Choosing hydraulic hose end fittings for 1/2" hose starts with the end type. Here, the choice is between a female JIC 37° swivel crimp fitting and a male NPTF pipe-thread crimp fitting. Both are new packs for 1/2" hose x 1/2" thread, both are silver, but they differ in the connection end.
Quick verdict: If your hydraulic line depends on JIC 37° flare connections, choose the female JIC swivel pack. If the fitting has to thread into a female NPTF port, choose the NPTF male pipe-thread pack.

Where each product wins
The JIC 37° female fitting wins for flare-type hydraulic connections. Its 37° seat seals against a male flare, and the end rotates for assembly. The NPTF male pipe thread wins when your port is a female pipe thread, because the male NPTF end goes directly into that port.
Product notes
#### 1/2" Hose x 1/2" JIC 37° Female Hydraulic Hose End Swivel Crimp Fitting 12 Pack
This pack provides female JIC 37° swivel ends for hydraulic hose. The 37° seat is the sealing surface, and the threads hold the connection mechanically once the male flare is seated. If your components use JIC flare connections, this is the end type you need. The swivel end is the reason to pick it: it gives you the rotating female half for a flare joint rather than a fixed pipe thread. The limitation is that a female JIC swivel cannot substitute for a male NPTF pipe thread. It will not thread into an NPTF port, so it belongs in a flare-seat system.
#### 12-Pack 1/2" Hose x 1/2" NPTF Male Pipe Thread Hydraulic Hose End Crimp Fittings
This pack uses a male NPTF pipe-thread end, which is the right choice when your hose has to terminate in a female pipe-thread port. The thread end comes with a protection cover, and the carbon-steel body is suitable for fluid-power use with petroleum-based fluids, gasoline, fuel, and lubricating oils in a temperature range of -65°F to 500°F. The reason to choose it is the thread style: a male NPTF end that can go directly into a female pipe port. The limitation is the opposite of the JIC pack: it is a male pipe thread, not a 37° flare, so it will not match JIC flare components. Use it when the port is an NPTF female thread.
Final choice by use case
- For a JIC 37° flare connection with a female end: get the JIC 37° Female Swivel 12-Pack.
- For a male thread that goes into an NPTF port: get the NPTF Male Pipe Thread 12-Pack.
