Product Information This economical pump combines the best abilities of a pressure pump with those of a vacuum pump. When the bottom nozzle is connected to a container, it can be used as a vacuum pump. When the side nozzle is connected, it becomes a pressure pump. The “two-way” piston provides better sealing than bicycle pumps do. Cylinder is made of seamless stainless steel. Size: 20 cm L x 2.25 cm dia.  Tell a Friend about this item
