The Multiquip EM70904 Piston Cup Kit BV-80 is a genuine OEM Piston Cup Kit designed for the BV-80. As a factory-original component, it is manufactured to the exact material and dimensional standards required for proper fit and sealing performance in your BV-80 equipment. Sourced directly through Multiquip's authorized parts network, EM70904 ensures you are installing the correct kit the first time — no guesswork on compatibility.
Key Features
- OEM-Grade Cup Material — Manufactured from the same compound spec as the original, delivering consistent compression and sealing integrity across the full stroke of the piston.
- Direct-Fit Kit for BV-80 — Every cup in this kit is sized and profiled to seat correctly within the BV-80 cylinder bore, allowing straightforward installation without modification.
- Confirmed BV-80 Fitment — Verified for compatibility with BV-80 equipment, so you can order with confidence and get the machine back in service.
- Restores Full Pumping Pressure — Worn or cracked piston cups cause pressure loss and inconsistent output; replacing them with this part restores the pump's designed displacement and delivery performance.
- Fuel and Fluid Compatibility — Cup materials are formulated to resist degradation from the fluids typical to this pump application, supporting a longer service interval between rebuilds.
Piston cups form the primary sealing element between the piston and the cylinder wall inside a pump or pressure-generating assembly. They create the tight seal necessary for the piston to build and maintain pressure on each stroke — without that seal, the pump loses efficiency, output drops, and the machine cannot perform its intended function. When piston cups crack, swell, or wear flat, the result is bypassing fluid, reduced pressure, and in advanced cases, complete loss of pump function. Replacing the cups as a kit ensures uniform seal condition across all positions, restoring full displacement and consistent output.
