SAE100 R8/EN855 R8 Hydraulic Hose

SAE100 R8 / EN855 R8 Thermoplastic Hydraulic Hose – Flexible R8 Hose

Our SAE100 R8 / EN855 R8 hydraulic hose is a high-quality, thermoplastic flexible hose engineered for mobile and industrial hydraulic systems. It features a PA inner tube, one or two layers of aramid fiber reinforcement, and a black abrasion-resistant polyurethane cover, meeting or exceeding SAE 100R8 specifications. Suitable for transmitting synthetic, petroleum, or water-based hydraulic fluids in demanding environments. 

Non-Conductive hydraulic hose SAE 100R8 is ideal for general purpose medium and high pressure hydraulic applications, the working pressures from 1450 to 5133 psi (depending on size). This hose is commonly used in industrial construction, material handling, and agricultural equipment.

Key Features & Advantages

• Thermoplastic Inner Tube — oil-resistant and compatible with modern hydraulic fluids

• Aramid Fiber Reinforcement — excellent tensile strength and burst resistance

• Abrasion-Resistant PU Cover — protects against weather, wear, and external damage

• Flexible & Lightweight — ideal for mobile equipment and tight routing

• Wide Temperature Range — from –40 °C to +100 °C

• Standard Compliant — meets or exceeds SAE100 R8 / EN855 R8 performance

• Reliable Pressure Performance — supports pressure and burst ratings per spec

Technical Specifications

Typical Applications

• Construction & Earthmoving Machinery — excavators, loaders, bulldozers

• Agricultural Equipment — tractors, harvesters, sprayers

• Mining & Quarrying Machines — hydraulic cranes, drilling rigs

• Forestry & Logging Machinery — feller bunchers, skidders

• Industrial Mobile Equipment — forklifts, aerial platforms

• General Hydraulic Systems — where flexible thermoplastic hose is needed

How They Work

The R8 hydraulic hose comprises three primary layers:

1. Inner Tube: made of oil-resistant thermoplastic (PA), it delivers fluid with minimal degradation.

2. Reinforcement Layer(s): typically one or two braided aramid fiber layers that absorb internal pressure and provide burst strength.

3. Cover: polyurethane outer jacket that provides protection from abrasion, UV, and external damage.

When pressurized, the reinforcement fibers share the stress and maintain hose integrity, while the inner tube ensures fluid compatibility. The flexible design allows for tight routing and movement in equipment.

R8 vs R7 Hydraulic Hose — What’s the Difference?

Although both SAE100 R7 and SAE100 R8 hydraulic hoses are thermoplastic hoses used in hydraulic systems, they differ in construction, performance, and typical applications.

Key Takeaways

• Choose R7 → when cost is a major factor, and you need a lightweight hose for medium pressure, light-duty hydraulic systems.

• Choose R8 → when you need higher pressure resistance, better abrasion protection, and longer service life in demanding environments (construction, agriculture, mining, forestry).

Why Choose Our R8 Hose?

• Strict Quality Control — every hose undergoes burst, pressure, and cold flex testing.

• Custom Options Available — lengths, fitting ends, temperature ranges customizable.

• Material Certification — raw materials certified, full traceability.

• Global Delivery — export packaging and logistic support.

• Technical Support — engineering guidance for hose selection and system design.

FAQ

Q: What does R8 hydraulic hose mean?

A: The “R8” refers to a standard in thermoplastic braided hydraulic hoses defined by SAE100R8 / EN855, indicating design, performance, and construction type.

Q: When should I use R8 vs R7 hose?

A: Use R8 when you need a lighter, more flexible thermoplastic hose with lower weight; use R7 for heavier duty applications with different reinforcement construction.

Q: What is the main difference between R7 and R8 hoses?

A: R7 hoses are designed for medium pressure and general hydraulics, while R8 hoses offer higher pressure tolerance, stronger reinforcement, and better abrasion resistance for heavy-duty applications.

Q: Which is more flexible, R7 or R8 hose?

A: Both are flexible, but R8 hoses are engineered for tighter routing and better bend radius, making them more suitable for mobile equipment.

Q: Which industries prefer R8 hoses?

A: R8 hoses are widely used in construction machinery, agriculture, forestry, mining, and high-pressure mobile hydraulics due to their durability and long service life.

Q: Can I replace R7 with R8 hydraulic hose?

A: Yes, in most cases R8 can replace R7 since it has higher performance. However, R7 is more economical if heavy-duty performance is not required.

Q: What pressure ratings do R8 hoses support?

A: Ratings depend on hose size and construction; typical working pressures might range per dash size (consult size table). Burst pressure is usually several times the working pressure.

Q: Can R8 hoses be used in high temperature environments?

A: Standard R8 hose can handle up to +100 °C, but for higher temps, custom grades or materials may be required.

Q: How do I install hydraulic hose fittings correctly?

A: Select correct fitting type, ensure proper insertion depth, torque per manufacturer specs, avoid twisting or bending beyond minimum bend radius.
