Question by: Warren K on Mar 24, 2025, 1:59 PM
trying to tee off a 1/4-18 female npt port, will this give me two 9/16-18 jic ends on the run?
Answer by: Customer Support on Mar 26, 2025, 6:27 AM
Function-wise, it is a steel tee adapter with a 1/4-18 female NPT branch and two 9/16-18 male JIC 37 degree flare connections on the run, so it lets you split off from the NPT branch into two JIC flare ends.
Question by: Janet P on Sep 19, 2025, 7:42 PM
So this thing's a tee, right? Does that mean it's got three openings? Just wanna make sure I'm picturing it right before I order.
Answer by: Customer Support on Sep 21, 2025, 9:03 AM
That's right, this is a tee adapter, so it features three openings for connecting different lines or components. One port is a 1/4-18 Female NPT branch, while the other two are 9/16-18 Male JIC 37 deg Flare runs.
