Nylon fittings are made from high quality type 6 virgin resin. Acceptable for use at working pressures up to 150 PSI at normal room temperatures. At very low pressures, temperatures can approach 175° F with no degradation.
Nylon is resistant to a broad range of chemicals including most agricultural chemicals, ammonium compounds, detergents, diesel fuel, ethanol, gasoline, hexane, magnesium sulphate, most sodium compounds, trichloroethylene and zinc sulphate.
Nylon fittings should not be used with acid-based fertilizers, bromine, chlorine, fluorine, hydrochloric acid, iodine, nitric acid, phosphoric acid, sulfuric acid and xylene.
