Question by: Tony S on Aug 31, 2025, 7:00 PM
got a setup with 3/4-14 nptf ports, is this tee the right one for tying a branch line in
Answer by: Customer Support on Sep 1, 2025, 8:46 PM
For tying in a branch, it’s a pipe to pipe steel tee with 3/4-14 NPTF threads on all three ends, so it matches 3/4-14 NPTF connections on the run and the branch.
Question by: Tony M on Mar 17, 2026, 3:06 PM
fitting's got a male NPT on the branch and female NPT on the run -- is that right for splitting off a line without losing the main flow path?
Answer by: Customer Support on Mar 19, 2026, 6:38 AM
That's exactly how it works. The branch port is 3/4-14 male NPT and the run ports are 3/4-14 female NPT, so you can tap into an existing line through the run while adding a branch connection off the side. It's a pretty common setup when you need to pull a signal or feed a secondary circuit without breaking the main line apart.

trying to tee off a 3/4 npt line, is this one 3/4-14 male on the branch and 3/4-14 female on the run?
Answer by: Customer Support on May 19, 2025, 3:43 PM
Function-wise, it is a tee adapter that gives you a 3/4-14 male NPT branch connection feeding into a 3/4-14 female NPT run connection, so it works for splitting or adding a branch off a 3/4 NPT line.
Question by: Harvey R on Dec 25, 2025, 8:54 PM
Will this tee fitting work for hydraulic applications on my tractor?
Answer by: Customer Support on Dec 27, 2025, 6:37 AM
This Eaton Aeroquip tee adapter is suitable for most hydraulic systems, as well as grease and instrumentation applications.
