LEGO® pneumatic parts add air-powered movement to Technic models, machinery and custom mechanical builds. This collection includes pneumatic cylinders, switches, pumps, air tanks, hoses, air motors and connectors used to create lifting functions, grabbers, moving arms and other working systems.

Unlike electric Technic systems, pneumatic mechanisms use compressed air to create controlled mechanical motion. For the wider range of structural and mechanical components, explore our LEGO® Technic parts collection.

LEGO® Pneumatic Parts for Air-Powered Builds

LEGO® Technic pneumatic systems are commonly used in cranes, excavators, loaders, trucks, robotic arms and other builds where realistic lifting, pushing or extending movement is required.

  • Pneumatic Cylinders: Linear actuators used to lift, push, extend and retract moving sections.
  • Pneumatic Switches & Valves: Control the direction and flow of air through the system.
  • Pumps: Generate the air pressure needed to operate cylinders and other pneumatic elements.
  • Air Tanks: Store compressed air to provide a more consistent supply of pressure.
  • Air Motors: Convert air pressure into rotational movement for mechanical functions.
  • Hoses & Connectors: Carry air between pumps, valves, cylinders and other pneumatic components.

How LEGO® Technic Pneumatics Work

A pneumatic system moves air through flexible hoses to cylinders, valves and other components. Pumps generate pressure, switches control airflow and cylinders convert that air pressure into linear movement.

This makes pneumatics useful for mechanisms that need smooth lifting, pushing or extending actions without relying on an electric motor for every movement.

Common Uses for LEGO® Pneumatic Systems

  • Cranes: Raise and lower booms, lifting arms and grabbers.
  • Excavators & Loaders: Operate buckets, arms and articulated tools.
  • Robotic Arms: Create controlled extending, lifting and gripping movements.
  • Industrial-Style Machinery: Build presses, lifting mechanisms and moving mechanical assemblies.
  • Technic MOCs: Add realistic air-powered functions to custom engineering projects.

Pneumatic Cylinders, Pumps & Switches

Pneumatic cylinders are the main moving elements in many Technic air systems, while pumps provide pressure and switches direct airflow between different functions. Combining these components allows builders to create multi-function mechanisms with independent moving sections.

Use LEGO® hose pieces to route air between components and Technic pins and connectors to secure surrounding mechanical assemblies.

Build Strong Pneumatic Mechanisms

Pneumatic components usually operate inside a larger Technic structure. Support cylinders, pumps and moving sections with Technic beams and liftarms or Technic bricks to create rigid frames and secure mounting points.
