【Premium Material】The fuel hand pump is made of high-quality clear anti-static PVC tubing, which is non-toxic, odorless, and not easy to deform. The copper core is corrosion-resistant and firmly connected. 【Practical Size】The total length of the hand siphon pump is 2 m. The outer diameter of the tube is 20 mm and the thickness is 1 mm. Compared with other clamp siphon pumps, a tighter clamping force prevents the brass fittings from falling off. 【Easy to Use Siphon Pump】Put the copper head into the bucket and shake it quickly until the liquid flows out. The liquid you are trying to absorb should be higher than the leaking bucket. The copper head must be kept in the liquid.
