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 Great product The engineer responsible for designing this product needs a medal.....seriously. These connectors make doing plumbing repairs much simpler. Going into situations where sweating copper pipes is restricted or impossible, this is the best solution. I used these to make the transition between copper and pex lines behind the wall for a shower when the copper pipe had previously frozen. They are easy to use as long as you follow the few basic instructions and ensure the pipe is clean, if copper, and securely pushed fully into the fitting. I wish they were more cost effective to use more often. [This review was collected as part of a promotion.]

Do you have a chart of the working pressures? Can this fitting and Pex tubing handle glycol solutions?

Asked by: ZachH
Hello, Pressure loss and flow rates can be found in our specification package. Please see the link below. SharkBite fittings and PEX are suitable for glycol solutions. Thank you

Looking for a connector solution for PEX to copper transition for low pressure hydronic systems (P < 50psi) that would provide full port transition. You'll need to expand the PEX to make this possible but you have an outer shell to compensate somehow.

Asked by: Pierre55
Good morning, Our products don't have any issues being used in a low pressure system. You can use any of our fittings to complete this project.

Pin hole copper pipe leak, bought the coupling piece, hoe much of copper pipe does ut need to be cut?

Asked by: Edwin
Good afternoon, To find out exact measurement of space to cut out, you will take the overall length of the fitting and subtract the insertion depth twice. EX: 1/2" coupling is 2 inches long. The insertion depth is 7/8 inch. Insertion depth times two (2) is 1-3/4 inches 2 inches minus 1-3/4 inches will leave 1/4 inch If you have a pin hole leak, the best fitting to use would be the slip coupling (link: ). This will allow you to cut out up to 2 inches and cover the gap without exact measurements.

Can Shark Bite Fittings be used on Natural Gas Regulator Vent Line, these line are open to the atmosphere and only used to vent small amounts of natural gas. This would seem like a good alternative in some situations than having to braze in fittings

Asked by: JoeW
Good afternoon, We would recommend not using our SharkBite fittings outside of potable water or radiant heating applications. Our products are only tested and approved for these applications.

The coulping same as a union? So I can break downn piping to remove the ball valve when required.

Asked by: Richard W
Good afternoon, No. Unions allow you to thread them on and off to remove devices between them. Our couplings are not designed to be removed and re-used more than four (4) times.
