The cutting ring, also known as a sealing ring or O-ring, is a ring-shaped sealing element, generally made of rubber or elastomer, which is used to prevent fluid leaks in hydraulic and pneumatic systems. The cutting ring is designed to fit into a specific groove, called a raceway, a cylindrical or flat surface.
The JIC (Joint Industry Council) is a connection standard commonly used in hydraulic systems, especially in high pressure applications. The JIC utilizes a UNF (Unified National Fine) thread and a 37-degree tapered sealing face to provide a secure, sealed connection.
