What is SAE100 R1 Hydraulic Hose?

SAE100 R1 (also commonly referred to as SAE100 R1AT) is a widely used high-pressure hydraulic hose standard defined by the Society of Automotive Engineers (SAE). It specifies the construction, performance, and testing requirements for two wire braided reinforced hydraulic hoses used in fluid power systems.

1. Definition of SAE100 R1
SAE100 R1 is a double steel wire braided hydraulic hose designed for high-pressure hydraulic applications.
SAE – Society of Automotive Engineers
100 – Hydraulic hose series
R1 – Two high-tensile steel wire braid reinforcement
A = improved oil resistance
T = higher temperature capability

2. Hose Construction (Inner to Outer Layer)
1) Inner Tube
Material: Oil-resistant synthetic rubber (NBR)
Compatible with: Mineral hydraulic oils, Lubricating oils, Water-glycol fluids, Emulsified oils
2) Reinforcement
Single layer of high-tensile steel wire braid
Provides:
High working pressure
Excellent impulse resistance
Dimensional stability
3) Outer Cover
Material: Abrasion, ozone, and weather-resistant synthetic rubber
Optional properties:
Oil-resistant cover
Flame-resistant cover
Enhanced abrasion resistance

3. Pressure Ratings (Typical)
SAE100 R1 hoses are classified as medium to high pressure hydraulic hoses.
Hose Size Working Pressure (WP) Burst Pressure (BP)
1/4" 22.5 MPa ≥ 90 MPa
3/8" 18 MPa 72 MPa
1/2" 16 MPa ≥ 64 MPa
3/4" 13 MPa ≥ 52 MPa
1" 10.5 MPa 42 MPa
Burst pressure ≥ 3-4 times the working pressure, as required by SAE standards.

4. Temperature Range
Continuous operating temperature: –40°C to +100°C
Intermittent temperature: Up to +125°C

5. Performance Requirements
SAE100 R1AT hoses must meet strict performance tests, including:
Oil resistance test (SAE J517)
Impulse (pulse) test: ≥ 200,000 pressure cycles
Cold flexibility
Adhesion between layers
Ozone and weather resistance

6. Typical Applications
SAE100 R1AT hydraulic hoses are widely used in:
Construction machinery
Agricultural equipment
Mining machinery
Industrial hydraulic systems
Forklifts and material handling equipment
Injection molding machines
Hydraulic presses
