These vinyl nitrile water suction and discharge hose assemblies are used for pumping or vacuuming water in agricultural, construction, mining, waste-hauling, waste-treatment, and petrochemical applications. The hoses' tube, cover, and helical wire reinforcement have been bonded together to create a hose with one homogeneous layer that cannot separate. The tube and cover are made from vinyl nitrile, which provides good resistance to ozone, animal fats, oils, and petroleum. The wire helix reinforcement helps the hose keep its shape when not in use, keeps the hose from collapsing in suction applications, and helps prevent crushing and kinking. Hose assemblies have fittings installed on both ends for connecting the hose to compatible equipment.
