Questions & Answers

On the BrassCraft website it shows these hoses being all black. On the HD website it shows the crimp is stainless steel. Which is it?

Answer This Question

We have recently made the switch to an all-black connector including the ferrule (crimp). It was released a few months ago, so it may take time for the product to hit the store shelves.

    Black Toilet Supply Hose
    Received the toilet supply hose in perfect condition. After draining toilet tank and removing the older supply hose I easily installed this new black hose. Easily hand mounted to the bottom of the toilet tank and then hand tightened the smaller end to the shut off valve. I further tightened the smaller end using a simple 5/8 in open end wrench until it was snug but not over tight. It looks great an the black color matches the black accents in our bathroom. Would recommend this product.

    toilet supply hose
    I got these to replace the supply line on my toilet that was 45 years old. I chose black because I thought they would be less notable and I was right. All supply lines are relatively the same so there is not much to say/ this one installed easily with only a wrench required. The tank side came off and on easily by hand. the supply line side needed a wrench to remove and tighten because of the compression fitting. I looks beautiful!!

    Standard size Toilet supply line but is BLACK!
    These 12" Flexable black braided toilet Supply lines are FANTASTIC! You get all the quality of the Stainless Steel with a decorative black coating. The 3/8" Compression end fits to your Angle Stop as it should, with ease. The other end 7/8" is what connects to your toilet. It has a rubber cone washer built in and only needs to be finger snug. They do the job and look good doing it.
