Designed for equal-flow branch connections in metric hydraulic lines, the Steel Metric Flareless Fitting, 12.00 mm L Series Union Tee from Eaton Aeroquip provides a reliable three-way junction in a compact steel body. The L Series designation indicates a light-duty pressure rating suited to standard industrial hydraulic circuit requirements, while the flareless design simplifies assembly without the need for tube flaring.
All three ports accept 12 mm OD tube in a flareless bite-type configuration, making this union tee well suited for connecting equal-diameter lines in mobile equipment, machine tool hydraulics, and general industrial fluid power circuits. The all-steel construction supports use with a broad range of hydraulic fluids, as confirmed by Eaton Aeroquip's published fluid compatibility data for this product family.
Three-way tee for 12mm tube, all three ports the same size on this thing?

All three ports on this union tee accept 12 mm OD tube using a flareless bite-type connection, so yeah, it's a true equal-port configuration. No reducers or adapters needed if you're working with matching 12 mm lines throughout. That makes it pretty straightforward for branching a single line into two or tying three equal-diameter runs together at one junction point.

How much pressure can this tee handle, roughly speaking?

This L Series union tee is designed for light-duty hydraulic applications, so it's best suited for standard industrial hydraulic circuits rather than high-pressure systems.
