SAE 100 R3 Hydraulic Hose: High-Pressure, High-Temperature Solution for Demanding Applications
In the world of industrial hydraulics, reliability under extreme pressure is non-negotiable. The SAE 100 R3 hydraulic hose stands as a benchmark for high-performance fluid conveyance, engineered to excel in the most punishing environments. This four-spiral wire reinforced hose is specifically designed to handle very high working pressures and elevated temperatures, making it an indispensable component for heavy machinery and critical systems. As a premier supplier on the global stage, we provide SAE 100 R3 hoses that meet rigorous international standards, ensuring your operations run smoothly, safely, and efficiently.
Product Overview
The SAE 100 R3 is a four-spiral wire reinforced hydraulic hose designed for high-pressure hydraulic systems. Constructed with a synthetic rubber inner tube, multiple layers of high-tensile steel wire reinforcement, and a durable, weather-resistant synthetic rubber cover, it is built to withstand the dual challenges of extreme pressure and thermal stress. This hose type conforms to the Society of Automotive Engineers (SAE) standard, guaranteeing consistent performance, dimensional accuracy, and compatibility with standard fittings. It is the go-to choice for applications where standard hoses fall short, providing a robust and long-lasting solution for fluid power transmission.
Key Features of Our SAE 100 R3 Hose
- Exceptional Pressure Rating: Engineered with four layers of spiral steel wire, our hose delivers superior burst pressure resistance, ensuring safe operation in the most demanding high-pressure circuits.
- High-Temperature Resilience: The specialized tube and cover compounds maintain flexibility and integrity across a wide temperature range, from -40°C to +121°C (-40°F to +250°F), preventing degradation under thermal cycling.
- Superior Fluid Compatibility: The synthetic rubber tube is resistant to a broad spectrum of hydraulic oils, lubricants, and other industrial fluids, minimizing the risk of tube swelling or failure.
- Abrasion & Weather-Resistant Cover: The tough outer cover protects the critical wire reinforcement from abrasion, corrosion, ozone, and weathering, significantly extending service life in harsh outdoor or industrial settings.
- SAE J517 Compliance: Manufactured to strict SAE 100R3 specifications, ensuring reliable performance, interchangeability, and global acceptance in B2B and OEM applications.

Frequently Asked Questions (FAQ)
What is the main difference between SAE 100R2 and SAE 100R3 hose?
The key difference is the reinforcement. SAE 100 R2 hoses have two braided wire layers and are for medium to high pressure. The SAE 100 R3 features four spiral wire layers, providing a significantly higher maximum working pressure and greater impulse fatigue resistance, making it suitable for the most demanding high-pressure applications.
Can I use SAE 100R3 hose with water-based fluids (HFC, HFD)?
While the standard tube is optimized for petroleum-based oils, specific tube compounds compatible with water-glycol (HFC) and water-oil emulsions are available. Please consult our technical team with your fluid type to specify the correct hose construction.
How do I determine the correct hose length for my application?
Always measure the required length along the intended routing path, accounting for hose bend radii (never bend tighter than the minimum bend radius specified). Include sufficient length for connection movement, vibration, and thermal expansion. We recommend adding a small safety margin and can provide cutting and assembly services to your exact specifications.
Do you supply pre-made hose assemblies with fittings?
Yes. We offer complete, ready-to-install SAE 100 R3 hose assemblies. You can specify the hose length, I.D., and the type of end fittings (e.g., JIC 37°, SAE flange, NPT), and we will crimp and pressure-test the assembly before shipment, ensuring a leak-free, reliable connection.
What is your lead time and minimum order quantity (MOQ)?
We support flexible MOQs to cater to both large OEMs and smaller distributors. Standard products are typically available for prompt shipment, while large custom orders have competitive lead times. Contact our sales team for a specific quote based on your volume and requirements.
