Product review (4 stars): Fits perfectly, secures drain hose and installs easily.
I purchased this Hose Grip Coupling as I didn't have a good way to secure my washing machine drain hose to my drain pipe in the laundry room.  The coupler fit perfectly over the 1.5 inch pvc drain in my laundry room, and the 1 inch drain hose from my washing machine fit perfectly into the coupler.  I used a shot of WD40 to make the drain hose slide into the coupler easily, which resulted in a nice tight fit.  I would recommend this product.
