With this T-Piece you can screw in three fittings.
The three threads are G1 / 4, so you can turn three fittings with G1 / 4 threads in this T-Piece.
Handy for splitting a loop!
Also very useful for temperature meters, to measure the temperature "inline"! See the photos under "images" for examples of use.
