Choosing between hose fittings starts with a question about the connection on the end of your line. Air tools and compressor hoses usually pair with quick-connect plugs that snap into couplers. Hydraulic equipment often needs swivel crimp ends that lock the hose into a flare fitting. In the hoses and tubing fittings aisle, the two kits here sit on opposite sides of that split: one is a brass plug set for pneumatic work, the other is a hydraulic crimp set for fluid power lines.
Quick verdict
Go with the brass quick-connect plug coupler kit if you're setting up air tools, compressor hoses, or any standard pneumatic connection. Go with the JIC hydraulic hose end swivel crimp fittings if you're assembling hydraulic hoses and need a female swivel end on each fitting.

| 12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings | $43.69 | 12 pieces | 3/8" JIC 37° female swivel crimp | Hydraulic hoses with 3/8" I.D. |
Where each set wins
The brass plug kit wins on price, material, and the familiar I/M-style interchange. The solid brass construction gives it corrosion resistance in damp shop air, and the plugs are enough to keep several tools ready at the compressor.
The hydraulic crimp set wins on bundle size and the connection family for fluid power. Its female JIC 37-degree swivel ends are made for hydraulic hose and can handle petroleum-based fluids, gasoline, fuel, and lubricating oils.
Product notes
10pc Brass Air Hose Fittings 1/4" NPT Male Industrial Quick Connect Plug Coupler
This set gives you industrial quick-connect plugs in solid brass, so each line gets a corrosion-resistant male end that snaps into standard I/M-style pneumatic couplers. That makes it easy to switch tools at the compressor without turning off the air supply. The listed price is $10.09 for the full kit, which puts it in the lower-priced lane for shop air systems. The trade-off is the connection family: this is a male NPT plug meant for pneumatic hoses and tools, not a hydraulic swivel end. If your project uses a hydraulic hose end, these plugs won't take that fitting. It's the right tool for air lines and the wrong one for fluid-power hoses.
12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings
These are hydraulic hose end fittings with a female JIC 37-degree swivel end on each piece and a straight shape for stable connections. They're designed for hydraulic hose, and the fittings handle petroleum-based fluids, gasoline, fuel, and lubricating oils. The listed price of $43.69 covers the full bundle, which is the higher outlay of the two kits. The limitation is that these are not quick-connect air plugs, so they won't fit a standard pneumatic coupler. They make sense when your work involves fluid lines rather than compressor tools.
Final choice by use case
For pneumatic setups, the brass plug kit is the practical match, on both connection type and budget. For hydraulic repair or assembly, the JIC crimp set provides the swivel female ends and fluid compatibility that pneumatic plugs can't. If you run both kinds of equipment, you may end up needing both; choose the one that matches the hose system you're working on today.
