Here are some commonly used hydraulic hoses along with their pressure ratings: R1AT/1SN: This is a medium-pressure hydraulic hose with a single steel wire braid reinforcement. It typically has a pressure rating of around 1, 000 to 2, 000 PSI (pounds per square inch). R2AT/2SN: This is a high-pressure hydraulic hose with a double steel wire braid reinforcement. It usually has a pressure rating of approximately 2, 000 to 5, 000 PSI. R12: This is a high-pressure hydraulic hose with a four-wire spiral reinforcement. It is designed for heavy-duty applications and can have a pressure rating of around 4, 000 to 6, 000 PSI. R13: This is an ultra-high-pressure hydraulic hose with a six-wire spiral reinforcement. It is used in extreme conditions and can have a pressure rating of up to 10, 000 PSI or higher. R15: This is a heavy-duty hydraulic hose with a six-wire spiral reinforcement. It is designed for high-pressure applications and can have a pressure rating of around 6, 000 to 8, 000 PSI. 4SH/4SP: These hydraulic hoses have a four-wire spiral reinforcement and are suitable for very high-pressure applications. They can have pressure ratings ranging from approximately 4, 000 to 8, 000 PSI. Thermoplastic hoses: The pressure rating of thermoplastic hydraulic hoses varies depending on the specific type and construction. They can typically handle pressures ranging from 1, 000 to 10, 000 PSI, depending on the design and reinforcement. It's important to note that pressure ratings may vary based on the hose diameter, temperature, and specific manufacturer specifications. It is recommended to consult with hydraulic hose manufacturers or suppliers to determine the precise pressure rating for the desired hose type and size.
