Air Conditioning System Pipe Connection Sealing Ring Description
O-ring: O-ring is one of the most common sealing rings and has an annular cross-section. It can be used to seal gaps at pipe connections to prevent refrigerant or coolant leakage. O-rings are usually made of rubber materials such as nitrile rubber (NBR), fluoroelastomer (FKM) or acrylic rubber (ACM).

U-shaped ring: U-shaped ring is also called lip seal ring, which has a U-shaped cross-section. It is usually used to seal gaps at pipe joints to provide better sealing effect. U-rings are usually made of rubber materials such as nitrile rubber (NBR) or fluoroelastomer (FKM).
Trim Seals: Trim seals are usually made of rubber or plastic material and are used to seal the trim surfaces at pipe connections. They provide a flat sealing surface to ensure sealing performance at the joint.
These sealing rings play an important role at the pipe connections of the air conditioning system, preventing refrigerant or coolant leakage and ensuring the sealing performance of the system.
Regarding the sealing rings for pipe connections in air conditioning systems, the commonly used international standards are O-ring seals and gasket seals. The following are relevant international standards:
O-ring: The O-ring is a circular rubber seal with excellent sealing performance and elasticity. Common international standards include ISO 3601, AS 568 (American standard) and JIS B 2401 (Japanese standard). These standards specify the size, material and performance requirements for O-ring seals to ensure their suitability for pipe connections of different sizes and pressure levels.
Gasket Seal: A gasket seal is a flat sealing material commonly used for flange sealing of pipe connections. Common international gasket standards include ASME B16.21 (American standard), EN 1514 (European standard) and JIS B 2404 (Japanese standard). These standards specify the size, material and performance requirements for gaskets to ensure effective sealing under varying temperature, pressure and media conditions.
