It resists mild chemicals, low-pressure service, and water. That behavior comes from the compound itself: Red Rubber, Smooth Finish is widely chosen for reliable water and air sealing, easy cutting and fabrication in the field. Applications involving ozone and direct sunlight or petroleum oils and fuels call for a different compound.

Typical settings include HVAC ductwork, low-pressure air service, and general plant maintenance.
