is a 2-1/2" x 5 buttress thread  to 2" drum bung hole adapter fitting. This allows Piusi DEF pumps (which have 2-1/" x 5 buttress threads) to be used with regular 55 gallon drums, which have a 2" bung hole. This design allows Piusi stainless steel rotary drum pumps F00332A30 to be used with drums of anti-freeze or windshield washer fluid.
