How to Read Hydraulic Hose SAE Standards [ SAE Standard Hydraulic Hose Guide]

What Is SAE Standard for Hydraulic Hose

SAE (the abbreviation of Society of Automotive Engineers) is the general international standard for hydraulic hoses. 

This SAE Standard provides general, dimensional and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment. 

Our hydraulic hose is qualifed with the SAE certification. And the SAE standard numbers needs to be printed on the surface of the hydraulic hose cover. So now let’s see what these SAE numbers mean for hydraulic hose. 

Let’s start it now!

Hydraulic Hose Structure [Three Layers]

A hydraulic hose is designed with 3 layers, inner tube, reinforcement layer, and outer cover.

Inner Tube: Oil-resistant synthetic rubber inner tube

Reinforcement: Braided or spiral reinforcement, made of steel wire or textile

Outer Cover: Oil and weather-resistant synthetic rubber outer cover. 

SAE 100R1 | 1 Wire Braided Hydraulic Hose

Type A: 

Inner Tube: Oil-resistant synthetic rubber inner tube

Reinforcement: Single layer braided wire reinforcement, is made of one layer of braided steel wire, with high strength.

Outer Cover: Oil and weather-resistant synthetic rubber outer cover. 

Here is a layer of adhesive rubber material between the reinforced steel wire and inner tube & outer cover, to add strength and stability to the whole hydraulic hose. 

Type AT: The structure of this hydraulic hose is the same as the Type A SAE 100R1 hydraulic hose, but without needing to skive the cover when assembling, because of the special size of the outer cover design. 

SAE 100R2AT DIN EN853 2SN Hydraulic Hose

SAE 100R2 | 2 Wire Braided Hydraulic Hose

Type A: 

Inner Tube: Oil resistant synthetic rubber inner tube

Reinforcement: Double layers of braided steel wire reinforcement

Outer Cover:  Oil and weather resistant synthetic rubber outer cover. 

Here is a layer of adhesive rubber material between the reinforced steel wire and inner tube & outer cover, to add strength and stability to the whole hydraulic hose. 

Type AT: The structure of this hydraulic hose is the same as the Type A SAE 100R2 hydraulic hose, but without needing to skive the cover when assembling, because of the special size of the outer cover design. 

The big difference between SAE 100R1 and SAE 100R2 is the layer of the steel wire reinforcement, and SAE 100R2 is structured with 2-wire braided steel wire reinforcement, so it can be much stronger. 

SAE 100R3 Hydraulic Hose

SAE 100R3 | 2TE Textile Reinforced Hydraulic Hose

The structure of the SAE 100R3 hydraulic hose is that: 

Inner Tube: Oil resistant synthetic rubber tube 

Reinforcement: 2 layers of fabric as the reinforcement, the reinforcement is made of cotton fabric textile, and the textile reinforcement is much softer than braided steel wire reinforcement. 

Outer Cover: Oil and weather resistant synthetic rubber outer cover. 

SAE 100R3 can be applied for the Petroleum-based hydraulic oil and water hydraulic hose system with lower pressure.

Outer Cover: Oil and weather resistant synthetic rubber outer layer as the cover. 

Application: SAE 100R4 is mainly used in petroleum-based hydraulic oil and water systems, and can be used in low pressure and suction lines for the hydraulic systems. 

SAE 100R5 | Oil & Mildew Resistant 1-Layer Hydraulic Hose

Inner tube: Oil-resistant synthetic rubber inner tube

Reinforcement:  A fabric textile braided reinforcement layer, add a high-strength braided steel wire layer to combine reinforcement layer

Outer cover: fabric textile braided layer as the outer cover 

All steel wires and cotton textile threads are treated with oil and mildew resistance.

SAE 100R6 | Braided Textile Hydraulic Hose

Structure: SAE 100R6 hydraulic hose is designed with 1-wire reinforcement

Inner tube: Oil-resistant synthetic rubber inner tube

Reinforcement:  A fabric textile braided reinforcement layer
