G981 Agricultural Spray hose handles a wide range of wettable powder type chemicals encountered in fertilizer, insecticide, and herbicide spraying (not designed for aromatic hydrocarbons, e.g. xylene).
Higher working pressure and a tube made from a blend of PVC and polyurethaneare the two extra features that the green G981 provides when compared to the yellow G961.
The urethane compound in G981 provides excellent resistance to hydrocarbon based chemicals such as those found in tree spraying and some other applications.
As a general rule of thumb, if the spray comes from a powder, use either G961 or G981, but if the spray comes in liquid form, check the ingredients carefully - G981 may be the best choice.
