SUNGATOR1/2 Inch Male Adapter, 1/2 Inch MNPT Adapter, No Lead Brass Push-to-Connect Plumbing Fittings for Pex Pipe, Copper, CPVC, with 1 Disconnect Clip, Pack of 12

As stated in another review for 90 elbows, these were easy to use and I have had no leaks. I see no difference between these and higher priced brand at the box store. works as well too.The plumber who installed my tankless heater used plastic fittings for the PEX crimp ons and, I felt the smaller diameter of the plastic with many bend's probably reduced my water flow. After installing these and other fittings, the water flow actually increased 3/4 gallons per minute. This is far superior to the plastic PEX connectors for PEX

Great fitting that worked perfectly. I stripped a fitting underneath my Winnebago View Kitchen Sink and this fitting fixed the problem. The original recreational vehicle coupling was discontinued.

It's brighter and seems well made. A lot less expensive than the shark brand. Previously used 1/2 inch connectors to connect pex to copper in both interior (under sink) and external (faucet). Bought these based on that experience to connect threaded copper to pex to supply a bathroom.

I bought these specifically because they said it had 1/2" NPT male thread.However, they don't seem to mesh perfectly with the 1/2" NPT female receptacle I am using them with.They turn into the receptacle smoothly enough, but then come to a hard bump where I have to use a wrench harder than up to that point.Also, the webpage description shows them using them into a water heater receptacle, which I believe to be straight thread, not NPT.I have used Teflon tape AND pipe dope just make sure it doesn't leak, seems ok, but is not the same seating profile as what I know to be NPT thread.

Sealed perfectly the first time and the next 4 that I had to remove the PEX tubing. Only complaint is that I had to hold it pointing up to easily insert the tube. Zero probs since install

They're great cause you don't have to have any special tools. Would definitely buy again.

Worked just as it should , price is much better than big box stores if you can find them May not be a shark, but it sure isn’t a guppy!
