The weight of the tip of the hose lightly lifts up during use.
I pass the unnecessary 15 mm nut through the hose and weigh it instead.
Since it is not a one-touch coupler, I bought it separately.
The glass beads 300 are handy because they can be used normally.
Disassembly Cleaning is easy and easy. I used it when blowing the lower chassis black but it is easy to use. It is better if there is a band because metal fittings with a suction mouth net and hose are easy to come off. I bound it with a wire, but the hose is easy to cut.
I use it for the compressor's cooler cleaning. If you can take the air source, it is possible to clean cleaner than washing with only water pressure. In the winter, however, the washing liquid to be sucked up is frozen, making continuous cleaning impossible. I guess this is the downside. It is a good product.
