The SharkBite straight coupling is the easiest plumbing fitting to join any combination of Copper, PEX, CPVC, PE-RT or SRD9 HDPE pipe together. With no soldering, clamps, unions or glue required, it’s as simple as inserting the pipe into the fitting deep enough to be sealed by our specially-formulated O-ring. Once inserted, the stainless steel teeth bite down and grip the pipe. This push-to-connect fitting is designed for potable water and radiant heating (including underground or behind-the-wall) applications with no access panels required. It is rated up to 200°F and 200 psi.

Rated 5 out of 5 by from Hot water lines--no problem! I bought a pair of the 18" braided stainless lines w/shut-off valves to connect a new hot water heater. I was extremely skeptical at first. Surely anything that said "push on and walk away" was too good to be true. I pushed them on and walked away. Never saw even a hit of a leak. I am completely sold. You will want a simple copper pipe cutter (I got the compact one from Ridgid for ~$12). It gives you a nice, even squared up opening to push the connector on. Still cheaper than a torch, flux, solder, more copper pipe (which you'll still need the cutter for). If it leaks when you put it on, it's not installed correctly. But it's hard to mess these up.

Rated 5 out of 5 by from excellent product I got my house last fall, was the first house I ever owned with city water, the plumbing was all blown apart, I thought id try these out, used a combination of pex and copper with the shark bite fittings, everything went together good, no leaks, this summer I hooked up my new garden hose and within 5 minutes the end popped off, seemed like the water pressure was high, I went and got my pressure tester and couldn't believe what I saw 165 lbs, called the town they said I need a pressure reducer, just installed one today, these fittings got to be tough with that kind of pressure for a year, I wont hesitate to use them in the future.

Rated 5 out of 5 by from Extremely easy to use I had to move a water supply line to install a new toilet. I found the Sharkbite range of products and I am so impressed I tried to see if I could buy stock in the company. (I don't think they are public.) I cut the existing pipe, smoothed off the cut end with the orange sharkbite tool and then slipped this coupling on. I ran PEX tubing up through the floor to the bathroom above. Each item just pushes on in place and not a drop of water came out when we switched the water supply back on. Perfect!

Rated 5 out of 5 by from SHARKBITE - best push-fit These are the best push-fit on the market. Are these worth the expensive price, ABSOLUTELY. Whether in tight quarters (against floor board and joist) or in wide open spaces these always work like a charm, no muss, no fuss, no leaks, no fires and no aggravation. Best of all plumbing can be disassembled in a breeze if need be. Try that the old fashioned way. So no matter your pipe material (pvc, cpvc, copper) Sharkbite's rock. Also used on my 3/4" air line runs in the garage (150psi) for years now. Hope this helps.

Rated 4 out of 5 by from Fast & Convenient yet some issues I have used these in many repairs at my cabin and love the ease of use. However, freezes have caused failure where standard solder joints hold up. The expansion and contraction seems to lossen the "bite" and the coupler just lets loose on one side, even when the pipes have been drained and blown out. I have replaced this one spot three times thinking that I had a slight dip in the line up, but that did not solve it. The last time I pushed up harder on the pipe-so far so good.

Rated 5 out of 5 by from Amazingly Easy toUse I just used these for the first time to repair a frozen/ruptured copper water line inside a finished wall. Before this I would always have used new copper lines and fittings - but by using this (I had a 1/2 and 3/4 line to repair) I only had to make a small hole in the drywall, and the plumbing repair only took about 1/2 hour. These fitting are a little pricey compared to copper, but the transition from copper to PEX and back to copper was amazingly easy and leak free. These would be great for anyone, but a must have of you are not adept at sweating copper fittings.

Rated 5 out of 5 by from Enables plumbing work in very cramped spaces. Awesome. I can't say enough good things about the sharkbites. They are fantastic. I had a water leak in a shower set up, and when I removed the shower handle plate I discovered the whole setup was incorrectly installed (e.g. the shower valve was just hanging there without being attached to anything other than the 4 pipes connecting to it). Soldering, I would have had to break a bunch of tile to rebuild the shower. But using sharkbites and a very small pipe cutter, I could reach in behind the wall and cut pipes and install the connections just through the shower valve/handle hole. That saves so much work. We'll see in 20 years whether any of the concerns around sharkbites are well founded. So far I have found them to work great.

Rated 5 out of 5 by from Best Invention Sharkbite are simply a no brainer when it comes to DIY repair or adding on to existing pipes. All you need to do is cut - clean and snap on. I have never had or seen a Sharkbite connection leak. I use them for everything. If i was a plumber i would recommend not using it only cause it would take away from their profit. Any DIYer can do this without their help. Sharkbite makes every connection possible. From Sink values to 1/2 to 3/4 adapters just to name a few. [This review was collected as part of a promotion.]

3/4 inch copper running under deck in Minnesota. I need to reposition my sill cock. Can I use a shark bite in Minnesota outdoors. My main shut off is inside and is always closed and drained before winter. Will a shark bite connector withstand our winters?

Asked by: Chris E
Good morning, Our SharkBite fittings can be used outdoors and won't have any issues with the cold air. You would need to make sure no freezing occurs in the line that the SharkBite fitting is connected to. As long as there isn't any high pressure freezing, you should be okay to use our fittings.

How do I take a coupling connector apart, in order to drain my pipes?

Asked by: Jo W
Good morning, If you need to remove a coupling from your line, you will need to use a disconnect clip (link: or disconnect tongs (link: Vendors may not stock all our products, so if they don't have either of these on their shelves, you will need to work with the vendor to place a special order for them.

I have 5/8 copper pipe do you make a 5/8 coupler and or adaptor?

Asked by: Rich Z
Good morning, We make 5/8" inner diameter fittings but are not for potable water applications. If you measured your pipe by the outside diameter and it is 5/8", you are most likely using 1/2" inner diameter pipe. Copper Tube Size (CTS) is based on the Inner Diameter, so our 1/2" fittings connect with 1/2" CTS or 5/8" outer diameter.
