When you need hoses, tubing, and fittings, the real question is whether your project needs a long flexible line or durable metal ends. The Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose gives you a continuous run of pressure-rated tubing for air, water, and lubricating oil, while the 12-Pack 1/2" Hose x 1/2" NPTF Male Pipe Thread Hydraulic Hose End Crimp Fittings delivers a set of steel adapters for terminating existing hydraulic hose. They are complementary rather than interchangeable, so your choice depends on where the system starts and ends.
Quick Verdict
If you are building pneumatic controls, robotic air lines, or any run that needs to bend repeatedly, the PU tubing is the complete line solution. If you already have compatible hydraulic hose and need secure connections, the fittings set gives you multiple ends in one purchase. For most buyers, the deciding factor is whether you need the hose itself or only the fittings.

Where the PU Tubing Wins
This is the choice when you want a continuous fluid path that can snake through a chassis or robotic arm. The polyurethane material stays flexible over many bends, and the 1 MPa working pressure with a 3 MPa burst ceiling covers typical shop-air and low-pressure oil applications. It also operates from -15°C to +60°C, so it fits unconditioned industrial spaces. The material bends tightly without creasing, which helps when routing in tight quarters.
Where the Fittings Win
These fittings are for the end of a line, not the middle. Their strength is the combination of a crimp-style connection for hydraulic hose and a pipe-thread port that mates with standard fluid-power components. They are built for petroleum-based fluids, gasoline, fuel, and lubricating oils, and the protection covers help keep the crimp area clean. If your project involves fluid power and you need several identical ends, this set supplies that in one purchase.
Product Notes
Polyurethane Flexible Tubing Pneumatic PU Pipe Tube Hose
This is a long, continuous roll of polyurethane tube, and the 50-meter length is the standout feature for anyone who needs to plumb multiple machines or long runs. The 6x4 mm outer-to-inner diameter is a compact size for pneumatic controls, and the tubing stays flexible enough to route around corners without kinking. It is a practical choice when you have your own fittings and want one continuous line. The limitation is that the roll contains the hose only; you still have to source end connectors and cut exact lengths yourself. Also, the working range of -15°C to +60°C means it is not meant for extreme heat, so keep that in mind if your line runs near hot machinery.
12-Pack 1/2" Hose x 1/2" NPTF Male Pipe Thread Hydraulic Hose End Crimp Fittings
This dozen-piece set is for finishing hydraulic hoses. Each fitting has a crimp-style end that captures a 1/2" ID hose and a 1/2" NPTF male thread for the port connection, so you can assemble twelve terminations without buying extra pieces. The steel construction and protection covers make the set suitable for demanding fluid lines, and the matched pipe thread is common on pumps, valves, and cylinders. The main catch is that the pack does not include hose; you need to supply your own 1/2" ID hydraulic hose for the crimp ends to grab. If your ports use a different thread, these will not adapt without additional parts.
Final Choice by Use Case
Choose the PU tubing when you need a long, flexible line for air, water, or low-pressure oil, and you are comfortable adding your own termination fittings. Choose the hydraulic crimp-fittings set when you already have compatible hydraulic hose and need multiple secure end connections. For a one-piece solution, the tubing is the only product that supplies the hose itself; for finishing existing lines, the fittings set delivers everything in one dozen-piece pack.
