About PVC hoses

PVC hose carries compressed air, water and oil-bearing media wherever a flexible, low-cost line is enough and fixed pipework would be overkill. The group is rated for operating temperatures from -20 °C to 60 °C and runs from bulk hose on the roll to made-up assemblies with a connection thread.

What matters when choosing

• Inner and outer hose diameter: the bore sets the air volume, the difference to the outside diameter sets the wall thickness. The range runs from 6.2x4 to 17.6x13 mm.
• Pressure rating: the permitted pressure is stated per item as max. operating pressure at 23 °C and falls as the bore grows. On the PVC special pneumatic hoses it drops from 40 bar at Ø 6.2x4 to 28 bar at Ø 17.6x13.
• Construction: cover, core and reinforcement separate the types. Versions braided with impregnated special fabric take higher pressures, soft PVC versions stay flexible in the cold.
• Operating temperature: minimum -20 °C to -15 °C and maximum 60 °C. For outdoor runs or cold stores, check the lower figure first.
• Length and routing: hose length, roll length and minimum bend radius decide how the hose is cut and how tightly it can be routed. Made-up items are available with G 3/8 male or G 1/2 male.

Typical applications

• Compressed air supply to tools and workstations in workshops and assembly areas
• Cooling, flushing and service water lines on machine tools
• Oil and grease carrying lines using the oil resistant soft PVC version
• Retrofitting and extending existing lines cut from the roll
• Moving hose runs on machinery where frequent bending cycles occur

The 110 items in this group come from production in Germany, France, Italy, Greece and Poland. Operating temperature is quoted as -20 °C to 60 °C, and the oil resistant versions are also largely resistant to salt solutions, dilute acids and alkalis.
