Information

The SharkBite Polymer Push-to-Connect Coupling is an efficient way to join multiple different materials with no specialty tools, solder, unions or glue required. These fittings are lead-free compliant, corrosion resistant, and are compatible with Polyethylene, Nylon, PEX, Soft Copper (must be round and in good condition). Installation is simple, simply push the tubing into the fitting and the stainless steel teeth will grip onto the pipe while a special EPDM O-ring compresses, forming a perfect watertight seal. Approved applications include: water filtration, reverse osmosis systems, ice makers, home/office coffee and beverage dispensing equipment, aquariums, air, gases, vacuum and liquids.

Rated 5 out of 5 by from My GE refrigerator sprung a leak in the waterline when I was out of town and the handyman I sent ... My GE refrigerator sprung a leak in the waterline when I was out of town and the handyman I sent told me I'd need a technician to reinstall it because the condo developer had taken shortcuts and jimmy-rigged the connection using wrap-ties to connect two mismatched tubes. I didn't want to spend 99 bucks for someone to come and tell me I needed a waterline, so I researched pipe connections and found this idea on Youtube. It is the best $8 bucks I've spent. It is so easy to install and made a pro-job look so simple. No leaks...I am very pleased.

IT ENDS UP CUTTING THE TUBE SO WITHIN FEW HOURS WATER IS LEAKING. I EVEN DROVE BACK TO HOME DEPOT AND BOUGHT ANOTHER UNIT BECAUSE I THOUGHT THE FIRST ONE WAS DEFECTIVE. I PUT IT ON AND EVERYTHING WAS GOOD, NO LEAKS. FEW HOURS LATER IS WAS LEAKING AND CUT THE TUBE AGAIN. SO I REMOVED THE BROKEN PEICE AND REATTCHED IT, NO LEAKS. I WAKE UP THIS MORNING AND TESTED THE WATER LINE AND YOU GUESSED IT, IT LEAKS. THE PART IS JUNK!! I AM ONLY USING IT FOR THE WATER LINE THAT IS ON BACK OF FRIDGE FOR THE ICE MAKER. I HAD TO ORDER PART NUMBER WR02X11330 FRO GE AND HOPE THAT ONE WILL NOT LEAK. THESE PARTS ARE GARBAGE. THERE IS ANOTHER REVIEW ON HOME DEPOT OF THIS BRAND DOING THE SAME THING.

Rated 5 out of 5 by from If they leak, you're doing it wrong. I have used dozens of these fittings in my home (I'm not a plumber, just a DIY guy) and they never leak if installed properly. First, make sure you have the right fitting and tubing. John Guest, Pex, Shark Bite, they all make metric and imperial sizes. They look the same, but they are not! Second, you have to have a clean cut on your tubing, no burrs, and most importantly, not "out of round". If you arent using the proper cutter and are using wire cutters, tin snips, or whatever tool you have lying around, it's easy to smash the end of the tubing so it isnt perfectly round any more. This slightly oval end will leak every time. So! Use the right parts and the right tools and you will have no problems. And no leaks. :-)

I bought this coupling to repair, and it was easy to install this coupling. If you are considering this coupling for similar repair, ensure that your tube diameter matches the dia of this coupling. If it's not exact, it won't fit.

Questions

How much length will a 1/2 x 1/2 inch coupling add to the length of the tubing line (in other words after the connecting is made what is the distance between the ends of the tubes)?

Asked by: Jim Col
Good morning, Our Standard couplings will add approximately 1/4" to the line since we have an internal ledge inside that prevents the pipe ends from touching.

Good afternoon, We do not offer any connections to Galvanized water lines. You would need to work with a local store to find out solutions to convert from Galvanized to Copper, PEX or CPVC before using any of our products.
