Product review (5 stars): About Half the Big Box Price
I needed a M-M coupler from my install and a couple more pieces for the dryer.  The pieces for the dryer were unrelated to this part - the dryer spec. sheet was incorrect.  This is about HALF PRICE of the big box stores and it appears at your door.  I did not use the sealent or leak detector packets as I had nicer versions already but they were included.
