Description
Overview:
This O-Ring 25x2.5 is a genuine Stihl OEM seal designed to maintain airtight and fluid-tight joints in power tools and small engines. Made from durable rubber, it provides a reliable barrier to help prevent leaks, pressure loss, and contamination across housings and fittings. Sized 25 x 2.5 mm (approximately 1.0 x 0.1 inches), it is a precise fit for specified Stihl equipment, including the TS50 and 045, and many other classic models. Its compact, circular profile is suitable for static sealing points found throughout cutting tools, chainsaws, and brushcutters. Built for everyday workshop and site use, this O-ring supports consistent performance and reduces the risk of premature wear caused by dried, flattened, or damaged seals.
