Here's a quick "trick" to improve the piston head/cylinder airseal.

Take the O-ring off the piston head, clean it. Stretch it over the cylinder. Heat it evenly with a lighter/heat source. Hot enough so the rubber changes shape, not so hot that you melt any part of it. Let it cool completely while on the cylinder.

Take it off, clean the ring/cylinder, lightly relube the oring/cylinder, reinstall oring to the piston head.

Compression should be solid between the piston head/cylinder now.

*note: this will not fix an o-ring that fits the piston head very poorly (i.e. too thin/undersized).
