Product Questions & Answers

got a 3/8 npt port on my setup but the hose end is 1/4 npt. is this the piece that bridges that gap?

Question by: Daryl G on Aug 9, 2025, 6:43 PM

It steps the connection from a 1/4 inch NPT female thread to a 3/8 inch NPT male thread, so it is meant for exactly that kind of size change between components.

Got a hydraulic setup running at 10,000 psi and need to step down from a 3/8" male port to a 1/4" female connection. This the right piece for that?

Question by: Sheila C on Dec 18, 2025, 6:28 PM

That's exactly what this fitting handles. The FZ-1630 is a reducer bushing with a 3/8" NPT male end and a 1/4" NPT female end, rated for up to 10,000 psi. So if you're bridging that size difference in a high-pressure hydraulic line, this is the correct part for the job.

So this is a reducer fitting, right? Will it handle a 10,000 psi hydraulic system without blowing apart?

Question by: Rusty H on Jun 2, 2025, 9:09 AM

Correct, this high-pressure fitting is a reducer and is rated for a maximum operating pressure of 10,000 psi, so it will handle that pressure safely when properly installed.
