Fluidmaster B1F20 Faucet Connector, Braided Stainless Steel - 3/8 Female Compression Thread x 1/2 F.I.P. Thread, 20-Inch Length

Our kitchen sink blasted out water on the cold side, but the pressure was very low on the hot side. The hot water for our other sinks came out fine... it was just the kitchen sink that had the low pressure on the hot side. I took the faucet apart several times, changed various parts, and flushed everything, but that didn't do anything to fix the problem. It can be somewhat maddening waiting for the hot water to finally get to the faucet just to wash your hands or the dishes. I thought it may have been the supply valve not opening fully, but I didn't really feel comfortable trying to change the supply valves. Instead, I wanted to try replacing the supply hoses first to see if that helped... and, what do you know... after I changed the hoses, the water blasted out of the hot and the cold equally. I took a look at the hot and cold supply hoses I removed. I pulled the hoses straight, held them up to a light source, and tried to look through them. The old, cold supply hose allowed some light to come through, but no light shined through the old, hot supply hose. I cut a coat hanger, straightened it, and shoved it through the old hot supply line, but nothing came through. Even after doing that, I could not see any light shining through the hose, so it was probably degraded so much from the years of hot water rushing through it that the rubber part was collapsing onto itself. The old supply hoses were probably a different brand... they were braided stainless steel on the outside and had black rubber on the inside, but that black rubber easily left residue on anything rubbed against it. The old supply hoses were over 15 years old, so it wasn't a big shock to see that they finally had to be changed. The Fluidmaster hoses are nice and appear to be good quality. The reviews on here were the main reason I bought these specific hoses on Amazon instead of some other brand at a local home improvement store. The packaging the hoses were shipped in was somewhat ok. The hoses were looped, wrapped in bubble wrap, and put in a padded envelope. I would have preferred that they were shipped completely straight in a box. The hoses arrived fine... the hoses and hose ends were undamaged. I bought the same length as the supply hoses that were on the sink, but the supply hoses (the old ones and the replacements) had to be looped, which I'm not sure is such a good thing... but I'm not sure using a shorter length would've worked out so well because the supply valves were coming up straight from the basement but went out at a 90 degree angle instead of continuing on straight. These are compression hoses, so you do not use tape or pipe dope when attaching them. I bought a basin wrench just to remove the old hoses and to put on the new hoses... that basin wrench was quite heavy (over 2-1/2 pounds) to use at such an awkward angle, but they worked. If I removed the drain pipes and laid underneath the sink, it would've been easier to use the basin wrench (maybe no so easy on my back)... but, I didn't want to take more things apart and have to clean up the water from the drain pipes. I tightened the hoses hand-tight and then about a half turn more (like the instructions that come with the supply hoses say to do) with the wrench/basin wrench. I thought I had it tight enough and checked back hours (and days) later to see if there were any leaks. I basically wiped everything dry with a tissue and then took strips of tissue and touched them against the hose fittings. I did see an extremely tiny leak on the cold side at the faucet/supply hose connection, so I gave it another quarter-turn/half-turn... that fixed the problem. Make sure not to confuse water condensation on the pipes for a leak. Changing the hoses myself was far better than shelling out over $100 for some plumber to do this, and who knows what crappy brand of supply hoses he would have put on... forget that. Plus, I have a basin wrench in case I needed to do this again for another sink or change out the faucet.

If you’re going to replace exiting water lines use these! They are the best! A little high in price but quality costs!

No issues with this brand of hose. It is a hose, to connect the valve to the faucet inlet. Fairly simple, no frayed braids. This was also cheaper than the big box DIY stores.

I had a leaky kitchen faucet and connector supply hose that needed to be changed. I purchased this Fluidmaster hose based on the construction and the positive reviews. I connected it to new faucet and I haven't encountered any leaks so far. Minus 1 ⭐ because it arrived smashed.

Nice water faucet hose, good quality hose and easy to install.

Strong, flexible high quality faucet connector hose. Don’t waste time with other brands. I’m a DIY’er but do a lot of plumbing projects.

I was afraid I was going to need to purchase an entirely new sink to fix a persistent leak, but all it required is new hoses. Very easy to install with just an adjustable wrench. One tip: Add a couple drops of silicone lubricant to the gaskets and threads, then hand tighten plus about a half turn with a wrench. That is enough to get a good seal and prevent leaks. Don't overtighten or you'll just end up tearing the gasket.

They look very good but I had to return them due to the wrong connections, other than that the replacements are not a problem.

Perfect length to replace original plastic cord in RV.
