The Wacker Neuson Piston Ring 0,01 is a genuine OEM component designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series pumps. As a direct factory part, is manufactured to the exact tolerances required to maintain a proper seal between the piston and cylinder bore. This genuine OEM ring ships as a direct replacement, meaning it installs into your machine the same way the original did — with no guesswork and no adaptation. If your pump is showing signs of reduced compression or increased oil consumption, this is the piston ring to have on hand.
Key Features
- Exact OEM Tolerancing — Manufactured to the precise ring gap and radial wall thickness specs that control compression and oil control in the cylinder bore.
- Drop-In Replacement — Sized and profiled to seat directly into the original ring groove on compatible BPS and A5000 series pistons without machining or modification.
- Broad BPS Series Fitment — Confirmed fit across BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B pumps — covering both standard and wet-applications variants.
- Compression Integrity — A properly seated piston ring maintains cylinder pressure, directly supporting pump output, fuel efficiency, and consistent operating performance.
- Fuel System Protection — Worn or broken piston rings allow oil to enter the combustion chamber, causing excessive smoke, fouled plugs, and accelerated engine wear — replacing this part promptly protects the broader engine assembly.
A piston ring forms a dynamic seal between the piston and the cylinder wall, preventing combustion gases from escaping past the piston and controlling the thin film of oil that lubricates the bore. When a piston ring wears, loses tension, or breaks, compression drops and the engine loses power — you may notice harder starting, rough running, or blue exhaust smoke from oil burning in the combustion chamber. Replacing the ring restores the seal and allows the engine to build full compression again, bringing output and efficiency back to normal operating levels.
