Product Features & Applications
Silicone O-rings provide reliable sealing solutions with round cross-sections designed to fit precisely in grooves, creating effective barriers against liquids and gases. These seals are available for both static and dynamic applications including reciprocating and rotating systems.
Industry Applications
Food & Beverage, Home Appliance, Electronics, Automotive, Consumer Goods, Medical and Healthcare
Common Applications
- Rice cookers, induction cookers, pressure cookers
- Water heaters, vacuum cleaners, juicers
- Lid gaskets, kettles, thermos bottles and cups
- Irons, microwaves, water dispensers, ovens
- Magnetized cups, coffee pots, medicine boxes
Key Advantages
- Excellent sealing performance with waterproof and leak-proof capabilities
- Completely non-toxic and odorless for food-safe applications
- High temperature resistance without deformation or harmful substance generation
- Superior aging resistance with long-term color stability
- Corona and arc resistance with high/low temperature tolerance
- Machine oil resistance with good tensile strength
Technical Limitations
- Limited mechanical properties - primarily suitable for static sealing applications
- Reduced resistance to alkane and aromatic oils
- Not recommended for environments exceeding 50 pounds working pressure
- Higher manufacturing costs compared to some alternative materials
