Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this silicone industrial O-ring features an 8.369-inch inside diameter, a 2.878-inch outside diameter, and a 0.139-inch cross-section. The brass core provides structural integrity and chemical resistance, while the silicone outer layer offers excellent flexibility, a wide operating temperature range (-60°C to +200°C), and resistance to many oils, solvents, and weathering. This combination makes it ideal for applications requiring both mechanical strength and resilient sealing, such as in chemical processing equipment, pneumatic and hydraulic systems, and food-grade machinery where hygiene and inertness are paramount.
