Constructed from stainless steel, the Danfoss / Eaton Everflex NNJ-4-316 is a JIC female swivel nut designed as a spare part replacement within the Everflex NNJ Series hose assembly system. The 316-grade stainless steel construction offers reliable corrosion resistance in demanding hydraulic environments where standard carbon steel hardware would be unsuitable.
As a swivel nut, this component allows for rotation during assembly, simplifying installation and reducing the risk of hose twist. It is available across a range of sizes, making it a practical stocking item for maintenance and repair applications where NNJ Series fittings are in service.

Question by: Frank S on Jan 30, 2026, 8:47 PM
Is this nut specifically for the NNJ Series, or would it work on other Everflex fittings too?
Answer by: Customer Support on Feb 1, 2026, 2:20 PM
Built strictly as a spare part for the Everflex NNJ Series hose assembly system, so it fits that line and that line only. If you've got other Everflex series running on your equipment, you'd need to match those separately. For NNJ Series assemblies, though, this is the correct replacement nut.

What kind of hydraulic environment is this nut best suited for?
Answer by: Customer Support on Sep 4, 2025, 1:54 PM
Being made of 316 stainless steel, it's especially good in hydraulic systems where you need really reliable corrosion resistance. Places where standard carbon steel just won't cut it.
