Parker RK0200K000 Accumulator Seal Kit 2 Inch Bore

Product Description

The PARKER RK0200K000 is a Buna-Nitrile seal kit designed for use with 2-inch bore piston accumulators. The kit provides all sealing components required to service the piston and gas valve ends of a compatible accumulator, making it a practical choice for hydraulic maintenance and repair. Buna-Nitrile construction delivers reliable resistance to petroleum-based hydraulic fluids across a wide range of operating conditions. The inclusion of PTFE glide rings reduces friction on the piston seal, supporting consistent pressure response and extending seal service life. This kit is suited for industrial and mobile hydraulic applications where accumulator performance must be maintained.

This seal kit applies to hydraulic piston accumulator service on industrial machinery, mobile equipment, and fluid power systems. It is used during scheduled maintenance or corrective repair when seal wear, leakage, or system pressure loss indicates seal degradation. The kit covers both the dynamic piston sealing assembly and the static gas valve sealing point, allowing a complete seal replacement in a single service event. Hydraulic technicians and fluid power specialists performing accumulator rebuilds will find all necessary components included.

Key Features

• Sized for 2-inch bore piston accumulators
• Seal material: Buna-Nitrile for compatibility with petroleum-based hydraulic fluids
• Includes V-O-ring piston seal and V-O-ring backups for dynamic piston sealing
• PTFE glide rings reduce piston friction and support seal longevity
• O-ring and O-ring backup provide static sealing at additional interfaces
• Gas valve O-ring included for complete gas-end service

Compatibility

Designed for use with 2-inch bore piston accumulators as specified by PARKER for this kit. Verify accumulator bore size and model against the kit application data before installation.

Installation Notes

Hydraulic technicians should fully depressurize the accumulator and relieve all hydraulic system pressure before disassembly. Discharge the gas precharge per the manufacturer service procedure prior to removing any end caps or fittings. Clean all sealing surfaces and inspect for scoring before installing new seals. Apply a compatible hydraulic fluid or assembly lubricant to seals during installation to prevent damage on initial startup.
