Application-Based Selection Guide

Last Updated:
September 2026


1️⃣ Purpose of This Article

This article helps users select the correct hydraulic hose and fitting based on application, not just size or appearance.

Different applications require different:

  • Pressure ratings

  • Hose constructions

  • Fitting standards

  • Sealing methods

  • Safety considerations

Correct application-based selection:

  • Improves system reliability

  • Extends hose life

  • Reduces leakage and failure

  • Improves customer satisfaction


2️⃣ Core Selection Principle (Golden Rule)

Always select hose and fittings based on application requirements, not availability or appearance.

Never downgrade specifications to “make it fit”.


3️⃣ Automotive Applications

Typical Systems

  • Power steering

  • Engine oil lines

  • Fuel lines

  • Transmission cooling

  • Brake hydraulic systems

Recommended Hose Types

  • SAE 100R1 / 1SN

  • Low to medium pressure hoses

Recommended Fittings

  • Metric fittings

  • Banjo fittings (common in Japanese vehicles)

  • ORFS (for leak-sensitive systems)

Key Considerations

  • Temperature resistance

  • Oil / fuel compatibility

  • Limited installation space

⚠️ Brake systems require special brake-rated components only.


4️⃣ Construction & Heavy Machinery

Typical Systems

  • Excavators

  • Loaders

  • Cranes

  • Bulldozers

Recommended Hose Types

  • SAE 100R2 / 2SN

  • 4SP / 4SH (high pressure)

Recommended Fittings

  • JIC 37°

  • ORFS

  • SAE Flange (3000 / 6000 PSI)

Key Considerations

  • High pressure & shock loads

  • Abrasion resistance

  • Strong hose routing protection


5️⃣ Industrial & Factory Machinery

Typical Systems

  • Hydraulic presses

  • Injection molding machines

  • CNC equipment

  • Production lines

Recommended Hose Types

  • 2SN

  • Compact high-pressure hoses

Recommended Fittings

  • ORFS (preferred for leak control)

  • Metric flat seal

  • SAE Flange

Key Considerations

  • Continuous operation

  • Clean environment requirements

  • Easy maintenance and replacement


6️⃣ Agricultural Machinery

Typical Systems

  • Tractors

  • Harvesters

  • Sprayers

Recommended Hose Types

  • 1SN / 2SN

  • Medium pressure hoses

Recommended Fittings

  • BSP / BSPT

  • Metric fittings

Key Considerations

  • Dust and contamination

  • Seasonal maintenance

  • Cost vs durability balance


7️⃣ Marine & Mobile Equipment

Typical Systems

  • Hydraulic steering

  • Winches

  • Lifting systems

Recommended Hose Types

  • Corrosion-resistant hoses

  • High-pressure hoses

Recommended Fittings

  • Stainless steel fittings

  • ORFS or JIC

Key Considerations

  • Corrosion resistance

  • Vibration

  • Safety-critical operation


8️⃣ High-Temperature & Special Media Applications

Typical Media

  • Hot hydraulic oil

  • Bio-oil

  • Chemical fluids

Selection Notes

  • Verify hose inner tube compatibility

  • Check maximum temperature rating

  • Use fittings with appropriate seals

Never assume standard rubber hoses are compatible.

Application အလိုက် Hydraulic Hose & Fitting ရွေးချယ်နည်း

 


၁️⃣ ဤ Article ၏ ရည်ရွယ်ချက်

ဤ Article သည်
Hydraulic Hose နှင့် Fitting များကို
အသုံးပြုမည့် Application အလိုက် မှန်ကန်စွာ ရွေးချယ်နိုင်ရန်
လမ်းညွှန်ပေးရန် ရည်ရွယ်ပါသည်။

Size တူရုံနဲ့ မလုံလောက်ပါ။
Application မကိုက်ရင် ပျက်တတ်ပါသည်။


၂️⃣ အခြေခံစည်းမျဉ်း

Application ကို အရင်စဉ်းစားပါ၊ ပစ္စည်းကို နောက်မှရွေးပါ


၃️⃣ ယာဉ် (Automotive) အသုံးပြုမှု

အသုံးများသောနေရာများ

  • Power steering

  • Engine oil line

  • Fuel line

သင့်လျော်သော Hose

  • 1SN / SAE 100R1

သင့်လျော်သော Fitting

  • Metric

  • Banjo

  • ORFS

⚠️ Brake system များအတွက် သီးသန့်ပစ္စည်းသာ အသုံးပြုရပါမည်။


၄️⃣ ဆောက်လုပ်ရေးနှင့် Heavy Machinery

အသုံးများ

  • Excavator

  • Crane

  • Loader

Hose

  • 2SN / 4SP / 4SH

Fitting

  • JIC

  • SAE Flange

ဖိအားမြင့်၊ Shock များသောကြောင့်
အရမ်းအရေးကြီးပါသည်။


၅️⃣ စက်ရုံနှင့် Industrial Machinery

Hose

  • 2SN
