Sealing rings are widely used for waterproof sealing and preservation of daily necessities such as fresh-keeping boxes, rice cookers, water dispensers, lunch boxes, insulated boxes, insulated boxes, water cups, ovens, coffee pots, etc.

The sealing ring has excellent sealing performance, high temperature resistance, and low temperature performance. At the same time, it is not easy to age for a long time, non-toxic and harmless. Has undergone a series of quality certifications such as FDA and SGS. Meanwhile, the company uses food grade silicone raw materials to ensure that the silicone sealing ring will not cause any harm to the human body. In the production process of silicone sealing rings, there are molding and adhesive molding. The molded sealing ring is directly formed without any interface. Generally, this type of sealing ring is used for rice cookers and pressure cookers.

Sealing rings are a type of universal basic auxiliary components used to solve leakage and sealing problems. The material used to make sealing rings must have elasticity, resilience, mechanical strength, expansion strength, elongation, tear resistance, and non corrosion and pollution related properties. Therefore, sealing rings are often referred to as rubber sealing rings.

The working principle of sealing rings varies depending on their appearance and shape. For example, O-ring, V-shaped sealing ring, U-shaped sealing ring, and Y-shaped sealing ring are common types of sealing rings, which have a large market share, different purposes, and different usage methods.

① O-shaped sealing rings are suitable for static sealing and reciprocating sealing, as well as for rotary sealing and low-speed rotary sealing. They are mostly used in hydraulic and pneumatic systems, various mechanical equipment, and components.

② The V-shaped sealing ring is suitable for shaft non pressure sealing and reciprocating motion sealing, and needs to be combined with pressure and support rings with cloth clamping plants.

③ The U-shaped sealing ring is suitable for reciprocating motion and can be divided into two types: cloth type and rubber type.

④ The Y-shaped sealing ring is suitable for hydraulic or pneumatic transmission systems with reciprocating motion.
