Description
Overview:
This O-Ring 13.5x1.5 is a genuine Stihl part for maintaining watertight seals in pressure washer systems.

Sized at 13.5 mm diameter x 1.5 mm section, it is engineered for a precise fit in selected Stihl machines such as the RE220K and RE240K. Correct sealing supports efficient performance, stable pressure, and reduced downtime. Supplied as a Genuine Part with Stihl OEM reference 9645 945 1320, it is ideal for routine maintenance and component replacement where seals have flattened, cracked, or perished through use.
