Choosing the right hose or tube fitting isn't just about thread size. You may be sealing unused hydraulic ports, attaching an end to a hydraulic hose, making air tools easy to connect, or running a long flexible line to a moving part. These are different jobs, and each one calls for a different part. The four options here split cleanly by task: a fitting protection assortment, a pack of hose ends, a set of plugs, and a roll of tubing. The right purchase depends on what you're connecting, not just on which box is bigger.
Quick Take
For protecting open hydraulic ports, the protection kit gives you the widest coverage. For terminating a hydraulic hose, the crimp fitting pack is the focused choice. For air tools, the plug set keeps tool changeovers simple. For a long, bendable line, the tubing roll covers the distance.

Product Notes
144pc JIC & ORFS Master Industrial Hydraulic Cap & Plug Kit
At USD 89.99, this assortment is the broadest protection option here. It includes caps and plugs in dash sizes 4, 6, 8, 10, 12, and 16, and it covers both JIC and ORFS styles, so it suits a shop with a mix of hydraulic fittings. The stainless steel construction supports leak prevention, keeping fluid in and debris out. The limitation is that it's a protection kit, not a hose-end kit: it won't form a new connection between a hose and a component. If your job is sealing ports that are already in place, this kit has the sizes. If you need to build out a hose line, you'll want a dedicated hose-end fitting.
1/2" Hose x 1/2" JIC 37° Female Hydraulic Hose End Swivel Crimp Fitting 12 Pack
This 12-pack is built for a single, repeatable task: putting a 1/2-inch female JIC 37-degree swivel end onto 1/2-inch hydraulic hose. At USD 45.99, you get twelve identical fittings, enough to standardize several assemblies without mixing sizes. High-strength, corrosion-resistant coated steel and the 37° seat design line up with common JIC flare sealing. The trade-off is narrow scope: every piece is the same size and configuration. If your system needs a different hose size, a different flare angle, or a different end style, none of these twelve will work. This is a quantity buy for a known 1/2-inch JIC application.
10pc Brass Air Hose Fittings 1/4" NPT Male Industrial Quick Connect Plug Coupler
At USD 10.09, this is the least expensive of the four listed options, adding 1/4-inch NPT male quick-connect plugs to air tools or hoses. The plugs are solid brass and use the standard industrial interchange (I/M) style common on air tools. Having ten plugs means you can equip several tools at once rather than moving one fitting around. The limitation is that these are plugs only; they're meant to pair with a separate quick-connect socket, so the set doesn't include the female receptacle side. The 1/4-inch NPT male thread and I/M style are also specific, so this fits that common segment of air setups rather than every air line.
Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose -Air Chemical Fuel Oil
At USD 92.30, this 50-meter roll of transparent polyurethane tubing takes a different approach: instead of fittings, you get a continuous 6x4 mm line for air, water, or lubricating oil. The material is highly transparent, flexible, and kink-resistant, with an operating pressure range of 0 to 1 MPa and a working temperature range of -15°C to +60°C, making it useful for air control or robotic systems. The limitation is the fixed 6x4 mm outer-to-inner diameter and 50-meter length. If you need a larger bore for higher flow or a shorter exact run, this roll won't match. It's raw tubing, so connecting it to ports, valves, or tools is handled separately.
Final Recommendation by Use Case
To protect open hydraulic ports across a range of fitting styles, start with the protection assortment. For hydraulic hose termination, the crimp fitting pack is the matched set. For air-tool hookups, the plug set handles the connection side. To run a long, flexible line, the tubing roll covers the distance.
