PVC and PA (nylon) hose characteristics

Working pressure – temperature relation for PVC hoses

Recommended working temperature ranges from -20°C up to +60°C. A rise in temperature above +20°C causes considerable decrease of bursting pressure and at the same time allowable working pressure.

Example: 11.25 bar (100%), working pressure at +20°C, about 6 bar (55%) at +40°C.
