got a 5/8 tube line I need to cap off on a hydraulic system running around 4,500 PSI, this gonna hold up to that?

Answer by: Customer Support on Jun 2, 2025, 6:28 AM

At 4,500 PSI you're well within the rated limit. This cap nut is rated up to 5,000 PSI dynamic pressure, so that application falls comfortably inside its range. It uses a female JIC SAE 37-degree flare connection with a 7/8-14 thread, which is the standard fitting for 5/8 OD tube lines. Straight steel construction handles that kind of working pressure without issue in most hydraulic circuits.

got a 7/8-14 JIC port i need to cap off, is this the right one for that

Answer by: Customer Support on Jul 30, 2025, 12:52 PM

For a 7/8-14 female JIC SAE 37 degree flare connection, this cap nut matches that thread and flare style. It is also listed for tube OD 5/8, so it lines up with a standard size 10 JIC setup.
