Hundreds of pistons for every brand and model; micron-tolerance ground, deep heat-treated, OEM quality. Keeps your breaker hitting like day one.
← Hydraulic Breaker Spare Parts
The piston is the heart of a hydraulic breaker: the moving component that takes hydraulic pressure and gas energy and delivers it as impact to the tool.
HKM pistons are made from high-alloy steel; precision grinding, honing and controlled heat treatment balance surface hardness and toughness.
Features
- High-alloy steel + controlled heat treatment (quench + temper)
- Precision-ground/honed striking and sealing surfaces
- Hardness-toughness balance for long life against breakage and wear
- Full compliance with OEM dimensions and tolerances
Manufacturing & Quality
Every piston is produced with hardness and dimensional control across material certification, heat treatment, grinding/honing and surface finishing.
