When you're working with hoses and tubing fittings, the first fork in the road is knowing whether you need fittings that attach a hose to a machine or caps and plugs that seal off unused ports. Buy the wrong type and you'll either have hoses that can't connect or open fittings that leak fluid. The two kits here take opposite approaches: one gives you a set of hose end fittings for a specific connection, while the other supplies a broad assortment of caps and plugs in common hydraulic sizes. Which one belongs in your toolbox depends on whether your next job is building a hose assembly or protecting hydraulic ports.
Quick Verdict
If your next job is assembling or repairing hydraulic hoses, the $43.69 fitting set is the direct, lower-cost choice. If you need to seal and protect hydraulic ports, the $89.99 cap-and-plug kit is the broader solution, and the $46.30 price gap buys far more size options.

Where Each Product Wins
The fitting set wins when the task is joining hose to a threaded port. It gives you a straight, stable connection and enough matching pieces to handle multiple assemblies in one session. The cap-and-plug kit wins when you need to close off ports and keep contaminants out. It protects a wide range of connection sizes with one assortment, so you don't have to hunt for individual caps and plugs as jobs come up.
12pcs 3/8" Hose x 3/8" JIC 37° Female Hydraulic Hose End Swivel Crimp Fittings
This set is built for a specific connection: a 3/8" I.D. hydraulic hose ending in a 3/8" JIC 37° female swivel. The straight fittings keep the assembly stable, and the included protective covers are handy for storing finished hoses. They are suited to petroleum-based fluids like gasoline, fuel, and lubricating oils, which makes them a good fit for general hydraulic work. It's a practical choice when you have multiple identical hose assemblies to make. The trade-off is the narrow scope: this is not a general assortment, so you are covered for this one configuration rather than a whole range of sizes. If your job stays within that size, the set gives you enough pieces to keep a few spares around.
144pc JIC & ORFS Master Industrial Hydraulic Cap & Plug Hose Tube & Pipe Fitting Kit
This master kit supplies a large assortment of caps and plugs for JIC and ORFS connections. Stainless steel construction is meant to handle vibration, pressure spikes, and outdoor conditions, and the dash size coverage makes it useful across a range of ports and lines. The caps and plugs are designed to keep fluids from escaping and contaminants from entering, which is a solid foundation for a reliable hydraulic system. It's a strong fit for shops that service automotive, industrial, or aerospace equipment and want one box of sealing parts at the ready. What it doesn't do is build hose ends; this is a cap-and-plug assortment, not a hose end fitting set. If you are assembling a hose from scratch, you will need separate hose end fittings, but for sealing duties this kit has you covered.
Final Choice by Use Case
Choose the fitting set when you are manufacturing or repairing a hydraulic hose assembly and want a straightforward, lower-priced set. It is the more focused purchase for a specific JIC hose end job. Choose the cap-and-plug kit when you need to protect a variety of hydraulic ports and prefer a comprehensive stainless steel assortment. If your work involves both building hoses and sealing ports, the cap-and-plug kit is the broader long-term investment, while the fitting set covers the immediate hose assembly need.
