Question by: Shane G on Nov 11, 2025, 9:20 AM
got a 1-1/4 male nptf port but i need to step it down to 1 female nptf, is that what this bushing does
Answer by: Customer Support on Nov 12, 2025, 8:40 PM
Function-wise, it is a reducer bushing with a 1-1/4-11-1/2 Male NPTF on one side (B1) and a 1-11-1/2 Female NPTF on the other side (B2). Both threads are to SAE J476.

So this is a reducer, right? What exactly does it reduce *from* and *to*?
Answer by: Customer Support on Oct 23, 2025, 6:15 AM
This reducer bushing goes from a Male NPTF thread size of 1-1/4-11-1/2 down to a Female NPTF thread size of 1-11/12.
Question by: Diane P on Oct 16, 2025, 4:48 PM
what's the pressure rating on this bushing, and is 3,000 psi enough for most hydraulic lines running off a mid-size industrial pump?
Answer by: Customer Support on Oct 18, 2025, 9:55 AM
For most mid-size industrial hydraulic systems, 3,000 psi is right in the wheelhouse of standard operating pressure. This bushing is rated to handle up to 3,000 psi dynamic pressure, so as long as your system stays at or below that threshold, you're in good shape. Systems pushing beyond that range would need a fitting rated higher.
