Green Pump: Is about 12" tall from the base of the pump to the tip of the nozzle. The inside piston has 2 O Rings in tandem for the best seal. Purple Pump: Is about 11.25" tall from the base of the pump to the tip of the nozzle. The piston has a single O Ring. PLEASE NOTE: We used to stock the Qualatex pumps for many years, but as of 2025 they are no longer available to us. The pumps that we stock are made in the same style, and function the exact same way. They may not be a perfect match to the ones pictured, but they are practically the same in form and function.
