Fast automatic suction: According to the siphon principle, the copper water head is quickly shaken, the diameter of the oil is quickly enlarged, the work efficiency is improved, and the oil is pumped becomes faster. High quality thick materialThe pump tube is made of PVC, which is safe, environmentally friendly, non-toxic and odorless. The thick material is not deformed and has a longer service life. Copper head suction valve, corrosion resistant, wear resistant, drop resistant, not easy to crack. Product size: The set includes 1 peristaltic pump, the length of the agitator pump is 1.71m, the tube diameter is 18mm, and the tube thickness is 2mm. The length of the copper valve is 6.2 cm. The copper valve and the PVC pipe are firmly connected to each other, with a high degree of tightness, no precious liquid is spilled. Easy to use method: Put the copper head in the bucket and shake it quickly until the water comes out. This fuel siphon hose only needs to be shaken up and down for work. (The liquid you are trying to suck up must be HIGHER than the incoming bucket, the copper head must be held in the liquid.) More UsesIdeal for water, diesel, gasoline and other liquids. Suitable for gasoline siphon pump, drinking water pipe, wine siphon pump, emergency siphon, fuel supply pipe and aquarium fish tank, liquid supply with general pressure. Pump hose-----Fast and safe pumping without electricity, inexpensive, safe, easy. Hand-operated siphon pump Non-return ball made of corrosion-resistant glass. Manual stirring pump for clean settling. Easy transfer of liquids without electricity and manual suction. No spillage Copper valve and PVC pipe are firmly connected, no spillage of precious liquids, lightweight and portable hand pumps. Fast-moving suction head easy transfer from upper containers to lower containers. Quickly move the suction head up and down several times. The liquid then flows independently by negative pressure. The pump tubing pumps liquids quickly and safely - without electricity. Liquid pump tubing The pump hose suitable for water, diesel, gasoline and other liquids and other common liquids, also can be a water changer for your home fish tank. /p> Specifications Material: PVC, copper, glass Valve body material: copper< /p> Colour: Transparent Length: 171cm.

Then vigorously move the suction head up and down several times. 2. The connection end must be inside the liquid. 3. Please note that the flow rate depends on the viscosity of the liquid and the height difference between the two containers.
