These PVC (polyvinyl chloride) suction and discharge hose assemblies are used to vacuum or pump water in construction and septic-tank cleaning operations and for general industrial and agricultural applications that require a hose with mild chemical resistance. The hoses are made from PVC, which provides good flexibility and mild resistance to chemicals. They have rigid PVC helix reinforcement that helps them keep their shape when not in use and prevents the hoses from collapsing in suction applications. These hose assemblies have fittings installed on both ends for connecting the hose to compatible equipment.
