FDA Colored Silicone O Rings Encapsulated , Industrial O Rings High Flexibility
Silicone O Rings also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.

Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.
Temperature Range:
Standard Compound: -60° to +220°C
Hardness (Shore A): 35 to 85
Features: Phenyl (PVMQ) based silicones can perform to -40°C. New polymers can take short term to 220°C.
Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK) or concentrated acids.
