Product Questions & Answers (4)

Question by: Marvin C on Aug 17, 2025, 5:02 PM
trying to tee off a 1/2 pipe line, are all three ports on this tee the same thread
Answer by: Customer Support on Aug 19, 2025, 6:12 AM
All three ends are 1/2-14 NPTF, and each end is listed as 0.5 size, so you are dealing with matching pipe threads on every port.
Question by: Tammy C on Jan 19, 2026, 3:22 PM
Will this tee fitting work for hooking up a grease line to my hydraulic system?
Answer by: Customer Support on Jan 21, 2026, 7:10 AM
These tees are designed to handle grease, instrumentation, and most hydraulic systems, so it should work well for your grease line application.
Question by: Ralph P on Apr 29, 2025, 1:10 PM
got a tee fitting i'm trying to replace on a grease system -- the branch is male NPT and the run ports are female NPT, both half inch. this the right one?
Answer by: Customer Support on May 1, 2025, 8:53 AM
For a grease system needing a 1/2-14 male NPT branch with 1/2-14 female NPT run ports, yes, that's exactly what this fitting covers. It's part of the Eaton Aeroquip 2091 series and lists grease as one of its supported applications alongside instrumentation and most hydraulic systems. The thread spec on all three ports matches 1/2-14 NPT, so if your existing fitting follows that same layout, this should drop right in.
Question by: Roger P on Jan 4, 2026, 5:04 PM
trying to tee off a 1/2 pipe thread line, is this one 1/2-14 npt male on the branch and 1/2-14 female on the run?
Answer by: Customer Support on Jan 6, 2026, 6:45 AM
Function-wise, it’s a tee adapter with a 1/2-14 male NPT branch and a 1/2-14 female NPT run, using NPTF external and NPTF internal pipe threads in the Danfoss/Eaton 2091 series.
