LIQUID-TUFF UL listed Hi-Low Temperature LFMC is a high performer in both high and low temperature conditions. Conduits should be carefully selected based on their applications, which can affect performance. Operating temperatures should be taken into consideration when installing in areas that will have extreme high temperatures or low temperatures over extended periods of time. Some examples would be rooftops, solar installations or other areas of direct sunlight. Conduits not suited for these applications may have shortened service life due to degradation of the material.
