EN856 4SP hydraulic hose features four layers of spiral steel wire reinforcement for high-pressure hydraulic systems. It is widely used in construction machinery, mining equipment, and other heavy-duty applications requiring strength, durability, and stable fluid delivery.
EN856 4SH hydraulic hose is designed for more demanding working conditions and larger size high-pressure applications. With strong spiral reinforcement and reliable pressure resistance, it is a suitable choice for heavy equipment, industrial machinery, and severe service environments.
SAE 100R12 hydraulic hose is built for high-pressure and impulse-intensive hydraulic systems. Its spiral wire reinforcement provides dependable strength and flexibility, making it suitable for heavy machinery, construction equipment, and industrial hydraulic lines under continuous load.
SAE 100R13 hydraulic hose is intended for extremely high-pressure service and frequent pressure surges. It is commonly used in severe-duty hydraulic circuits where strong reinforcement, long-term durability, and consistent performance are required for demanding equipment operation.
SAE 100R15 hydraulic hose offers a higher pressure rating for the most demanding hydraulic applications. Designed for severe duty service, it is ideal for mining machinery, heavy construction equipment, and other systems that require maximum pressure resistance and reliability.

Spiral hydraulic hose is used in high-pressure hydraulic systems that operate under heavy loads, frequent pressure surges, and severe working conditions. It is commonly applied in mining machinery, construction equipment, industrial hydraulic systems, and other heavy-duty applications where strong reinforcement and reliable pressure performance are required.
Both 4SP and 4SH are spiral wire hydraulic hoses designed for high-pressure service, but 4SH is generally used for more demanding applications and larger size hydraulic lines. Compared with 4SP, 4SH is often selected when the system requires higher performance under tougher operating conditions and heavier-duty equipment use.
SAE 100R12 is commonly used for severe-duty hydraulic systems with high pressure and strong impulse loads. SAE 100R13 is a better choice for extremely high-pressure applications requiring higher durability. SAE 100R15 is typically selected for the most demanding hydraulic circuits where maximum pressure resistance and long-term reliability are critical.
In many mining applications, spiral hose is a better choice because it is built for higher pressure, stronger impulse resistance, and more severe working conditions. Braided hose is suitable for many standard hydraulic systems, but spiral hose is usually preferred for mining machinery and other equipment exposed to heavy shock loads and demanding environments.
Spiral hydraulic hose is commonly used with petroleum-based hydraulic oils and can also be suitable for certain biodegradable hydraulic fluids, lubricating oils, water-oil emulsions, and water-glycol fluids, depending on the hose tube material and operating conditions. Fluid compatibility should always be confirmed based on the specific hose type and application requirements.
Yes. We support OEM services for spiral hydraulic hose, including custom branding, layline printing, and packaging options. This helps distributors, equipment manufacturers, and industrial buyers match their market requirements, improve product presentation, and build a more consistent private label or bulk supply program.
