The Wacker Neuson Seal is a genuine OEM Seal designed for the APT6S and APT6T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a factory-sourced component, this seal is manufactured to the exact material and dimensional standards required by Wacker Neuson for these pump models. It provides a direct, drop-in replacement for the original part, covering the full range of APT6S and APT6T variants. Whether you're servicing a skid-mounted APT6S or a cold weather-configured APT6T, part number is the correct replacement seal for the job.
Key Features
- OEM Material Integrity — Manufactured to Wacker Neuson's specified compound and compression rating for hydraulic sealing performance in pump applications.
- Direct-Fit Replacement — Engineered to the original profile and dimensions, seating cleanly into the designated housing without rework or shimming.
- Broad APT6 Series Coverage — Compatible with APT6S and APT6T pumps across surge brake, electric brake, skid-mounted, and cold weather variants.
- Leak Prevention — A correctly seated seal maintains internal pressure boundaries within the pump, preventing fluid bypass and protecting downstream components from contamination or pressure loss.
- Verified OEM Sourcing — Supplied as a genuine Wacker Neuson part under part number 5200021710, ensuring you receive the same component installed at the factory.
A seal in a pump assembly forms a pressure-tight barrier between moving or mating components, preventing fluid from escaping the intended flow path and keeping contaminants from entering critical internal areas. In pumps like the APT6S and APT6T, maintaining seal integrity is essential to sustaining consistent output pressure and protecting internal components such as impellers and shaft bearings. When a seal degrades or fails, it can cause visible fluid leaks, a drop in pump performance, or accelerated wear on surrounding parts — making timely replacement with the correct part essential to keeping the pump operating as intended.
