Choosing hoses tubing fittings for a hydraulic system usually comes down to hose size and end style. You can have the right thread angle and still end up with the wrong fitting if the bore doesn't match your hose I.D. or if you need a male end when the kit only contains female swivels. These four JIC 37° multi-pack sets cover 1/4-inch, 3/8-inch, 1/2-inch, and 3/4-inch work, with prices that climb as the size increases. The real decision is whether you want a 12-pack of female swivel ends or a 10-pack of fixed male ends.
Quick take
If the lowest listed price matters for 1/4-inch hose, the 12-piece female swivel set is the clear pick. For 3/8-inch and 1/2-inch female connections, the two mid-size 12-packs are close in price and both include protection covers. For larger 3/4-inch male terminations, the carbon steel 10-pack is the one that matches that job.

Product notes
12x Hydraulic Fittings 1/4" I.D. Hose x 1/4" JIC 37° Female w/ Protection Cover
The 1/4-inch set gives you 12 female swivel crimp fittings sized for 1/4-inch I.D. hose, with a 37° JIC seat and a protective cover over the end. The straight fitting shape is described as improving connection stability, and the set is suitable for petroleum-based fluids, gasoline, fuel, and lubricating oils. If you're starting a small hydraulic repair kit or need spares for compact equipment, this is the most economical entry point in the group. The limitation is the narrow size range: this kit is made for 1/4-inch hose and a 1/4-inch female end, so it won't cover 3/8, 1/2, or 3/4-inch lines.
12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings
This 12-pack moves you up to 3/8-inch hose while keeping the same female JIC 37° swivel layout. The straight design helps keep the connection stable, and each fitting includes a protection cover, which is useful when you're storing spare ends or carrying them to a job. It sits in the middle of the size range and gives you a full dozen pieces for common mid-size hydraulic lines. The trade-off is the end style: these are female swivel fittings only, so a 3/8-inch male JIC end is not included in this pack.
1/2" Hose x 1/2" JIC 37° Female Hydraulic Hose End Swivel Crimp Fitting 12 Pack
The 1/2-inch kit is the largest female swivel option here, with 12 fittings matched to 1/2-inch I.D. hose. The high-strength, corrosion-resistant coated steel and the 37° female seat create a seal through line contact between the male flare and the female cone seat, which is the standard behavior of a JIC connection. This makes it a practical fit for hoses that run to pumps, valves, or cylinders. The limitation is that it stays in female-swivel territory for 1/2-inch hose only; if your system needs a 1/2-inch male end or a different size, you'll need to look elsewhere.
10-Pack 3/4" Hose x 3/4" Male JIC Hydraulic Fittings, Carbon Steel
The 3/4-inch set takes a different approach: it uses fixed male JIC ends instead of female swivels. Made from carbon steel and finished with an anti-rust zinc plating, the fittings are built to SAE J514 and designed for high-pressure connections. The solid male end avoids hose torsion during installation, which can reduce fluid leakage on larger equipment. It's aimed at agricultural, construction, and industrial hydraulic systems as replacement fittings. The limitation is the count: you get 10 pieces instead of 12, and this kit is specific to 3/4-inch male JIC terminations rather than female swivels.
Final recommendation by use case
- For a 1/4-inch hose setup where the lowest listed price is the priority, the 12x Hydraulic Fittings 1/4" I.D. Hose x 1/4" JIC 37° Female set at $30.99 gives you a full dozen female swivel ends.
- For 3/8-inch hose with female swivel ends and protection covers, the 12pcs 3/8" Hose x 3/8" JIC 37° Female set at $43.69 is the matched choice.
