SharkBite U094LFA Straight Connector Plumbing PEX Fittings, Push-to-Connect, Copper, CPVC, 1 Inch x 1 Inch FNPT, Brass, 1" x 1"

The thing you need to remember with these is that you have to prepare the pipe for the shark bite. I used these for PEX-B and copper on either side of a spin down pre-filter. The FNPT part works the way they always do. I am paranoid so I used tape and joint compound. It is necessary to de-bur the pipe for the SharkBite end, or you can damage the O-ring inside the connecter. For the PEX side I understand that if you twist it as you push it in the inner sleeve will find its way into the pipe to support it. I didn't have the feel for this and damaged the first one I tried because it hung up on the PEX. So I took the one out of the copper end and stuck it in the PEX before pushing it into the connector. No more issue. I didn't have this issue with half inch ShrkBite connectors.63 crimps, 10 shark bites, 10 NTP connections and not one leak. There was a suggestion of moisture on the two NTP pressure gauge connections, so I gave them another complete turn and they dried out. Not sure if it was just that the joint compound was shiny.

Everyone knows how well sharkbites works. It's idiot simple and works fantastic. I couldn't find a couple of fitting with the Sharkbite name, so had to buy a different name brand. I thought they are the same. They work the same, but the fit of the Sharkbite original is a bit tighter. A bit less play. Definitely a better fit than the imitation fitting.

These fittings are great for the DIY plumber. You must get the separate tool or you will struggle installing these.

Added a filtration system to my house and used all Sharkbite. So easy!

Work as expected
