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.
If you're planning or upgrading your pneumatic setup and need guidance on tubing or fittings, SHPI is here to help.
