Hydraulic hose adapter

This Eaton 2046-4-4S hydraulic hose adapter connects a female NPT thread to a female NPSM swivel thread. Both threads measure 1/4 inch minus 18. The carbon steel body has a trivalent chromate zinc finish and a length of 1.12 inches. It is rated for a maximum working pressure of 4500 PSI.

Installers needing a straight SAE/JIC 37-degree

Technicians who require a straight hydraulic fitting with these exact thread types and pressure rating will use this adapter. It does not suit applications that demand a different thread standard, an elbow shape or a higher pressure rating. Buyers needing other configurations should look at alternative fittings.

SAE/JIC 37-degree flare standard

The adapter conforms to the SAE/JIC 37-degree flare specification. This single standard determines whether the fitting will seal correctly in the intended hydraulic system. Verify that the mating components share the same flare angle before purchasing.

Questions about this item

What thread must the existing hose or port have to accept the 1/4-18 FNPSM swivel on this adapter?

The mating side needs a 1/4-18 male NPSM thread so the swivel nut can seal against the 37-degree flare seat.

Will the 1/4-18 FNPT end thread directly into a legacy 1/4 NPT port on older equipment?

Yes, the 1/4-18 FNPT female thread matches standard 1/4 NPT male pipe threads found on many older hydraulic components.

How can I confirm the 4500 PSI rating is holding after installation?

Pressurise the circuit to working pressure and check the trivalent chromate zinc finish for any weeping at the 37-degree flare and NPT joints.
