Quick verdict
If your immediate bottleneck is swapping air tools quickly on one or more hoses, the brass quick-connect kit at $10.09 is a low-cost, durable way to add plugs to multiple tools. If you need a long, bendable feed line for pneumatic control or a small robotic system, the $92.30 polyurethane tubing gives you a generous roll with a compact bore to route through tight spaces. The price gap is large, but the two items do not compete for the same connection point.

Where each product wins
The brass kit wins on tool-end convenience
This brass kit gives you spare plugs for multiple tools, and the thread pattern matches common pneumatic tools. The solid brass body resists corrosion in damp shop air, and the industrial interchange (I/M) style is the usual quick-connect pattern for air tools.
The polyurethane tubing wins on reach and flexibility
A long roll of transparent PU tubing gives you continuous runs, and the compact bore bends easily around frames and panels. With a working pressure up to 1 MPa, instantaneous burst pressure to 3 MPa, and a working temperature range of -15°C to +60°C, it suits pneumatic control and robotic applications.
Product notes
10pc Brass Air Hose Fittings 1/4" NPT Male Industrial Quick Connect Plug Coupler
Choose the brass kit when you want one air supply to serve several tools. It includes ten industrial quick-connect plugs in the 1/4" NPT male style, and the brass exterior is made to resist rust and corrosion, so the plugs should hold up in humid shop air. The standard industrial interchange design means it matches the most common pneumatic tool connection style. The practical limitation is that this is the plug side only; to complete the hookup you pair these with matching couplers on your hose or tool side. If you need a long line to get air from point A to point B, this kit won't get you there on its own-it's built for the connection point, not the run.
Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose -Air Chemical Fuel Oil
Pick the polyurethane tubing when your project calls for a long, flexible line. This is a 50-meter roll of transparent PU pipe in a compact 6x4 mm OD x ID size, so it can handle tight routing and repeated bending without creasing. It handles air, water, and lubricating oil, with working pressure up to 1 MPa, instantaneous burst pressure to 3 MPa, and a working temperature range of -15°C to +60°C, making it a solid fit for pneumatic control or robotic systems. The limitation is the opposite of the brass kit: it gives you the run, not the end connections. You'll still need fittings or connectors to attach it to valves and tools, and the 6x4 mm bore is a compact line.
Final choice by use case
Choose the brass quick-connect kit if your air tools are already hooked up to hoses and you want faster changes at the tool end. Choose the polyurethane tubing if you're building a new pneumatic control line or need a long flexible feed through tight spaces. If you're outfitting a system from scratch, the two work together: the tubing carries the air and the brass plugs handle the tool end.
