These thermoplastic rubber water suction and discharge hose assemblies are used for vacuuming or pumping water in waste-management, construction, agricultural, marine, and manufacturing applications. These hoses stay flexible in cold weather and resist most chemicals used in the agricultural and sanitation industries. The hoses' smooth interior helps keep material from building up in the hose. Their corrugated outer helix improves their abrasion resistance and reduces friction when dragging or maneuvering the hoses on surfaces. The hoses have polyethylene helix reinforcement that helps them keep their shape when not in use and prevents them from collapsing in suction applications. Hose assemblies have fittings installed on both ends for connecting the hose to compatible equipment.
