The model representation method for hose assemblies usually varies depending on different manufacturers and standards, but generally includes the following parts:

1. Inner diameter specification: usually expressed in inches or millimeters, indicating the size of the inner diameter of the rubber hose. For example, 1/4 inch or 6mm.

2. Pressure level: Refers to the pressure level that the hose can withstand, usually expressed in psi (pounds per square inch) or MPa (megapascals). For example, 3000psi or 20MPa.

3. Level or standard: Some models may include the execution standard or level that the rubber hose meets to ensure compliance with specific technical requirements and quality standards.

4. Processing technology: Some models also include the processing technology of rubber hoses, such as oil resistance, acid and alkali resistance, high temperature and other characteristics.

Combine these parts to form a complete rubber hose assembly model. It is worth noting that different manufacturers and industries may have different representation methods. Therefore, when selecting and ordering hose assemblies, it is necessary to carefully understand and confirm the model representation method to ensure that products that meet the requirements are selected.

If you need to know the specific representation method of a certain model of rubber hose assembly, it is recommended to directly consult a professional manufacturer of rubber hoses at Zaozhuang Jinfulex Rubber Technology Co., Ltd. for accurate information.
