Flexible membrane component in gas bladder/piston systems that expands and contracts to transfer pressure or displace fluids.
The bladder body is a critical elastomeric component within gas bladder or piston assemblies, functioning as a flexible, sealed membrane that undergoes controlled deformation under gas pressure. It separates gas and fluid chambers, enabling energy storage, pressure regulation, or fluid displacement through volumetric changes. Engineered for cyclic fatigue resistance and minimal gas permeation, it maintains system integrity in pneumatic, hydraulic, or accumulator applications.

To act as a flexible barrier that expands/contracts with gas pressure to transfer energy, regulate pressure, or displace fluids in systems like accumulators or actuators.
Based on operating conditions: NBR for oil resistance, EPDM for water/steam, FKM for high temps/chemicals, with reinforcement for pressure durability.
Common causes include fatigue cracking from cyclic stress, chemical degradation, over-pressurization, or installation damage.
