1.Make sure that the cutting surface of the pipe is vertical. Please insert the tube into the bottom before use.
2.When inserting the pipe into the joint, it must be inserted into the end, otherwise there may be a leak.
3.After plugging in, try to pull the tube, if you cant pull it out, it means it has been connected.
4.When loosening the tube, first confirm that there is no pressure in the tube, and then evenly press the end cap to the bottom.
