This 150PSI hot tar and asphalt suction and delivery hose features a specialized high-temperature and oil-resistant inner tube that resists the adhesion and corrosion of high-temperature asphalt and tar, ensuring smooth discharge and preventing clogging. The built-in hard spiral steel wire skeleton, combined with a textile braided reinforcement layer, fulfills both suction and delivery requirements. With a rated working pressure of 150PSI, it prevents collapsing under negative pressure suction and avoids bulging or delamination during high-temperature delivery. The thickened outer cover is highly resistant to high-temperature baking, gravel friction, and outdoor aging. It remains flexible and crack-resistant across a wide range of temperatures. It is widely used in road construction, asphalt mixing plants, and oil depot facilities for the transfer and suction of high-temperature tar and hot asphalt.
