Key Features & Benefits

Our 3/4" hydraulic hose is designed with a focus on longevity, safety, and performance. Each feature addresses a critical need in high-pressure hydraulic systems.

• Superior Tube & Cover Compatibility: Features a synthetic rubber tube resistant to a wide range of hydraulic oils, fuels, and lubricants, paired with a rugged cover that offers excellent abrasion, weather, and ozone resistance.
• High-Tensile Steel Wire Reinforcement: Multi-spiral high-tensile steel wire braiding provides exceptional strength and impulse fatigue resistance, ensuring the hose can handle sustained high pressure and pressure spikes without failure.
• Precision Dimensional Consistency: The 3 4 hydraulic hose od and inner diameter (ID) are manufactured to tight tolerances, ensuring a perfect fit with standard SAE J517 fittings and preventing leaks in critical connections.
• Flexibility & Bend Radius: Designed to maintain flexibility even in tight spaces, reducing stress on the hose assembly and simplifying routing in complex machinery layouts.
• Clear & Durable Identification: Each hose length features permanent, legible markings indicating size, pressure rating, SAE specification, and manufacturing date for easy traceability and compliance.

Frequently Asked Questions (FAQ)

What does "3/4 hydraulic hose OD" refer to?

The term "3 4 hydraulic hose od" specifies the hose size. "3/4" refers to the nominal Inner Diameter (I.D.) in inches. "OD" stands for Outer Diameter, which is a critical dimension for ensuring the hose fits within your equipment's space constraints and compatible clamps or sleeves.

What is the difference between SAE 100R12 and 100R13 for a 3/4" hose?

Both are 4-spiral wire braid hoses. SAE 100R12 typically has a thicker cover for maximum abrasion resistance. SAE 100R13 often has a slightly thinner, more flexible cover. Our standard 3/4 hydraulic hose od product meets the specifications for both types, offering an optimal balance of durability and flexibility.

Can this hose be used with bio-degradable (HETG, HEES) hydraulic fluids?

Yes. The tube compound of our standard hose is compatible with common bio-hydraulic fluids like vegetable oil (HETG) and synthetic ester (HEES) based fluids. For specific fluid compatibility beyond our standard range, please consult our technical datasheet or contact our support team.

Do you supply pre-made assemblies or bulk hose?

We supply both. You can order this 3/4 inch hydraulic hose in continuous bulk lengths (e.g., 500ft or 1000ft reels) for your own assembly, or we can provide custom, crimped hose assemblies with your choice of fittings, ready for installation.

What is the minimum bend radius for this 3/4" hose?

The minimum bend radius is approximately 10 inches (254 mm). Bending the hose tighter than this can kink the inner tube, damage the reinforcement, and drastically reduce hose life. Always follow recommended routing practices.
