(S72-6-2) COMP/TEE-MALE 3/8X1/8

That's exactly what it does. The S72-6-2 is a tee configuration, so you get the 3/8 compression connection handling your main line while the 1/8 male thread gives you a branch port off the side. It's a Midland Industries fitting built for hydraulic assemblies where you need to pull flow in two directions from one point without adding a bunch of extra hardware.

For splitting a connection in a hydraulic setup, this is a compression tee with a 3/8 inch by 1/8 inch connection size and a male end on the 1/8 side. If your components match those sizes and you are joining compatible parts, it’s built to make a secure, leak-free connection.

This compression tee is built with durability in mind for demanding industrial hydraulic environments. It's designed to provide a secure, leak-free connection, which suggests it should handle that pressure, assuming the rest of your system is rated accordingly.
