A ferrule tee check valve for a piston filling machine is provided to assemble and disassemble easily and quickly, and to clean conveniently by engaging a projection of a check valve body with a recessed groove of a spring support bar and contacting a packing to a seat surface. A ferrule tee check valve includes a suction check valve and a discharge check valve easily assembled and disassembled in a ferrule tee(1), a ferrule hose coupling(5), a ferrule nozzle(6) and a ferrule packing inserted to a ferrule part of a cylinder(7) and fixed by a clamp band(10). Contents are sucked into the cylinder through the suction check valve of the ferrule hose coupling with suction of a piston(8), and charged in a container through the discharge check valve and the ferrule nozzle with compression of the piston. The suction check valve is combined with the ferrule tee, and composed of a suction check valve body, a check, a compression spring and a spring support bar. Contents are moved into the cylinder by releasing the compression spring with suction stroke of the piston, and counter flow of contents is restricted by contacting a packing to a seat surface of the suction check valve body with compression stroke of the piston.
