The S350 hydraulic hose is a premium, high-pressure hose engineered to outperform traditional SAE 100R13 hoses, delivering enhanced flexibility, superior constant pressure capability, and outstanding abrasion resistance. Designed with four or six layers of high-tensile steel wire spiral reinforcement, the S350 combines exceptional strength with a compact and ultra-flexible construction, making it ideal for today’s most demanding hydraulic systems.
A key advantage of the S350 is its constant working pressure of 35MPa (approximately 5075 psi) across all hose sizes. Unlike SAE 100R13 hoses, which can exhibit pressure variation based on diameter, the S350 provides uniform pressure performance—simplifying system design, improving equipment reliability, and enhancing safety in high-load applications. This constant pressure design allows for standardized system components and ensures stable performance under dynamic working conditions.
The S350’s compact spiral structure offers significantly greater flexibility than conventional R13 hoses, enabling tighter bend radii and easier routing through confined or complex layouts. This ultra-flexibility reduces installation time, minimizes hose strain at connection points, and supports longer service life in mobile and industrial equipment.
In harsh and abrasive environments, the S350 truly excels. Its advanced abrasion-resistant synthetic rubber outer cover offers exceptional protection against external wear, mechanical impact, and harsh weather exposure—making it well-suited for applications in construction, mining, forestry, and heavy industrial operations.
Additionally, the hose features an oil- and heat-resistant synthetic rubber inner tube that maintains excellent performance with a wide range of hydraulic fluids, even under elevated temperature conditions.
In summary, the S350 hydraulic hose sets a new benchmark for performance by offering constant high pressure, extreme flexibility, and enhanced durability, far exceeding the capabilities of standard SAE 100R13 hoses and delivering reliable operation in the most punishing environments.
