News Summary

• The MetMo Piston is what happens when you shrink a pneumatic system down to pocket size and machine it from solid brass.
• A precision-machined piston pin slides into an equally precise cylinder block, and the tolerances between the two are so tight that air cannot escape.
• Spin the knurled housing and the piston pin rotates on what MetMo calls an aerodynamic bearing, a thin cushion of air that forms between the pin and the cylinder block.
• The Piston also features a pressure release valve that lets you adjust the drop speed and rebound behavior of the piston.
