What Is SAE 100 Hydraulic Hose?

SAE 100 hydraulic hose is a classification defined by SAE J517 that specifies hose construction, reinforcement type, and pressure ratings for hydraulic fluid power systems. While SAE is widely used, international projects often require other benchmarks; you can learn more in our comprehensive guide, Hydraulic Hose Standards Explained: SAE vs ISO vs DIN Comparison + Selection Chart. Each type (such as 100R1 or 100R2) represents a specific design optimized for different pressure ranges and applications.

This standard is the global benchmark for hydraulic hose selection. Whether maintaining excavators, designing industrial machinery, or sourcing replacement hoses, understanding SAE 100 ratings ensures safety, efficiency, and compliance. This guide covers all active SAE 100 series types, pressure charts, selection criteria, and direct comparisons between R1, R2, and R16.

Each type (such as 100R1 or 100R2) represents a specific design optimized for different pressure ranges and applications.

What Is Dash Size in Hydraulic Hoses?

Dash size is the standard hydraulic hose sizing system where the number equals the inner diameter in sixteenths of an inch. For example, a -08 dash size indicates 8/16″ = 1/2″ inner diameter. Dash sizes range from -03 (3/16″) to -32 (2″). Dash sizes range from -03 (3/16″) to -32 (2″). These measurements, along with pressure ratings and standards, are permanently printed on the side of the hose. If you want to identify these markings on your current equipment, check out our guide on how to read a hydraulic hose layline.

Common Dash Size Reference:

-04 = 1/4″ ID
-06 = 3/8″ ID
-08 = 1/2″ ID
-10 = 5/8″ ID
-12 = 3/4″ ID
-16 = 1″ ID
-20 = 1-1/4″ ID
-24 = 1-1/2″ ID
-32 = 2″ ID

What Is Working Pressure vs Burst Pressure in Hydraulic Hoses?

Working pressure is the maximum continuous pressure at which a hose can safely operate. Burst pressure is the pressure at which the hose will fail catastrophically. SAE J517 requires a minimum 4:1 design factor, meaning burst pressure equals four times working pressure.

For an SAE 100R2 -08 hose with 4,000 psi working pressure, minimum burst pressure is 16,000 psi. Never exceed working pressure. Pressure spikes should remain within 125% of working pressure for intermittent operation.

How to Select the Right SAE 100 Series Hose (5-Step Process)

Step 1: Determine Maximum System Operating Pressure

Measure maximum continuous system pressure including spikes. Select hose with working pressure at least 25% above this value. Operating a hose at 20% above its working pressure reduces service life by approximately 50%.

Step 2: Define Temperature Range

Identify ambient and fluid temperatures. Standard rubber hoses (R1-R6, R12-R17) operate from -40°F to +212°F. For 212°F to 250°F, select R12, R13, or R15. For up to 400°F, select R14 PTFE.

Step 3: Measure Available Bend Radius

If required bend radius is less than hose minimum rating, select compact types (R16, R17, R19). Exceeding minimum bend radius by 50% reduces service life by approximately 75%.

Step 4: Verify Fluid Compatibility

Petroleum fluids work with all rubber SAE types. Synthetic or water-based fluids may require R7, R8, or R18. Aggressive chemicals require R14 PTFE.

Step 5: Select Dash Size Based on Flow

Dash size equals inner diameter in sixteenths of an inch. Use manufacturer flow charts to verify velocity does not exceed 20 ft/second in pressure lines or 10 ft/second in return lines.

Typical Applications by Industry

Construction	Excavators, loaders, backhoes	100R2, 100R12, 100R16
Agriculture	Tractors, combines, sprayers	100R1, 100R7, 100R17

Material Handling	Forklifts, lifts, conveyors	100R1, 100R7, 100R16
Industrial Machinery	Presses, injection molding	100R2, 100R12

When to Replace Hydraulic Hose

Based on field testing across construction and industrial sites, replace hoses immediately when any condition appears:

Cover Cracking or Blistering: Surface cracks expose reinforcement.
Leakage at Fittings or Cover: Indicates inner tube failure.
Kinking or Permanent Deformation: Compromised reinforcement.
Cover Abrasion to Reinforcement: Visible wire or textile fibers.
Pressure Drop or Sluggish Operation: Possible internal tube delamination.

For critical applications, establish scheduled replacement intervals at 1-2 years for high-impulse equipment.

How to Choose a Hydraulic Hose Supplier

For procurement and engineering teams, evaluate suppliers on these five criteria:

Criterion	What to Look For
Certification	ISO 9001, MSHA approval for mining applications
Testing	100% proof pressure testing, burst test documentation, impulse cycle data
Lead Time	Stock availability on common dash sizes (-04 to -24), custom assembly lead time
Custom Capability	Custom lengths, crimped fittings, protective sleeving, branded hoses
Global Experience	Project references in construction, mining, agriculture, oil and gas

Real Field Test Data: In field testing on excavator hydraulic systems operating at 2,500–3,500 psi, HENGHUA SAE 100R2 hoses exceeded 200,000 impulse cycles, compared to the SAE J517 minimum requirement of 150,000 cycles. This 33% margin translates to extended service life in high-impulse applications.

Frequently Asked Questions (FAQ)

What is the difference between SAE 100R1 and SAE 100R2?

SAE 100R1 uses single steel wire braid reinforcement for medium pressure (575-3,250 psi). SAE 100R2 uses double steel wire braid for high pressure (1,150-6,000 psi). For -08 size, R2 provides 60% higher working pressure than R1.

What is the difference between SAE 100R2 and SAE 100R16?

Both provide equivalent working pressure ratings. SAE 100R16 achieves this in a smaller outer diameter with 40-50% tighter bend radius than R2. R16 is designed for compact equipment where installation space is limited.

What is the difference between SAE and EN hydraulic hose?

SAE J517 is the North American standard. EN 853, 856, 857 are European standards. Many hoses meet both (e.g., SAE 100R2 meets EN 853 2SN). SAE uses 4:1 design factor; EN uses 4:1 for most types. Check manufacturer certifications for dual compliance.

How long does a hydraulic hose last?

Service life varies by application. Light-duty agricultural: 3-5 years. Standard construction equipment: 1-2 years. High-impulse mining: 6-12 months. Replace immediately at signs of wear. Establish scheduled replacement based on operating hours.

What is SAE 100R2AT?

The “AT” suffix indicates “thin cover” construction. SAE 100R1AT and 100R2AT replaced discontinued A (non-removable cover) and B (removable cover) types. AT types use standardized Type S working pressures from the 2009 SAE J517 revision.

Which SAE 100 series is best for high temperature?

SAE 100R14 PTFE with stainless steel braid offers -65°F to +400°F range. For rubber hose, SAE 100R12 through R15 provide ratings to 250°F.
