Behind a Concert Stage: How Pneumatic Systems, PU Tubing, Nylon 12 & Quick Fittings Make It Work

“Let's go to a concert!”

In recent years, concerts have practically become a national pastime. From dramatic lighting, moving stage platforms, to the emotional energy of a stadium-wide singalong—concerts create moments we fully immerse in.

But—have you ever wondered…
When you finally walk into the venue with excitement, have you ever thought:

  • How is a concert stage built?
  • How do indoor and outdoor stages differ?
  • What system ensures every movement is precise, safe, and flawless?

A concert stage is essentially a temporary industrial automation system

From setup → rehearsal → the live show, pneumatic systems play an irreplaceable role throughout the entire process.

Every phase of a concert—from building the stage to the final performance—requires different pneumatic equipment.

For outdoor stages that must be constructed from scratch, the pneumatic system takes on completely different tasks at each stage.

1. Stage Setup: Pneumatic Tools Do the Heavy Lifting

During truss assembly, LED wall installation, and frame construction, crews rely heavily on pneumatic impact wrenches, cutters, and nailers.

They need hoses that are:

  • Resistant to foot traffic and dragging
  • Hard to rupture
  • Stable in airflow and volume
Commonly Used Hose Assemblies:

Reinforced PU Air Hose Assemblies

Hybrid PVC Air Hose Assemblies

2. Rehearsal & Adjustment: Platforms, Lifts and Mechanisms Move Into Action

Lifts, trapdoors, rotating stages, and moving platforms all rely on pneumatic cylinders and valves.
Tubing requirements include:

  • Pressure resistance and dimensional stability
  • Flexibility for repeated movement
  • High sealing performance and quick installation
Tubing / Fitting Key Characteristics
Nylon 12 Tubing (PA12 Tubing) High pressure stability, minimal deformation
Polyurethane Tubing Ester Flexible, oil/abrasion resistant
Polyurethane Tubing Ether Hydrolysis-resistant, suitable for moisture
One Touch Fittings (Push-in Fittings) Excellent sealing, quick and tool-free installation
Speed Controllers Controls cylinder motion speed
Check Valves Prevents backflow, adds safety

At this stage, the durability of the tubing and the sealing performance of the fittings directly determine the safety of the stage mechanisms.

3. Live Performance: 80% of Stage Effects Are Pneumatically Driven

Rising, dropping, firing, pushing, inflating — Most of these effects rely on pneumatic power.

So what types of tubing and fittings are typically used to support these stage effects?

Stage Effect Pneumatic Requirement Common Tubing
CO₂ Jet Low-temperature flexibility Reinforced PU Air Hose
Confetti Shooters Medium–low pressure, fast response PU Tubing Ester
One Touch Fittings
Air Ram Launcher High-pressure impact R7 / R8 Hydraulic Hose
Inflatables Continuous airflow PU Tubing Ester
Nylon 12 Tubing
One Touch Fittings
Speed Controller
Check Valve
Stage Lifts Stable control Using the appropriate tubing for each section, such as:
R7 / R8 Hydraulic Hose
Reinforced PU Air Hose
Nylon 12 Tubing

Why Pneumatics Instead of Pure Electric Systems?

The reasons are simple:

  • Faster response for instant effects
  • Safer failure mode than electrical systems
  • Fast setup/teardown for touring productions

Next time—when you're scrolling your phone before the show starts, take a second and imagine how many systems are moving beneath the stage.

You'll realize that every lift, burst, push, and inflation is powered by a precise and reliable pneumatic system.
