The Bomag 05803123 Piston Seal is a genuine OEM component designed for MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. Sourced directly from Bomag, this piston seal is manufactured to the exact material and dimensional standards of the original part, ensuring a correct, leak-free fit within the hydraulic cylinder assembly. If you're servicing one of these machines, part number 05803123 is the authorized replacement that matches the original specification without compromise.
Key Features
- Genuine OEM Seal Material — manufactured to Bomag's original compound and durometer specifications, maintaining the compression and sealing performance required for hydraulic cylinder integrity
- Direct Cylinder Replacement — engineered to seat correctly within the hydraulic cylinder bore on Bomag recycler/stabilizer machines, requiring no modification to surrounding components
- Confirmed Fitment — verified for the Bomag MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers
- Sustained Hydraulic Pressure — a properly functioning piston seal maintains the pressure differential needed for consistent cylinder force; a worn or failed seal causes slippage, loss of force, and erratic machine response
- Fuel and Fluid Compatibility — OEM seal materials are formulated to resist hydraulic fluid degradation, preventing swelling or cracking that aftermarket compounds may be susceptible to over time
A piston seal sits inside a hydraulic cylinder and creates a pressure-tight barrier between the two sides of the piston, allowing hydraulic force to move the cylinder rod in a controlled direction. On recycler/stabilizer machines like the MPH 121 and MPH 122 series, the hydraulic system powers critical working functions, so a healthy piston seal is essential to consistent, controllable operation. When this seal wears out or fails, the cylinder loses the ability to hold pressure effectively, resulting in sluggish response, reduced working force, and potential fluid bypass that can accelerate internal component wear.
