Universal Fit Drain Pipe Hose Silicone Plug, Washing Machine Drain Hose Sealing Plug Kitchen Pipe Sewer Seal Ring Laundry Room Bathroom Bathtub, Black White Blue 3 Pack

I used this in my kitchen sink to support my washer drain hose in. Had to cut some of the rubber to make it fit better but it worked.

We were suffering the bad smell in our laundry room for long time. Tried cleaning washing machine time to time, pouring chemicals to pipe etc, but not very helpful. This small piece works! It perfectly match with the washing machine pipe and stops the smell 99% I will say!

Needs to be bigger

You just use one of these adapters no screws to tighten. I had a leak under the washer and this connector took care of what had been coming out of the overflow pipe.

Would not seal my standard 2" drain as advertised. Had to lube up second one and slide it up over first one. This did seal the drain.
