Description
Overview:
The O-Ring 12x2.5 is a genuine Stihl rubber sealing ring used to stop leaks at high-pressure connections on Stihl cleaning equipment. Sized 12 mm x 2.5 mm (approximately 0.47 inches x 0.10 inches), it provides a tight, reliable seal between mating parts such as hoses, lances, pumps, and fittings. Built from durable elastomer rubber in a round cross-section, it suits demanding, wet environments found in pressure washing. It is specified for Stihl RE-series pressure washers including RE140K and RE160K, and is also listed for selected other Stihl machines where this size is required. Using the correct OEM O-ring helps maintain working pressure, reduces water loss, and supports long service life of the equipment.
