Product Questions & Answers (3)

Question by: Howard C on Apr 9, 2025, 5:29 PM
Will this adapter work for connecting a 1-1/4" male pipe to a 1" female swivel?
Answer by: Customer Support on Apr 11, 2025, 10:09 AM
Yes, it's designed for exactly that: connecting a 1-1/4-11-1/2 male NPT to a 1-11-1/2 female NPT swivel.
Question by: Dale A on Feb 14, 2026, 6:11 AM
got a line running 1-1/4 male NPT and need to connect it to a 1 inch female swivel setup. this the right adapter for that?
Answer by: Customer Support on Feb 16, 2026, 6:54 AM
That's exactly what this fitting handles. The male end is 1-1/4 inch at 11-1/2 threads per inch NPT, and the female swivel end is 1 inch at the same thread pitch. The swivel feature on the female side gives you a little rotational flexibility during hookup, which can save some headache when you're working in tight or awkward spots. Steel construction throughout, so it holds up in demanding line work without issue.
Question by: Dustin E on Aug 5, 2025, 4:49 PM
trying to replace a fitting i busted. is this one the straight adapter that goes from a 1-11-1/2 female NPT swivel over to a 1-1/4-11-1/2 male NPT?
Answer by: Customer Support on Aug 7, 2025, 10:44 AM
It’s a straight pipe-to-pipe steel adapter with a 1-11-1/2 female NPT swivel on one end and a 1-1/4-11-1/2 male NPT on the other, so it matches that thread transition and swivel style.
