Question by: Curt M on Sep 1, 2025, 2:27 PM
got a 1/4-18 male pipe thread on a line, and i need to step up to a 1/2-14 female port. is this the right straight adapter?
Answer by: Customer Support on Sep 3, 2025, 1:43 PM
For that thread combo, yes. One end is 1/4-18 male NPTF and the other end is 1/2-14 female NPTF, and it is a straight pipe to pipe steel adapter.
