Manufacturer: Eagle Industry Co., Ltd.
Model: S Series

Features

• Consists of two main parts: O-ring and seal ring. Simple structure minimizing problems and ensuring easy handling
• O-ring serves as the packing; rubber elasticity used to provide a spring force; rubber friction ensures anti-rotation
• Special nitrile rubber characterized by minimal permanent strain used as the standard O-ring material
• Shrink-fit structure employed for the seal ring. Standard materials: highly corrosion resistant stainless steel for the metal parts, and hard metal alloy (characterized by superb corrosion resistance and wear resistance) for the sliding material
• Titanium/Silicon carbide structure for special conditions
• Can be adopted under positive pressure or under back pressure
