York Hydraulic Accumulator

The Marsh Brothers Aerostar Accumulator upgrade kit offers Aerostar owners the option to upgrade the hydraulic accumulator with a fully non-metallic piston and improved dynamic seals.

The non-metallic AeroTough GF® piston eliminates any chance of scratching the cylinder bore during normal operation. The Thorseal material will remain stable over a wide range of operating temperatures and will not swell, shrink or bind.

This kit will also reduce part count from 5 parts under the OEM design to 3 parts under the Marsh Brothers Aviation design, thereby simplifying the assembly.
