Question by: Harvey M on Mar 31, 2026, 5:19 PM
got a 2 inch nptf port but i need to step it down to 1-1/2. is this the right bushing for that
Answer by: Customer Support on Apr 2, 2026, 6:46 AM
For stepping down a 2-11-1/2 male NPTF thread to a 1-1/2-11-1/2 female NPTF thread, this reducer bushing matches that exact setup. Both ends are NPTF and built to SAE J476 thread specs, so it is meant to mate up cleanly in that size change.
Question by: Ray B on Jun 18, 2025, 8:32 PM
What size threads are we talking on each end of this bushing, is the bigger end the male or the female?
Answer by: Customer Support on Jun 20, 2025, 6:30 PM
The larger end carries the male NPTF thread, sized at 2-11-1/2. The smaller end is the female NPTF, sized at 1-1/2-11-1/2. Both ends conform to SAE J476, so you're working with a standard tapered fuel thread profile on each side. The bushing steps down from that 2-inch male connection to accept a 1-1/2-inch female fitting.
