Description
Overview:
The Clamping Ring 12 (part no. 9991 003 1120) is a genuine Stihl OEM component designed to secure mating parts on selected Stihl machines, including pressure washers and walk-behind mowers. Made from a robust, moulded black polymer that resists corrosion, it provides a firm, reliable hold under vibration and regular use. Its job is to clamp and retain assemblies so hoses, tubes, housings, or attachment points stay correctly seated during operation. This helps maintain consistent water pressure and smooth mechanical function while reducing unwanted movement and wear. Engineered for direct fit on Stihl equipment, it gives a tidy, factory‐spec finish and straightforward servicing. Ideal for owners and technicians maintaining Stihl RE118 and RE128 pressure washers.
Key Features:

Typical Applications:
Used to secure components such as hose unions, tubes, casings, or accessory interfaces on Stihl pressure washers and lawn mowers. Appropriate for routine servicing, replacing fatigued or cracked rings, and resolving issues caused by vibration or loose fittings. Helps keep assemblies tight, supports consistent water delivery on washers, and maintains correct alignment of parts on compatible mowers.
