Steel Metric Flareless Fitting, 10.00 mm L Series Union Tee

For sure, it’s an equal union tee in the L Series with 10.00 mm ends on all three ports, so it’s meant to join three same size metric flareless connections.

As a metric flareless fitting, it's made to connect 10mm L series tubes. Double-check that your lines match those specs for a proper fit and seal.

A union tee in the L Series flareless style joins three separate tube lines at a single point, all at the same 10mm tube size. So yeah, you can branch a single feed into two directions or bring two lines together into one run. Since it's an equal tee, all three ports are the same size, meaning no reducers needed if your tubing is all 10mm throughout.
