Put the piston in it

Find the right M10 Screw to make the piston Long inoff to inject the whole contenant inside the cartridge. Have a look before if the head can go inside the pipe Inox steel is less resistant to bending. Juste have that in mind

You are ready to go !

Be carefull, an Hydraulic Car Jack have a lot of strenght

Now you are ready to inject small plastic part pre-heated in a 1/2" iron cartridge pipe everywhere without electricity
