Hi Stu, thanks for writing in. The threaded end of this tee is 1" female NPT and will accept a 1" male NPT thread, although you should not thread PVC into brass directly.
The FNPT piece is removable, but there is not a lot of space to get the disconnect clip in. The tongs may work better but it could still be tough to get it released.
If the expansion tank has the same size NPT thread, that would make for an extremely easy connection.
This "Female Centre" tee (part U462) has 3/4" SharkBite connections on the two ends with 3/4" female threads in the middle port, which is slightly off-center.
Adam, The "T" is not threaded, it is a shark bite fitting where the pipe (pex or copper) is simply pushed into the fitting. It is safe for potable water.
I have used this and it's not threaded. Will accept led tubing or copper. I used it for potable water. Sent from my iPhone
The tee is threaded on the branch and you can thread anything into the female threads. I used one (with a bushing to 1/4") to install an icemaker supply line and it worked great.
It is not threaded. It is used for copper pipe only. It is leas free. Sent from my Kindle Fire
hi adam You will receive a tee like the one shown along with a threaded insert. They also sell the threaded inserts separately which i found them very useful. They can be used for pex or copper. These fittings come with little plastic inserts also which you should remove if using them with copper. As far as my knowlege goes, these do contain lead, yet can still be used for potable water. I don't think the lead has any way of leaching into the water. eric
This is threaded only on the tee (bullnose).
FNPT stands for female nominal pipe thread. This is threaded on the inside of the fitting.
