Thermoplastic hose, tubing, and profiles are made by Onyx Hose & Tube Inc. Since high temperatures have an impact on thermoplastics, we have produced these graphs as guidelines for our customers' use.

The physical characteristics of the thermoplastic material are always best at room temperature, which is 68°F or 20°C. We do all of our testing in these circumstances. These materials soften and change physically as the surrounding temperature rises. The recommended working pressure for which the hose or tube was intended is significantly decreased by this modification.

When choosing the right fittings to utilize, careful thought and testing should be done to account for coupling retention.
