Heat Resistant Rubber Tubing

Heat Resistant Rubber Tubing

Heat resistant rubber tubing should be selected for the temperature at the tube wall and the medium passing through it. Silicone is one material option, but compound, reinforcement and wall construction affect the finished tube’s working limits. Pressure and heat must be considered together.

For coolant, heater or air-line connections, identify the fluid, fittings and expected movement. When comparing the 6 mm to 19 mm sizes discussed for this type of tubing, establish whether the measurement is the inside or outside diameter and specify the wall separately. A size label alone does not define pressure capacity.

Outdoor service can add sunlight and ozone exposure, while a machine installation may add abrasion or nearby hot surfaces. Check those conditions for the selected compound and provide suitable routing and support. Inspect the tube and connections for deterioration during maintenance; heat resistance does not imply unlimited life or freedom from production interruptions.
