Core Features & Technical Advantages

Robust Multi-Layer Construction for Extended Service Life

At the core of the SAE 100R3 fabric braid hydraulic hose is its purpose-built layered structure. The inner tube is formulated from high-grade oil-resistant synthetic rubber, compatible with a wide range of common industrial fluids, while the dual high-tensile fiber braid reinforcement delivers structural integrity without the added weight and stiffness of steel wire alternatives. The outer cover is engineered to resist abrasion, oil splashes, and weather exposure, protecting the hose from mechanical wear and environmental degradation in both indoor and outdoor installations.

Optimized Flexibility & User-Friendly Handling

Unlike steel-reinforced hydraulic hoses, this low to medium pressure hydraulic hose features a lightweight, highly flexible design that simplifies installation and routing, even in compact or hard-to-reach spaces. Its size-specific minimum bend radius ranges from 70mm for the smallest 3/16" size up to 254mm for the 1-1/4" variant, allowing tight, kink-free routing in complex fluid systems. The low weight per meter (from 0.14kg/m to 0.92kg/m) reduces physical strain during installation and maintenance, cutting down on labor time for your on-site teams.

Reliable Pressure Performance with Industry-Standard Safety

This hose delivers consistent working pressure performance, ranging from 103 bar (1493.5 psi) for 3/16" hose down to 26 bar (377 psi) for 1-1/4" hose. Every batch adheres to a 2:1 proof pressure testing standard and a 4:1 burst pressure safety ratio, a globally recognized benchmark for hydraulic hose safety, ensuring reliable operation even during occasional pressure fluctuations in your fluid systems.

Applications & Industry Use Cases

Broad Fluid Compatibility

The SAE 100R3 hydraulic hose is engineered to convey a wide range of low to medium pressure fluids, including petroleum-based hydraulic fluids, water-based hydraulic fluids, mineral oil, glycol, lubricating oil, emulsions, and hydrocarbons. It is also fully compatible with air, water, and oil transfer applications, making it a versatile all-in-one solution for multi-fluid industrial facilities.

Target Industry Applications

This hose is ideal for a wide range of industrial and commercial use cases, including light hydraulic systems in industrial automation equipment, pneumatic air lines in manufacturing and automotive service facilities, water transfer and cooling systems in agricultural and construction equipment, lubrication oil delivery lines in industrial machinery, and general fluid transfer operations in marine, mining, and material handling facilities.

FAQ

Q1:What fluids and pressure levels is the SAE 100R3 hose designed to handle?

A1:

This hose is ideal for conveying low-pressure petroleum-based and water-based hydraulic fluids, including mineral oil, glycol, lubricating oil, emulsions, and hydrocarbons. It also suits low to medium pressure air, water, and oil applications. Working pressures range from 103 bar (1493 PSI) for 3/16" down to 26 bar (377 PSI) for 1-1/4", with a consistent 4:1 burst pressure safety ratio (e.g., 414 bar burst for 3/16", 103 bar for 1-1/4") and 2:1 test pressure, making it reliable for general low-to-medium duty fluid transfer.

Q2:How does the fiber braid reinforcement contribute to the hose's suitability for low-pressure uses?

A2:

The reinforcement consists of two high-tensile fiber braids (textile-based), paired with an oil-resistant synthetic rubber inner tube and an oil/abrasion/weather-resistant synthetic rubber cover. This fabric construction keeps the hose lightweight, flexible, and cost-effective for low to medium pressure scenarios, while providing adequate strength without the added weight or stiffness of steel wire braids—perfect for applications like air lines, water transfer, or light hydraulic systems.

Q3:What temperature range and environmental resistance does this hose offer?

A3:

The hose operates reliably from -40°C to +100°C, suitable for varied conditions in industrial, automotive, or everyday use. The outer cover is formulated to resist oil, abrasion, and weather exposure, helping maintain performance and longevity when exposed to outdoor elements, chemicals, or moderate mechanical wear in fluid conveyance setups.

Q4:How does weight and bend radius vary across sizes, and what does that mean for practical use?

A4:

Weight per meter is low for easier handling: 0.14 kg/m for 3/16", 0.18 kg/m for 1/4", up to 0.92 kg/m for 1-1/4". Minimum bend radius scales accordingly (70 mm for 3/16", 76 mm for 1/4", 102 mm for 5/16"–3/8", up to 254 mm for 1-1/4"), allowing tight routing in smaller sizes for compact installations, while larger sizes provide higher flow with more generous bends to avoid kinking in low-pressure air, water, or oil lines.
