Product Overview

• Polyurethane plastic tubing, outer diameter 4 mm, inner diameter 2 mm
• Sold by the meter; can be cut to any length
• Operating pressure up to 10 bar
• Temperature range −40 to +60 °C
• Resistant to oil and many chemicals
• Flexible even at low temperatures

Product Description

This polyurethane plastic hose is suitable for pneumatic, water, and oil lines in laboratory setups and prototypes. With an outer diameter of 4 mm and an inner diameter of 2 mm, it fits standard connections on valves, pressure regulators, and compressors. The tubing is sold by the meter and can be cut to the desired length using simple scissors or a utility knife.

With a maximum operating pressure of 10 bar, the hose can withstand moderate pressure, such as that generated by laboratory air supplies or small vacuum pumps. The material remains flexible and tear-resistant in the temperature range between −40 and +60 °C; it does not lose its elasticity even in cold conditions. Its resistance to oil and many organic solvents makes it durable in workshop environments.

Applications include pneumatic learning projects, water dosing systems in experiments, vacuum setups with diaphragm pumps, or dilution systems for paint sprayers. When assembling larger networks, longer runs must be achieved either by making multiple connections or by cutting the tubing to length from longer sections. Connections are made using crimp fittings or heat-shrink tubing, which must be purchased separately.

Safety Notice

This material is intended exclusively for setup and testing purposes with compressed air, water, or diluted chemicals in laboratories and workshops. It is not suitable for connection to drinking water lines or natural gas systems. When operating compressed air systems or designing them, a qualified electrician should be consulted to verify compliance with safety regulations.
