Parker’s piston accumulators with crimped end cap design offer pressure rating up to 35O bar. They offer a robust solution without the risk of sudden failure, and provide several other benefits as well.

Parker’s crimped piston accumulators are ideal for use in industrial or mobile applications. They are the strongest and most reliable accumulators in the market. Their outstanding efficiency and robustness makes them suitable for all sorts of applications, from renewable energy to all types of mobile machinery.
See animations below to experience the crimped piston accumulators' benefits in action!
Risk - no sudden failure
The failure mode of piston accumulator seals is over time, allowing for pre-charge adjustment until the equipment’s scheduled maintenance period.  
This allows for longer machine uptime and prevents costly unscheduled maintenance costs. It also ensures greater safety.
Maintenance
The crimped piston accumulators' design allows for long service intervals. They are basically maintenance-free, featuring a sealed-for-life design.

Animation 1 shows the advantage of crimped piston accumulators over membrane accumulators regarding load changes.

Animation 2 highlights the piston accumulators'  supreme non-permeability.
Design
Piston accumulators provide engineers with the option of applying the same capacity accumulator in varying bore sizes.  This can be beneficial when mounting space is at a premium. Also, piston accumulators can be customized to the exact capacity by adjusting the accumulator length, ensuring no gas capacity is unused.
