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

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.
9️⃣ Quick Application Selection Table
| Application | Hose Type | Fitting Type |
|---|---|---|
| Automotive | 1SN | Metric / Banjo |
| Construction | 2SN / 4SP | JIC / Flange |
| Factory | 2SN | ORFS / Flange |
| Agriculture | 1SN / 2SN | BSP / Metric |
| Marine | High-pressure | ORFS / JIC |
🔟 Common Application Selection Mistakes
Using low-pressure hose in high-pressure systems
Ignoring temperature requirements
Choosing fittings based on availability
Using automotive hose in industrial machinery

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
High-pressure compact hose
Fitting
ORFS
Metric flat seal
ဆီယိုမဖြစ်စေရန် ORFS ကို ဦးစားပေးသုံးပါ။
၆️⃣ လယ်ယာစိုက်ပျိုးရေး စက်များ
Hose
1SN / 2SN
Fitting
BSP / Metric
ဖုန်မှုန့်များ၊ Maintenance လွယ်ကူမှုကို စဉ်းစားရပါသည်။
၇️⃣ Marine & Mobile Equipment
လိုအပ်ချက်
Rust မတက်
Vibration ခံနိုင်
Stainless fittings သုံးပါ။
၈️⃣ အပူမြင့် / အထူးအရည်များ
အပူမြင့်ဆီ၊ Chemical များတွင်
Hose material compatibility ကို မဖြစ်မနေ စစ်ပါ။
