Product Questions & Answers (4)

Question by: Kent W on Jan 17, 2026, 4:13 PM
trying to step a 3/4 pipe thread down to a 1/4 female port, is that what this bushing does?
Answer by: Customer Support on Jan 19, 2026, 1:58 PM
For stepping down pipe threads, it goes from a 3/4-14 male NPTF on one side to a 1/4-18 female NPTF on the other, so it adapts a larger male pipe connection into a smaller female pipe port.
Question by: Dean C on May 1, 2025, 6:57 PM
What's the outside and inside thread size on this adapter?
Answer by: Customer Support on May 3, 2025, 3:12 PM
It's a reducer, going from 3/4-14 male NPT down to 1/4-18 female NPT.
Question by: Billy F on Sep 28, 2025, 7:30 PM
trying to hook a 1/4 npt gauge line into a 3/4 npt port, is that what this bushing is for?
Answer by: Customer Support on Sep 29, 2025, 8:50 PM
For reducing a larger pipe port down to a smaller pipe connection, this adapter is a straight reducer bushing with 3/4-14 male NPT on the outside and 1/4-18 female NPT on the inside.
Question by: Johnny B on Nov 16, 2025, 10:58 AM
Got a line running 3/4 NPT male and need to step it down to a 1/4 female port. This the right bushing for that?
Answer by: Customer Support on Nov 18, 2025, 7:52 AM
That's what this adapter handles. The male end threads into a 3/4-14 NPT female port, and the female end accepts a 1/4-18 NPT male fitting. It's a reducer bushing, so the whole point is bridging that size gap between two pipe thread connections without needing extra fittings in between.
