Product Questions & Answers

trying to tie a 1/4-18 pipe port into a 7/16-20 JIC line, is this the tee that does it?
Question by: Dwayne B on Feb 10, 2026, 9:40 PM
Function-wise, it is a steel tee adapter that takes a 1/4-18 male NPTF on the run and gives you 7/16-20 male JIC 37 degree flare connections for the run and the branch.

Question by: Wes P on Feb 15, 2026, 3:27 PM
In plain terms, it is a steel tee adapter in the Eaton Aeroquip 2028 series that connects external pipe thread (1/4-18 male NPT) to 37 degree flare JIC (7/16-20 male) on the run and the branch.
