Parker E702970 Bladder Kit 2.5 Gallon Accumulator

Product Description

The PARKER E702970 is a replacement bladder kit designed for use with bladder-style hydraulic accumulators. The bladder is the primary pressure-containing and fluid-separating element inside a bladder accumulator, and replacing it restores the accumulator to proper operating condition. This kit is sized for a 2.5-gallon tank capacity accumulator. Installation is typically performed by hydraulic system technicians or industrial maintenance professionals during scheduled maintenance or after bladder failure is confirmed.

Bladder accumulators are used in hydraulic systems to store energy, dampen pulsation, maintain system pressure, and provide emergency fluid supply. This replacement kit is suited for industrial, mobile, and process hydraulic applications where a 2.5-gallon bladder accumulator is already installed. The kit includes the replacement bladder assembly packaged as a single unit.

Key Features

• Designed as a direct replacement bladder for 2.5-gallon Parker bladder accumulators
• Restores pressure-separation function between gas and hydraulic fluid sides
• Packaged as a single-unit kit for straightforward field replacement
• Compatible with bladder accumulator service in industrial and mobile hydraulic circuits

Compatibility

Designed for use with Parker bladder accumulators of 2.5-gallon tank capacity. No additional specific model compatibility data was provided in the product information.

Installation Notes

Hydraulic system pressure must be fully relieved and the gas pre-charge discharged before opening any accumulator for bladder replacement. This work is typically performed by qualified hydraulic technicians following the accumulator manufacturer's service procedures. Improper bladder installation can result in premature failure or system damage. Always verify the gas pre-charge pressure after reassembly using a calibrated nitrogen charging kit.
