Information

The SharkBite Flexible Coupling Hoses are used in residential and commercial applications to easily connect CTS pipe in any combination. The connectors are EPDM knitted with braided stainless steel. The hoses are available in 1/2″ and 3/4″, and are 18” in length. The SharkBite connection allows the installer to connect to Copper, PEX, CPVC and PE-RT tubing and eliminates the need for an additional transition fitting.

Rated 2 out of 5 by from Black stuff staining my tub I purchased this item after it was recommended by the plumbing associate at the store. While purchasing a replacement water heater. He told me of how great this product is and how it reduced his install times by 50%. And that this item has a 25yr. warranty.Three years later. I begin to find black flakes in my water. After doing a little research online. I've found numerous complaints of this item causing black flakes after a couple of years due to the inside of the hose deteriorating. I removed this item from my plumbing and sure enough. Black flakes were coming from the inside of this item.

Rated 5 out of 5 by from Needed emergancy water supply repair. This product just saved me from a serious chewing out by my wife. During the remodel of the spare bathroom the over aggressive use of a demolition tool managed to damage the main 3/4" supply line to both bathrooms. A quick trip to my local Home Depot and conversation with the staff there had me headed home with this flex connector. A couple of quick tube cuts, push the connectors into place and within an hour of the damage I had a no leak temporarily repair. The main bathroom was back in service before my wife was home from shopping. Permanent repairs will be done later as part of relocating the sink and shower later in the remodel. Thank you Home Depot!

Rated 1 out of 5 by from Quick Installation, but inside rubber deteriorates I bought this sharkbite braided flex connector 2-3 years ago and placed it on the hot water side of my water heater. I just recently started noticing black rubber flakes when I ran the hot water into my tub. After months of research and checking things out I found that this hose has rubber inside of it that deteriorates after several years. I had to replace it. If I had knowledge of this problem I never would have purchased this product. I used other sharbite products with no problems, but this one is a bust. Do not buy this item.

The main reason for less than five stars lies with the fact that it is not completely flexible. If you are attempting to connect two pipes that are at a sharp angle to each other, but less than about 9 inches apart, the line may kink and not allow sufficient water flow. As to most other applications, this is a very convenient method of joining two pipes without soldering. Be certain to mark the pipes 1 1/8" so that the connection will be tight. We have used the various SharkBite products for several years, with no problems or leaks.

Rated 5 out of 5 by from This is a product every homeowner should know about, to avoid paying a huge emergency plumbing call. First and MOST important... This is NOT A PERMANENT FIX. The 18" hose is made of braided stainless and the ends made of copper. The combination mades a flexible hose to bridge a gap due to failure of existing pipe. However, the combination of metals which touch results in Galvanic Corrosion, think of a nail dropped in a tin can of water, over time the nail will deteriorate. Likewise with this pipe, but not for at least a year, so it is also good if you are remodeling and need to take a section out of service but still need water beyond the gap. The simple steps. Turn off water & use a pipe cutter (not a hack saw as the pipe needs to be round after cut to work with the coupling) to remove the damaged section of pipe. Use steel wool or sand paper to remove rough edges or burrs (so the plastic which creates the seal isn't damaged). Push each end of the hose connector fully over each of the freshly cut and deburred pipe ends. Turn water back on. Make appt for professional plumber or handy-friend since you now have time and aren't under the gun of having to deal with a huge leak in the middle of the night. If you want a permanent fix you want 2 of the shark bite brass couplings and a piece of brass pipe (or cvpc to bridge the failed section) As there is no mixed metal contact the Galvanic Corrosion isn't a factor. I had a hot water heater (point of use type) fail in my laundry room and was leaking on the floor, it was 5 minutes to close at HD and rand in and was directed to this to bridge the gap and told about the pipe cutter. About $27 later I was home and followed the directions and within an hour of finding the leak I had it fixed. Now I just got the replacement heater (which was under warranty) and I'll put it in after the holidays when I have time off work. If I had called a plumber I know the cost of the emergency call would have been 3 to 4 times more than this resolution.

Rated 2 out of 5 by from Black specks in water I bought this to install my water heater. I love shark bite connections but the interior EPDM has broken down after about two years and is all over the shower and laundry. I would not recommend this product. I would steer clear of EPDM for this application.

Rated 5 out of 5 by from Excellent Product! The PEX line to my master bath sprung a leak where the PEX was bent to enter the wall from the attic. Since the regular PEX adapters are not recommend for use on bends, this flexible supply line was the answer. Installation was simple and so far it has not leaked. I bought a couple of spares to avoid having to make an emergency plumber call in the future. Although I have no intention of leaving this item as a permanent fix, it did work as advertised and got my water supply restored quickly.

Hi, I'm installing a hot water tank with shark bite flex hot water connectors (2nd time I've done this). The new tank has plastic inserts - the manual says they're "heat traps" - in the connection nipples. Should I keep them in place or remove them?

sharkbite flexible hoses are good to use in crawl space ( not heated ) ?

Asked by: yogi s
Hello, This item may be installed in a crawl space but the water inside the pipe, hose and fittings must be protected to avoid freezing. Water that freezes will expand and create very high pressure that can cause damage to these products. Regards

how to release the coupling

Asked by: david davani
Hello, To release a SharkBite fitting please follow the steps shown below. Please note that pulling on the fitting or pipe prior to compressing the release collar will make removal more difficult. 1. Place the SharkBite disconnect clip around the pipe with the non-branded face against the release collar. If using the SharkBite disconnect tongs, place the teeth around the fitting assembly. The fork end with the SharkBite brand logo should be positioned around the pipe and the other end around the neck of the fitting. 2. Push the clip against the release collar and pull the pipe with a twisting action to release the pipe. If using the SharkBite disconnect tongs, squeeze the tool with one hand and pull the pipe with a twisting action to release the pipe. 3. Check the fitting and pipe end for damage. The fitting and pipe should be free of damage, foreign objects and marks on the outside diameter. If the pipe is damaged or marked, then cut and use a new section of pipe. Best regards,
