Yatai SAE100 R1 R2 R3 R4 R5 R6 R7 R8 R9 R12 R13 R15 Hydraulic Pipe Fitting Rubber Hose

Hydraulic rubber hoses are typically specified by their SAE standard (e.g., SAE 100R11), internal diameter (ID), working pressure, burst pressure, and temperature range. They are also characterized by their construction, including the tube material, reinforcement (braided or spiral wire), and outer cover. 

Here's a more detailed look at the specifications:

1. SAE Standard:
SAE 100R11: This standard specifies a high-pressure hose with a single-wire braid reinforcement, suitable for medium-pressure applications. 

SAE 100R12: This standard specifies a high-pressure hose with a double-wire braid reinforcement, designed for higher-pressure applications. 

SAE 100R13: This standard specifies a high-pressure hose with four high-tensile steel wire spirals. 

Other SAE standards (like R1, R2, etc.) also exist, each with specific reinforcement and pressure ratings. 

2. Internal Diameter (ID):
The ID is the inside diameter of the hose, typically measured in inches or millimeters.
It determines the flow capacity of the hose. 

3. Working Pressure:
The working pressure is the maximum pressure the hose is designed to withstand under normal operating conditions.
It is typically expressed in pounds per square inch (psi) or bar. 

4. Burst Pressure:
The burst pressure is the pressure at which the hose is expected to rupture or fail.
It is usually several times higher than the working pressure. 

5. Temperature Range:
Hydraulic hoses are designed to operate within a specific temperature range, both for the fluid being conveyed and the ambient temperature. 
This range is typically expressed in degrees Celsius or Fahrenheit. 

6. Construction:
Tube: The inner tube is made of a synthetic rubber compound that is oil-resistant. 
Reinforcement: The reinforcement layers, usually braided or spiral steel wire, provide strength and support to the hose. 
Cover: The outer cover protects the hose from abrasion, UV exposure, and other environmental factors. 

7. Other Considerations:
Fluid Compatibility: Hydraulic hoses are designed to be compatible with specific types of hydraulic fluids (e.g., mineral oils, water, glycol). 
End Fittings: The type of end fittings used with the hose (e.g., NPT, male/female) will depend on the application. 
Hose Length: The length of the hose is also a key specification, determined by the application. 
Standards: Besides SAE, other standards like DIN EN857 and ISO 18752 also exist for hydraulic hoses. 

Q1. How can we guarantee quality?
A1.Always a pre-production sample before mass production.
Always final Inspection before shipment.

Q2. What is your sample policy?
A2.We can supply the sample if we have ready parts in stock, but the customers must pay for the sample and the courier costs.
