Choosing between hydraulic hose end fittings starts with matching the hose I.D. and the end connection style. The 12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings is built for 3/8" I.D. hose with a 3/8" JIC 37° female swivel end. The 12-Pack 1/2" Hose x 1/2" NPTF Male Pipe Thread Hydraulic Hose End Crimp Fittings targets 1/2" I.D. hose with a male NPTF pipe-thread end. Both are 12-piece sets in new condition with silver fittings and a money-back or replacement after-sales option, but the size and thread differences are what determine the right choice.
Quick verdict
If your system uses a 37° female JIC swivel connection, the 12pcs JIC set is the one to pick. If your lines end in a male NPTF pipe thread, the 12-Pack NPTF set is the match. The listed-price spread between them is USD 1.70. The right match for your hose I.D. should guide the decision.
Listed price and connection comparison
| Option | Listed Price | Price Bar | Hose End |
|---|---|---|---|
| 12pcs 3/8" JIC 37° Female Swivel Crimp Fittings | USD 43.69 | 3/8" hose x 3/8" JIC 37° female | |

Where each option wins
The 3/8" JIC set wins when your setup already uses JIC 37° female swivel ends. It pairs a straight 3/8" I.D. hose end with a 3/8" JIC 37° female swivel, and the connector type is hydraulic hose fittings. It also comes with a protection cover and is in new condition.
The 1/2" NPTF set wins for hoses that terminate in a male NPTF pipe thread. Its end style is NPTF male thread and its connector type is adapter. The set uses premium carbon steel and covers a temperature range from -65°F to 500°F, giving it an edge for fluid-power work that sees broad temperatures.
Product notes
12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings
This set is centered on 3/8" I.D. hydraulic hose and a 3/8" JIC 37° female swivel end. The straight shape and protection cover are part of the design, and the bundle includes 12 pieces, giving you enough fittings to handle several connections in one order. The item is in new condition with a money-back or replacement after-sales option. The main limitation is the connection style: if your lines are 1/2" I.D. or need a male NPTF pipe-thread end, these fittings will not match the configuration described in the title. It makes sense mainly for systems that truly need the JIC 37° female swivel end.
12-Pack 1/2" Hose x 1/2" NPTF Male Pipe Thread Hydraulic Hose End Crimp Fittings
This pack is made for 1/2" I.D. hose with a 1/2" NPTF male pipe-thread end. Its end style is NPTF male thread and its connector type is adapter. The set uses premium carbon steel and covers a temperature range from -65°F to 500°F, which can be useful when the hydraulic fluid or surrounding environment moves across a wide temperature range. The limitation is that this is a male NPTF configuration for 1/2" hose, so it will not suit 3/8" I.D. lines or JIC 37° female swivel ends. Pick this pack when your system is built around 1/2" pipe-thread connections.
Final choice by use case
- For 3/8" I.D. hose with a 37° female JIC swivel: choose the 12pcs 3/8" JIC 37° Female Swivel Crimp Fittings at USD 43.69.
- For 1/2" I.D. hose with a male NPTF pipe-thread end: choose the 12-Pack 1/2" NPTF Male Pipe Thread Crimp Fittings at USD 41.99.
- If you want the temperature range covered by the 1/2" set, choose the NPTF pack only when your hose size and thread type line up.
