Description
The No. 3375 check valve is made of a one-piece cast stainless steel body, with all internal components also of stainless steel. Designed to operate in any position, a sensitive spring has been added to close the poppet automatically. The rubber poppet is fully-formed around a solid steel insert to provide greater strength in commercial applications. Each valve is tested twice for casting integrity and backflow prevention. All valves are 100% American-Made and built to last.
Application
Used for gas and oil applications, including gasoline, hydraulic fluids, diesel fuel, alcohol, kerosene, and mineral oil. (Same as No.375)
