Fluidmaster 4F16UCSR Universal CLICK SEAL Faucet Connector, Braided Stainless Steel - 3/8-Inch, 7/16-Inch, 1/2-Inch Compression, or 1/2-Inch F.I.P. Thread x 1/2-Inch F.I.P. Thread, 16-Inch Length

These were perfect to connect my water line from the main line to the faucet. Screwing it on was really easy and I didn't have any leaks, only took the first try to get it on.

These are by far the easiest faucet connectors I have ever used. I have been replacing sink faucet connectors in our house for years and won’t buy any other kind now.

I bought this knowing that I would need the 3/8" compression end and 1/2" FIP. This was cheaper than buying the other ones so I decided to give it a try. I think it works well and I like that it really is steel, unlike many today that have a plastic braid to them. I'm not so sure I like the click seal part of it. It works very much like your drill with the number settings for pressure/strength of drilling. Once it gets to their specified setting (which you can't change) of tightness you can't keep tightening. I guess if you tend to over tighten things then this might be good for you. I wanted to give it a slight bit more of a turn than they have it set to but it works okay and is not leaking. This could be very handy to keep in a handyman garage collection because of its universality. The compression end may be too big and bulky/in the way for some applications because it is 1/2" sized but you put in the right ring to make it smaller on the inner diameter.

2 huge advantages for less-than-handy guy performing DIY plumbing:1) no need to worry about what is the existing supply line size thus buying the right connector size; down side is you waste 2 adaptors2) no need to guess when you have tightened enough or if you have overtightened it, all accomplished without toolsJust make sure you measure the distance between end of supply line and end of faucet intake. Mine are between 11" and 12". So the 16" is perfect.

I purchased this hose because I mistakenly believed that all Fluidmaster hoses were manufactured in Mexico. I don’t care about quality as much as I care about supporting North American manufacturing.

This faucet connector is really helpful if you are working in a tight place when trying to connect the new faucet to the water supply. You can use your fingers to tighten the connection to the faucet and know it is done right when you hear the click Don't have to try to get tools into the space under the faucet. The connection to the water supply works like any other connector but does give you options if you don't have a standard size water shut off.

I tried to use this for my kitchen faucet. Even after connecting and tightening until the 'click' it still had a slight leak. When I finally caved and brought a professional plumber out to my house he saw we were trying to use these. He said he's seen others try these before and they almost never work as promised. I'm glad he was able to solve my problem since this connector was not going to cut it.

Very easy to install and the quality seems great. Would purchase again
