The main difference between hydraulics and pneumatics lies in the medium used for power transmission: Hydraulics uses fluids, allowing for higher force and precision but can be slower and require more maintenance. Pneumatics uses compressed air, which enables faster movements and simpler systems but with lower force and precision.

Sagroparts.com provides a wide range of products in both hydraulics and pneumatics:

Hydraulics: Hydraulic cylinders, hydraulic pumps, valves, hoses, couplings, and filters.
Pneumatics: Pneumatic valves, air cylinders, regulators, adapters, tube fittings, bushings, silencers, and seals.
