Low Pressure Hoses

Global MegaVac hose was the world's first flexible, 1/2 bend radius, high temperature return line hose.

Save space with your total system by porting your return line closer to the pump
Excellent vacuum ratings offering resistance to hose collapse while under suction
Offered in sizes up through 4 1/2" to handle all return line applications
