Product Overview

This professional-grade 3/8 hydraulic hose assembly consists of a high-quality SAE 100R2AT or SAE 100R13 hydraulic hose permanently attached to durable, forged steel fittings via a state-of-the-art crimping process. The assembly is available in a variety of standard lengths and can be customized to exact specifications. It is designed to handle a wide range of hydraulic fluids, including petroleum-based oils, synthetic fluids, and water-glycol mixtures, making it a versatile solution for diverse industrial needs. The core of our product is a commitment to exceeding industry standards for pressure ratings, impulse life, and environmental resistance.

Key Features

• Superior Construction: Features a multi-layer design with a synthetic rubber inner tube, high-tensile steel wire reinforcement (one or two braids), and a weather-, abrasion-, and ozone-resistant outer cover.
• Precision-Crimped Fittings: Forged steel fittings are permanently attached using automated crimping machines to ensure a perfect, high-integrity connection that withstands extreme pressure and vibration.
• Excellent Flexibility: Despite its high pressure rating, the hose maintains good flexibility for easier routing and installation in tight spaces, reducing stress on the system.
• Broad Fluid Compatibility: The tube compound is suitable for use with most standard hydraulic fluids, lubricating oils, and water-based fluids.
• Temperature Resilience: Performs reliably across a wide operating temperature range, typically from -40°C to +100°C (-40°F to +212°F).
• Clear Identification: Hose is clearly marked with size, standard, manufacturer, and pressure rating for easy identification and compliance checking.

Technical Specifications

*Pressure rating varies based on hose standard (R2AT vs. R13). Please consult our datasheet for precise ratings.

Application Scenarios

The versatility and robustness of the 3/8 hydraulic hose assembly make it a critical component across numerous sectors. Its primary function is to transmit hydraulic power in high-pressure systems.

• Construction & Earthmoving: Hydraulic circuits on excavators, loaders, bulldozers, and backhoes for boom, arm, and bucket movements.
• Agricultural Machinery: Tractors, combines, and harvesters for steering, lifting, and implement control systems.
• Material Handling: Forklifts, cranes, and conveyor systems for lifting, tilting, and propulsion.
• Industrial Manufacturing: Injection molding machines, presses, stamping equipment, and automation lines.
• Mining & Forestry: Heavy-duty equipment operating in extreme conditions where reliability is paramount.
• Transportation: Truck dump bodies, refuse collection vehicles, and tailgate lifts.

Advantages

Choosing our pre-made 3/8 hydraulic hose assembly over field-assembled alternatives offers significant benefits for B2B buyers and maintenance teams.

• Enhanced Safety & Reliability: Factory-controlled crimping ensures a perfect, consistent connection every time, eliminating the risk of leaks or blowouts due to improper assembly.
• Reduced Downtime: Pre-assembled and ready to install, these hoses drastically cut machine downtime during repairs or maintenance.
• Inventory Simplification: Stocking pre-made assemblies in common configurations reduces the need for separate hoses, fittings, and crimping equipment.
• Optimal Performance: Guaranteed to meet or exceed published pressure and impulse ratings, ensuring the hydraulic system operates at peak efficiency.
• Cost-Effectiveness: While the initial unit cost may be higher, the total cost of ownership is lower due to reduced labor, fewer failures, and less unplanned downtime.

FAQ

Q1: What is the difference between SAE 100R2AT and SAE 100R13 in a 3/8 size?

A: Both are one-wire braid hoses, but SAE 100R2AT typically has a higher maximum working pressure (up to 5,000 PSI for 3/8") compared to SAE 100R13. R2AT also has stricter requirements for impulse life. The correct choice depends on your system's operating pressure.

Q2: Can you make a 3/8 hydraulic hose assembly with different fitting types on each end?

A: Absolutely. This is a common request for adapters or replacement hoses. Simply specify the thread type, sealing style (e.g., JIC, NPT, ORFS), and orientation (straight, 45°, 90°) for each end when ordering.

Q3: How do I determine the correct length for my application?

A: Measure the distance between the two connection ports along the intended routing path. Ensure the hose is long enough to allow for natural movement and flex without being taut, but not so long that it sags or could get snagged. Include allowances for fittings. Our team can assist with complex routing.

Q4: What is the lead time for custom assemblies?

A: For standard configurations, we often ship within 24-48 hours. For large or highly customized orders, lead time typically ranges from 3-7 working days. We provide accurate timelines upon order confirmation.

Q5: Do your hose assemblies come with test certificates?

A: Yes. We can provide batch test certificates upon request, which verify that the hose and the finished assembly meet the declared pressure and performance standards. This is crucial for quality audits and safety documentation.
