K1178A Adjustable Aerator Assembly
First time using this part on my Dishmaster. Have well water, time will tell how this filter works for us.
Although aerators have a built in filtering device, they are not meant to be depended upon as the primary filter. Especially whenever the water source has a persistent problem with debris, there should be a primary filter placed where the water enters the home.
My order delivered promptly and was an easy repair
