How to inflate an air spring
One way to inflate air springs (mainly used as Guomat shocks) is to use an air tank supply valve with an air hose clamp (just like air hoses are used to inflate tires). Care must be taken to double check the air pressure in the air spring on a regular basis as air slowly seeps out of the bladder through the rubber/ply.
