Oatey 33400 Mechanical Test Plug, 1-1/2 in, 5 Psi Back, Plastic, Red 110 Deg F, Multicolor, 1.5 Inch

I put a new sink in when remolding the kitchen. The pipe for the garbage disposal snapped off in the two way pipe. I was going to bore it out but was scared it would become a real nightmare and shatter being old. Found this great little Oatey gripper and worked out perfect.

I bought this to temporarily seal a drain my basement sink that I will be installing. It works great, no more smell or noise when someone uses the water.

Fits perfectly and very easy and quick to install. Works perfectly and no leaks.

to bad it does not show up prominently in amazon search. I was lucky to find it after wading through 50 other paid paid promotions of inferior products.
