Connecting 3/8" PEX to a standard water shutoff
Hi folks. I just moved to Tennessee from Michigan. I'm installing an under sink water filter. It's a unit that uses 3/8" PEX on both ends. The connection piece that they gave me to connect to my cold supply is useless for my circumstance. What's the best way to connect PEX to a standard cold water shutoff valve without using special tools? Can I use an old fashioned nylon compression fitting like the ones commonly used for ice maker connections?
Thanks for your attention.
Delta supplys no insert for DST Pex faucet installation?
Installed new Delta DST kitchen faucet, and because supply lines were so long, I cut off the manufactured ends and opted to use the nylon compression rings supplied with the kit to 3/8" angle stop valve No insert is provided. Instructions say to turn compression nut 2 full turns after hand tightning, that seemed way too tight at first try, but hot water side let go within 15 min. flooding kitchen. I then retightened to much tighter and then removed tubing to see that nylon compression ring was crimping tubing. And did a pull test. I installed ring in correct manner and deburred end after cutting with standard tubing cutter. It's holding now, but I can't find any recommendation to use an insert inside Pex tubing except on your site here?????? It seems standard practice with softer polybutylene?????? A call to Delta, just produced a woman trying to blame me for not cutting tubing correctly!! I'm an aviation mech. and have been making tubing connections for 40 yrs. Tubing was cut square and deburred. Connection makes me nervious, I always turn off my outside incoming water valve when I leave home, because all my plumbing is 20 yrs old....
