Flexible Joints & Motion Compensators
Engineered motion accommodation for high-pressure, high-temperature duct systems.
RSA flexible joints and motion compensators are designed to absorb displacement within pneumatic ducting systems subjected to thermal expansion, vibration, and structural movement. These components protect upstream and downstream assemblies by reducing transmitted loads while maintaining pressure containment.
Solutions are applied in high-pressure duct systems operating in elevated thermal environments.
Features & Benefits
- Accommodates axial, angular, and parallel offset movement
- Reduces transmitted loads within duct systems
- Maintains structural integrity under extreme pressure and heat
- Lightweight sheet-metal construction
- Multiple joint architectures matched to movement profiles
- Proven in flight-critical pneumatic applications
Available Configurations
Available in multiple joint architectures to match defined movement profiles, load conditions, and installation constraints — supporting both standalone component supply and fully integrated duct systems.
- Diameter range from 1” to 11”
- Pressure capability exceeding 600 psi
- Temperature capability up to 1,200°F
- Bellows ball joints
- Gimbal joints
- Braided bellows (axial growth control)
- Free bellows and link joint designs
- Catalog-qualified or custom-engineered solutions
