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 1 out of 5 by from rubber liner deteriorates In 2011 I installed these braided flex connectors from sharkbite; it was an easy install no leaks I was very happy, but after 2 years my faucets strainers were being clogged with small fragments of black rubber. I finally found the water heater was loaded with the rubber and found the rubber liner in the sharkbite flex line was deteriorating. I called Sharkbite and they said they changed the liners and if I bought new lines manufactured after 2011 that they would have the new liners. That was late 2013 or early 2014 and now here it is 2016 and the lines have deteriorated again. I don't recommend these and will not be suckered into them again.

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 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 turned a "call a plumber" into a "I think I can" job My old water heater was a standard 48" tall unit in a 36" tall crawl space. Someone dug a hole, lined it with plastic, set two concrete blocks in it, and placed the 48" tall water heater on top of the block. I'm not a plumber and don't trust myself with a torch under a house. With these fittings, I was able to get the job done. I cut the old copper pipe off, installed these, connected to the new water heater and BINGO! It works, no leaks. Actually, one of the two I bought leaked. Not sure what the problem was. I returned to Home Depot, exchanged for a new one and it's all good.

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.

Can I use the 3/4 x 3/4 FIP 12" flex hose to connect from 3/4 copper tubing to a water filter on my incoming water line ? I want to use flex hose instead of having to bend and reroute copper lines.

Asked by: Greg E
Good morning, These hoses are designed to connect to potable water system heating source that stays below 200 degree Fahrenheit and 200 PSI. These hoses must be accessible at all times. If you are using it outside the water heating source, you should make sure that the product is kept in a clean place and is accessible.

Recently I bought a water heater shark bite and just assumed I need to pull out the tube liner because I was not connecting PEX pipe. Will removing the tube liner affect the performance of the connection?

Asked by: DOityourselfer
Good afternoon, You can remove it if you are using it on Copper or CPVC. We recommend leaving it in as it won't effect anything in the system. If you've already removed it and installed the pipe, you don't have to worry about putting it back in. Your hose will work as it should if you connect to Copper or CPVC.

Hi I'm looking for a male on one end and female on the other in 3/4's insted of the push fitting, or and adaptor that goes into the push fitting and the provides the male fitting?

Asked by: jorgan
Good afternoon, We do not offer a male threaded adapter nor do we offer a hose with a male connection. You will have to use a hose plus a short piece of Copper, PEX, or CPVC and add a male threaded adapter to complete this connection.

I have a leak in my PEX water line underground. After digging through the stony ground I found the the point of the leak is at a bad over a rock. Can I use the flex to connect the cut out sections of the water line undrground?

Asked by: olab
Good morning, No. Our Flex hoses are only certified in accessible locations and not for underground burial. We do not recommend using this item to make a repair on your like. Our Standard SharkBite Push-To-Connect are certified for underground use.

Do these hoses isolate the heater electrically? My current heater has 220 grounded to the junction box on the heater which is electrically grounded via the copper pipes.

Asked by: jlwing
Good morning, No. Our SharkBite products do not conduct electricity and can cause a break in the ground. You will need to create a jumper to bypass this item.

My sharkbite has disintegrated and the rubber is coming out leaking in my tub.  i need to replace it but can't remove the old shark bite, could you advise on how to remove it?

Asked by: gatorfan
Good morning, To remove a SharkBite fitting, use the disconnect clip to depress the release collar and release the pipe from the fitting. Below is a link to a youtube video that will show you how to disconnect the fitting from the pipe. http://www.sharkbite.com/how-to/sharkbite-push-fit-fittings-how-to-install-pex-tubing-copper-tubing-and-cpvc-tubing/
