Väderstad Seal 161233-M (218920-M) – 25×32×6 mm

OEM Rubber Shaft Seal for Väderstad Seed Drill and Agricultural Machinery

Product Overview

The Väderstad Seal 161233-M (also referenced as 218920-M) is a precision rubber shaft seal (oil seal / dust seal) used in Väderstad agricultural machinery, especially in Tempo precision seed drill systems and related rotating assemblies.

This seal has a size specification of 25 × 32 × 6 mm, designed to protect rotating shafts, bearings, and transmission interfaces from dust, soil, and moisture. It ensures stable operation of mechanical components under harsh agricultural field conditions.

OEM references confirm this part is used in Väderstad systems as a rubber sealing element for agricultural precision equipment, ensuring long-term reliability of moving assemblies.

At Dawopu, we manufacture OEM-quality replacement seals with high sealing performance, wear resistance, and long service life for demanding agricultural environments.
