Pump for Cylinders
Being a one hand pump, it can be operated by one hand only, so you have your other hand free to hold the cylinder in place. Maximum vacuum capacity 0.25 bar (approximate), so this pump can draw no more than 75% of air out of a cylinder which is relatively body safe.
Of course as with all vacuum toys: listen to your body and don’t overdo it, build up slow. Can also be used on LAPD, Dr Kaplan and Boston Pump cylinders Also suitable for wet pumping "
