The SharkBite Water Heater Connectors are used in residential and commercial applications to connect the hot and cold supply lines to the water heater. The connectors are EPDM knitted with braided stainless steel. The connectors are available in 12 in., 15 in., 18 in. (with and without ball valve) and 24 in. lengths. The SharkBite connection allows the installer to connect to copper, PEX and CPVC tubing eliminating the need for an additional transition fitting.

Rated 5 out of 5 by from Easy install, no leaks, quality product !! I used 2 11'' flex hoses and a in line ball valve on my new hot water tank install and it made what might have been a tough job very easy

Rated 5 out of 5 by from How did I not know this kind of product existed?!?!? My biggest worry about my water heater switch out was getting it reconnect to the water line. I have a pretty handy friend that offered to help me switch it out. When we grabbed the water heater he picked up a few of these to get it reconnected to the water line. I was like WHAT!! it just pushes on the the copper piping and threads onto the water heater! I was in shock at how simple this connector made my water heater switch out! Its strong flexible and so far shows no signs of having any problems with heat from the water or the vent line on the water heater. I will continue to use these on any future water heater or water softener switches. Thanks

Rated 5 out of 5 by from Time Saver This product saves you time and a headache. Why struggle with ensuring your new water heater is perfectly lined up with the old one, which will never happen with sizing differences. Even worse why concern yourself as to whether you perfectly sweat those lines? These shark bite connectors save you the hassle. Grab some thread tape and screw onto the water heater. The other end is a compression fitting for your current pipe so it simply snaps on. That is it. With all the time saved and lack of mess from soldering to clean up you can have yourself a beer.

Rated 5 out of 5 by from SharkBite Products My water heater started to fail and was leaking in the drip pan. I am handy with many things but plumbing is definitely not a strong point for me. Every plumbing job I tackle requires multiple trips to get the one thing that I forgot. While picking up the water heater the salesperson suggested that I try the SharkBite products to connect my new water heater, what an absolute wonder these are. After draining and disconnecting the heater it was a 10 minute job to reconnect the piping to the new heater. All you need is a tubing cutting tool, the tool to mark the correct placement of the SharkBite connector. It is a very neat and effective way to do plumbing. Best product that I have ever used, it made my poor plumbing skills look professional

Rated 4 out of 5 by from Works good with only one downfall The idea of just pushing the sharkbite connector on simplifies the install bigtime, and even allows for different water heater configurations in that the downlines don't have to line up exactly. Only issue i have found, and its really not an issue is that the old setup is 3/4 copper, and with the sharkbite connectors there is less inner diameter, thus with the cold water pressure feeding your tank, vs your cold water pressure at the faucets... your old settings on faucets will change to get the same heat out of it. no biggie. Great solution

Rated 1 out of 5 by from Rubber failure Unfortunately the black rubber lining failed in about one year. I started noticing small black rubber particles when filling the bath tub for the kids. I looked online and sure enough the sharkbite hose are prone to failure. I checked several other faucets and they had black rubber particles practically blocking the small faucet filter. Our shower head was also clogged with black rubber particles. I like the idea, but unfortunately they just don't last and will put black rubber particles into your hot water supply.

Rated 5 out of 5 by from It is what is, and it works. I used this to connect my old Copper lines to the new water heater. Oh how much easier it was than working with solder, flux, and a torch. And if you purchase the "disconnector," you could possibly use it 20 years later when you might have to replace the water heater again. Similar to prepping for soldering, except you DON'T have to emery cloth the copper. Easily worth the extra expense for the fitting. Will probably use the same style to replace leaking connections on my pex lines for my water conditioning system. Pretty self-explanatory, but I used the website to confirm what I assumed for installation. Was impressed that the associate at the store recommended this over solder, etc. He made the comment: "After being in plumbing for 25+ years, even I want to use something as simple and idiot-proof as this." Pretty much, "Nuff said?"

Rated 5 out of 5 by from Easy to use I prefer to use copper, but had just finished sweating a water heater into place and discovered the nipple to the WH needed another 1/4 turn. That was not going to happen and it was getting late. I went to HD to get a new nipple planning on disassembling then re-sweating the copper. This Shark Bite assembly probably saved me an hour of labor as well as frustration. It is on, no leaks and we are all happy.

Is there any concern if the flex pipe is near a 'B' vent that the piping might melt ( I understand the inner tubing is plastic?) 

Asked by: murman
Greetings Murman, The inner lining is Rubber but there is plastic on our SharkBite fittings. As long as the air coming out of the vent isn't over 200 degrees Fahrenheit, you should be okay.

Does your flexible hoses for water heater connections contain "chemicals known to the state of California to cause cancer and birth defects or other reproductive harm"? If so, what are the ramifications on young teens?

Asked by: Billorights
Greetings Billorights, The chemical is lead. Any brass fitting or product is going to contain traces of lead. Our product is considered in the US and to the state of California to be Lead Free. Our products contain less than .25% of lead. There should be no health concerns when using our product. The reason we have that warning label on the packaging is because California will not let us sale in their state unless its on there. Any items that have lead or come in contact with lead during the manufacturing phase must have that warning label.

can a flex tube be installed horizontally and then flexed 90 degrees ?

Asked by: Drake Masters
Greetings Drake, There is no reason, on our end, that our Flex hoses can't be installed this way. As long as you have enough pressure, the system should be okay.

What is the size washer for a 3/4 flex hose? I have tried a hose bib and it appears to be slightly too large. Where can I find the correct washer?

How tight should one make the threaded end? It has a washer correct. So does one make it snug, or real tight, or a couple turns? One of my threaded ends is weeping and tighten pretty hard.

Asked by: Fred
Greetings Fred, Should be able to hand tighten to complete the seal. We also suggest using plumbers tape to enhance the sealing ability.

What is the minimum bend radius for your 3/4" radius hot water flexible water heater hoses?

Asked by: eferg
Greetings Eferg, We would suggest not bending the Flex Hoses more than you would our PEX tubing. Our corrugated may have a slightly more bend radius, but we can guarantee our Braided and Corrugated would work if you keep it within our suggest PEX Tubing bend. Please see Below: Size Bend Radius 3/8" --- 4" 1/2" --- 5" 3/4" --- 7" 1" --- 10"
