Description

Overview:
This O-ring N7, 52 x 3.53 mm, is a genuine Stihl part designed for sealing duties in Stihl sprayers. Made from NBR70 (nitrile rubber, 70 Shore A hardness), it provides a reliable, flexible seal that helps maintain system pressure and prevents leaks at specified joints in the liquid circuit. Its size and compound are matched to Stihl requirements for long service life in contact with water-based solutions and common spraying chemicals. Suitable for handheld and backpack sprayers, including models such as SG 21 and SG 51, it is a direct replacement that preserves performance and safety. Genuine Part status ensures correct fit and compatibility with the intended assemblies on your Stihl equipment.

Key Features:
- Genuine Stihl OEM seal for assured compatibility and reliability
- Size: 52 x 3.53 mm for the specified Stihl sprayer applications
- NBR70 nitrile rubber for resilience, flexibility, and stable sealing force
- Good resistance to water-based sprays, oils, and many common agricultural chemicals
- Durable compound with strong wear and abrasion resistance
- Maintains pressure and reduces the risk of leaks during operation
- Consistent fit helps minimise downtime during routine maintenance
- Simple to install and remove with basic hand tools
- Suitable for periodic seal replacement to restore system integrity
- Black, round cross-section O-ring for standard gland grooves
