All brass housings and threads – no plastic adapters
3 Flow styles, normal aerated stream, laminar non aerating stream or water saving spray
Flow rates from the U.S. max of 2.2 GPM down to 0.5 GPM sprays.
Laminar flow reduces splash and noise, great for hospitals and nursing home because no air enters the water flow
Sprays are great water savers, also have no aeration.
