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 Best plumbing product I've used... Had to change out a water heater this weekend and of course, none of the water connections lined up. I didn't really have time to rebuild all the copper and sweat all those connections so I thought I would give these a try, simplest, most effective product I've used on a plumbing project... test fit, cut pipe, sanded burrs and slipped right into place. No leaks... amazing!!

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 You need this for the new gas water heaters. If you have a gas water heater, you are in for a surprise when you go to replace it. The new standards have changed the size enough that the old connections are not going to fit. The new designs are taller, and bigger around then the old ones. Because I don't like messing with gas lines, and because the water lines were too long anyway, I moved the hater a bit so the gas line fit. Then I cut the water lines back, and used 2 of these. Installation went easy. Because they are flexible, I didn't need to line things up. With the "Push-to-Connect" connector, I didn't need to solder anything. Talk about easy. And they are even rated as a dielectric connection.

Rated 5 out of 5 by from Easy hot-water connect & no leaks The SharkBite 1/2 in. x 15 in. stainless steel push fit x FIP flexible water heater connector is a great new way to connect a water-heater or boiler to your home system. The female threaded ends screw onto the nipples from the tank with a bit of teflon tape to prevent sticking or corrosion and the SharkBite ends push right over cleaned and prepared pipes from the hot water inlet and cold water feed. When the water was turned back on, no leaks were detected from the new stainless steel mesh connectors and not even a droplet was released by the push-on ends. The push-on ends will require a special clip (sold separately) to remove. I recommend these SharkBite connectors for both do-it-yourself and professional plumbers.

Rated 4 out of 5 by from the war against water heaters ITEM:3/4 in. x 24 in. Stainless Steel Push-Fit x FIP Water Heater Connector I bought the steel web wrapped water heater connector because the water heater top is difficult to reach and has limited space to apply the wrench to tighten or loosen. Note that this hose is replacing an identical hose that began to leak in less than two years use. Even with the failure of the previous hose, I still bought another. The hose failed because the angle of the hose was too sharp. This time I put on a longer feeder hose so that there was an easy curve. Do not let this hose kink.

Rated 5 out of 5 by from Great time saver I did not have a torch and did not want to buy equipment to sweat in the connecting copper pipe while putting in my new water heater recently. This 24in flexible water heater connector was only slightly more expensive than normal fittings and pipe but much simpler to install. I only had to clean off the surface of my copper input and output pipe from the wall, fit the shark bite end over the copper pipe, then screw on the water heater screw connectors on the top of my new tank. The shark bite has not leaked since installing it several weeks ago so I am happy.

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.

Should a dialectric be installed on the water tank when using shark bite flex connector?

Asked by: Craigeich
Greetings Craigeich, Our SharkBite fittings will not connect directly to Galvanized pipe. If you are using this type of pipe, a dielectric union will need to be installed.

Can I use this flexible connector on the pressure release line to connect to the existing copper pipe that goes out to the drain?

Asked by: Dmall
Greetings Dmall, Our products are not designed or recommended to be used on drain lines or systems. Dealing with water heaters, they usually release around 210 degrees Fahrenheit and our fittings are only suitable up to 200 degrees.

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?

At this time, we do not have these washers available to purchase but will be happy to send you out a replacement so you can get your system back up and running!

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.
