So, will this tee work to connect a 5/8-18 male SAE flare to a 1/4-18 male NPT? Just wanna make sure before I order.

That's what this ACR Industries tee is designed for – connecting a 5/8-18 male SAE 45-degree flare run to a 1/4-18 male NPT branch.

trying to replace a little tee fitting, are the threads on this one 5/8-18 on the flare side and 1/4-18 on the pipe side?

Question by: Harvey H on May 28, 2025, 7:07 PM

On this tee, the run connection is a 5/8-18 male SAE 45 degree flare, and the branch is a 1/4-18 male NPT.

got a 3/8 tube line running into a tee fitting and need a 1/4 NPT branch off it, does this part cover that setup?

Question by: Terry C on Dec 16, 2025, 12:14 PM

That's what this fitting handles. The run side is 5/8-18 male SAE 45 degree flare, which corresponds to 3/8 inch OD tubing, and the branch comes off as 1/4-18 male NPT. So if your main line is 3/8 OD and you need a quarter-inch pipe thread takeoff, this tee covers both connections in one piece.
