Product review (5 stars): Unsrew the ring on the fossett befor you buy an adapter to see if it fits
Great little washer connects to my kitchen fosset I had to unScrew the ring on the  fosset then it fitted.. I was soo bummed out because I thought I was gonna have to buy a new adapter Im so happy it fits. Only thing I wish the drawing hose was longer to fit in the sink but I tier to the water hose to drain and thats been workin for me
