Aries HPI-1-2-25-FH Hydra-Pneumatic Cylinder

The Aries HyperCyl HPI-1-2-25-FH Hydra-Pneumatic Cylinder is a self-contained inline power unit that combines air actuation with an oil-driven pressure stage to deliver high force from a compact package. It features a 2.00‑inch stroke and an EE 1/8" NPT port configuration. For this model, the piston delivers about 22.34 pounds of force per psi of air pressure, enabling strong, repeatable actuation from standard shop air (30–100 psi typical) without external hydraulic lines. Hydra-pneumatic cylinders are designed for assembly and forming tasks and excel in punching, riveting, bending, and forming where a small footprint and high force are advantageous. This HPI inline series cylinder embodies the self-contained power source concept promoted by HyperCyl, offering straightforward two-valve operation and elimination of hydraulic lines for reliable, high-force performance in metal-forming applications.
