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.
The Marsh Brothers Aviation upgrade kit includes a non-metallic piston made from their proprietary polymer AeroTough® GF, and state of the art Thorseals®, replacing the OEM aluminum piston fitted with a nitrile rubber o-ring, back up rings and a PTFE rider ring.
The following kit contains either:
A) 1 x Hydrodyne Hydraulic Accumulator (M1030)
B) 1 x York Hydraulic Accumulator (M1031)
