Hydraulic Hose Sizes, Reinforcement and Operating Requirements
This listing covers steel-wire reinforced hydraulic rubber hose. The listed internal-diameter range is 6–51 mm. Select the exact size and construction according to the fluid, pressure, temperature and installation requirements.
Different hose constructions have different operating limits. Steel-wire reinforcement alone does not establish working pressure or media compatibility. Request the technical sheet for the ordered specification.
Product Specifications
The supplied size and construction determine the ratings. Confirm the following options against a size-specific technical table.
| Product Type | Steel-wire reinforced hydraulic rubber hose |
|---|---|
| Listed Internal-Diameter Range | 6–51 mm; confirm available sizes and tolerances |
| Listed Roll-Length Options | 20, 40, 50 or 100 m; confirm availability by specification |
| Reinforcement Options | Listed range: 1–6 steel-wire layers; confirm braid or spiral construction and applicable model |
| Material | Synthetic rubber; request lining and cover compound details |
| Outer Color | Black |
| Working Pressure | Request the rating for the selected size, construction and temperature |
| Temperature Limits | Request the approved range for the intended fluid |
| Bend Radius | Request the specified minimum bend radius |
| Order Unit | Confirm sample length, cut piece or roll and the corresponding minimum quantity |
How Do You Select the Correct Construction?
Select by documented performance rather than wire-layer count alone. Supply the operating pressure, pressure fluctuations and required routing conditions.
Fluid: Exact hydraulic fluid type and relevant composition.
Pressure: Normal operating pressure and expected transient conditions.
Temperature: Fluid temperature and surrounding environment.
Size: Required internal diameter and permitted pressure drop.
Routing: Bend radius, movement, abrasion and installation clearance.
Connections: Approved fittings and assembly requirements.
A rated hose assembly includes compatible fittings. Hose and fittings must be selected and assembled as a documented combination.
Can Hydraulic Hose Be Used for Gas or Fuel?
Hydraulic service does not establish suitability for gasoline, LPG or CNG. Each medium requires confirmation of materials, pressure, temperature, permeability and assembly requirements.
Gasoline: Identify the fuel specification and relevant blend components.
LPG: Identify composition, liquid or vapor phase and operating conditions.
CNG: Identify pressure circuit, permeability requirements and applicable product documentation.
Other fluids: Request compatibility confirmation for the exact medium.
This general listing does not establish high-pressure CNG cylinder-line suitability. For a separate low-pressure vehicle product, see our 10mm autogas hose listing. Its specifications must not be transferred to this hydraulic hose.
What Should the Size Table Include?
Each hose specification needs its own dimensional and performance data. Request a table that connects the product reference to its ratings.
Internal diameter and tolerance
Outer diameter and tolerance
Reinforcement construction
Rated working pressure
Proof and burst-test requirements
Operating temperature range
Minimum bend radius
Compatible fitting references and assembly instructions
Working pressure, proof pressure and burst pressure are different values. Do not use a test limit as a continuous operating rating.
Which Inspection and Test Records Should Buyers Request?
Routine inspection and design qualification are different activities. Ask which checks apply to each hose, a production batch or the product design.
Dimensions: Diameter, wall construction and specified tolerances.
Pressure testing: Method, medium, pressure, duration and acceptance criteria.
Durability: Impulse or flex testing where applicable to the intended use.
Material compatibility: Exposure conditions and measured results.
Assembly performance: Leakage and retention checks with specified fittings.
Traceability: Hose marking, product reference, batch and inspection date.
Documents should identify the supplied hose construction. Review our certification information and request applicable model-specific records.
How Are Samples, Lengths and Packing Defined?
The quotation must identify the sales unit. A minimum quantity described as one piece does not specify whether it means a sample, a cut length or a complete roll.
Sample length and evaluation charges
Required cut length and tolerance
Roll length and quantity per size
Price per meter, piece or roll
Marking and packaging requirements
Packed dimensions, net weight and gross weight
Custom-size requests require feasibility confirmation. Provide drawings, quantity and required ratings. Confirm tooling or validation requirements where applicable.
Frequently Asked Questions
Does a higher wire-layer count always mean a suitable hose?
No. Suitability depends on the complete specification. Check rated pressure, size, temperature, fluid compatibility, bend radius and fitting requirements.
Are all listed roll lengths available for every size?
Availability must be confirmed by product specification. Request the offered length and packing arrangement for each size in the quotation.
Can I use ordinary hose clamps for a hydraulic assembly?
Use the fitting and retention system specified for the hose. Do not assume a general clamp is suitable. Follow the approved assembly procedure.
What service information should be supplied?
Request installation, inspection and replacement instructions. Include routing limits, permitted movement and damage criteria. Qualified personnel should follow the equipment and hose documentation.
Can I order this with other components?
Combined-order requirements can be reviewed. Specify each item and quantity. Confirm technical compatibility separately from shipment consolidation.
Request a Hydraulic Hose Quotation
Send the fluid and operating conditions for selection. Include pressure, temperature, internal diameter, routing, fittings, required length and quantity.
Confirm the exact construction before payment. Request the technical sheet, assembly requirements, test documents, sales unit, price, warranty and delivery lead time.
