got a gauge port tee with 9/16-18 threads, is this the same deal or am i off a size?

Question by: Dale R on Oct 31, 2025, 1:51 PM

For thread match, the A and B ends on this part are both 9/16-18, and the drill size on both sides is listed as 0.172. It is a branch tee style that includes a gauge port.

got a 1/4 inch tube line running off a hydraulic block and need to tap in a gauge port without adding a bunch of extra fittings. this piece do that in one shot?

Question by: Sheila C on Jul 8, 2025, 4:53 PM

That's exactly what this fitting handles. It's a branch tee configuration that combines a straight adapter with a built-in gauge port tap, so you're not stacking multiple fittings to accomplish the same thing. The SAE ORB port on the branch is 7/16-20, which is a common gauge connection size. The main line runs 9/16-18 threads on both the male and female ends, and the tube OD it's built for is 1/4 inch. One fitting, one installation, gauge port already there.

Wondering what size drill and thread this branch tee uses for the gauge port?

For the gauge port on this branch tee, you're looking at a 0.172 drill diameter and 9/16-18 threading.
