The Wacker Neuson Diaphragm is a genuine OEM component designed for the RCP-20 series rebar cutters, including the RCP-20/230 50 Hz, RCP-20/120, and RCP-20/115 models. Sourced directly from Wacker Neuson, this OEM diaphragm is manufactured to the same standards as the part originally installed in your machine, ensuring consistent function and a correct fit every time. Confirmed compatibility across the RCP-20 lineup means you can order with confidence that is the right part for your cutter.
Key Features
- OEM-Grade Membrane Material — Manufactured to Wacker Neuson's original material specification, delivering the correct flexibility and durability expected of a hydraulic or pneumatic diaphragm in demanding cutting applications.
- Drop-In Replacement — Engineered to the exact dimensions of the original, allowing straightforward installation without modification to seating surfaces or retaining hardware.
- Confirmed RCP-20 Series Fitment — Compatible with the RCP-20/230 50 Hz, RCP-20/120, and RCP-20/115 rebar cutters, covering both 50 Hz and US-voltage variants across the RCP-20 range.
- Maintains Cutting Pressure Integrity — A fully functional diaphragm sustains the pressure differential that drives the cutting mechanism; a worn or cracked diaphragm causes pressure loss and inconsistent or failed cutting cycles.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5000216929, giving you traceability and confidence in the part's origin and quality.
The diaphragm is a flexible membrane that separates two pressure chambers within the tool's actuating system, converting fluid or air pressure into mechanical force to drive the cutting action. When the diaphragm is in good condition, pressure builds and releases cleanly with each cycle, producing a consistent and controlled cut through rebar. As the diaphragm ages, it can crack, stiffen, or develop pinholes, causing pressure to bleed across chambers — resulting in sluggish or incomplete cutting strokes and potential damage to downstream components.
