What is the maximum working pressure of the PUSH-IN Polyamide Hose TB 66 for Lubrication Systems at 60°C (correction factor 0.58)?

The maximum working pressure of the PUSH-IN Polyamide Hose TB 66 for Lubrication Systems at 60°C is the nominal maximum working pressure multiplied by the correction factor 0.58. For example, if the nominal maximum working pressure at +20°C (correction factor 1.00) is 16 bar, then at 60°C it would be 16 bar × 0.58 = 9.28 bar. If you provide the hose's nominal working pressure at +20°C, I will calculate the exact value at 60°C.

How does the PUSH-IN Polyamide Hose TB 66 for Lubrication Systems perform at temperatures above 80°C and are there recommended limits or derating factors beyond +80°C?

The PUSH-IN Polyamide Hose TB 66 for Lubrication Systems is rated for operation from 0°C to +100°C. Above +80°C performance must be derated: the manufacturer provides pressure correction factors up to +80°C (20°C/1.00, 30°C/0.83, 40°C/0.72, 50°C/0.64, 60°C/0.58, 70°C/0.52, 80°C/0.47). This means maximum working pressure should be reduced progressively with temperature (e.g., at 80°C allowable pressure is 47% of the 20°C rating). While the hose’s material allows use up to +100°C, no specific correction factors beyond +80°C are listed here, so you should apply caution and consult the manufacturer for certified derating values or limits between +80°C and +100°C before sustained operation at those temperatures.
