    That's a question you need to ask the manufacturer

    The top connector is oblong, to fit the down spout. The other end is round to connect to 4" drainage pipe.

      They are all the same size to fit inside the 4' pipe.

      This fitting is not a good fit for ADS drainage pipe. The size is too small. The gap will allow seepage and leaks that will create issues if buried. On the surface the poor fitting will leak. Not recommended.

      The item did the job. Not the highest quality but good enough. Leaving a review because home depot offers a 10% online coupon which is nice. Shipping to store worked really good and costumer service is outstanding. Thank you.

      Worked for what I needed. Wish the quality was a bit better but it got the job done.

      I got two of these to link a new drain pipe behind a retaining wall down to an existing drain. All the pieces fit together perfectly, and to 4 inch flexible pipe. The T comes with 'male' ends. I did have to make a few cuts around the perimeter edge of one side to bend it to fit inside another male pipe end of the same diameter. Small screws go in to both the pipe and the T to keep it snug. I wrapped a barrier fabric around the joint, and used zip ties to hold it all together. Looks good and works great.

      Used this to tap into an existing drain which just happened to be at exactly the correct depth for the cap to sit at ground level — just dug a 10” hole and cut out about about 4” of the existing pipe and was able to flex this on — great solution to get rid of the rainwater that accumulates in this stone path

      Used the flex tee/wye to connect 2 French drain tubes together and feed the open end of the tee/wye thru a drilled hole in my retaining wall for drainage. Flexible enough to bend in a 45 degree angle at the walls’ joint. Worked well for my project.
