Smooth Cover Braided Hose vs Wrapped Cover Braided Hose vs Steel Wire Spiral Hose
The right selang hidrolik tekanan tinggi is not only about pressure. Cover finish, abrasion environment, impulse cycle and routing space decide whether smooth cover braided hose, wrapped cover braided hose or steel wire spiral hose is more suitable.
| Product type | Structure | Best use | Advantages | Selection caution | Internal link |
|---|---|---|---|---|---|
| 光面编织液压胶管 | Oil resistant synthetic rubber tube, 1 or 2 steel wire braid, smooth abrasion/weather resistant cover | OEM equipment, factory MRO, forklifts, tractors, clean routing | Clean appearance, easy wiping, practical for compact routing | Protect cover if the hose rubs against sharp metal or stone | 光面编织液压胶管 |
| 布纹外覆钢丝编织液压胶管 | Oil resistant tube, 1 or 2 steel wire braid, wrapped cover texture | Construction repair, agriculture field service, outdoor maintenance | Stronger field-service look, practical for rough handling | Check bend radius and clamps in moving equipment | 布纹外覆钢丝编织液压胶管 |
| Wrapped Cover Steel Wire Spiral Hose | Oil resistant tube, 4 or more spiral steel wire reinforcement, wrapped cover | Excavators, mining, high impulse circuits, heavy hydraulic cylinders | Higher pressure and impulse resistance for severe-duty machines | Requires matched ferrule, fitting stem and crimping diameter | Steel Wire Spiral Hydraulic Hose |
SAE 100 R1/R2 and 4SP/4SH Detailed Specification Guide
The values below are typical catalog ranges from common EN 853 and EN 856 hydraulic hose families. Final quotation should follow the exact hose marking, product datasheet and customer working condition.
| 标准 | Tube | Reinforcement | Cover | Working pressure examples | Minimum burst pressure | Fluid compatibility |
|---|---|---|---|---|---|---|
| EN 853 1SN / SAE 100 R1 type | Oil resistant synthetic rubber | One braid of high tensile steel wire | Oil, weather and abrasion resistant synthetic rubber | DN5 about 250 bar; DN12 about 160 bar; DN25 about 88 bar; DN50 about 40 bar | Typically 4 times working pressure | Petroleum base hydraulic fluids and lubricating oils; water glycol and water/oil emulsions with temperature limits |

Ferrule, Fitting and Crimping Selection
Ferrule, fitting and crimping control decide whether a hydraulic hose assembly can hold pressure safely. Even the correct hose can leak or pull off if the ferrule series, fitting stem and crimp diameter are not matched.
| Assembly item | What to confirm | Why it matters | Common buyer mistake |
|---|---|---|---|
| Ferrule | Ferrule series for 1SN/2SN/4SP/4SH, skive or no-skive requirement, hose OD range | Controls compression between cover, reinforcement and fitting stem | Using braided hose ferrule on spiral hose or mixing brands without crimp data |
| Fitting | Thread type, sealing face, stem type, angle and material | Prevents leakage at machine connection and hose end | Confusing BSP with NPTF, JIC with metric cone, or ORFS with flat face adaptors |
| Crimping | Crimp diameter, die set, insertion depth, orientation and inspection record | Prevents pull-off, leakage and premature failure | Crimping by visual feel without checking the crimp diameter data |
| Assembly length | Overall length, cut length, fitting angle and routing movement | Prevents twist, stretching and bend-radius failure | Measuring old damaged hose after it has stretched or twisted |
Application Guide by Working Condition
| Working condition | Recommended hose family | Recommended action |
|---|---|---|
| General factory hydraulic power unit | Smooth cover braided hose, SAE 100 R1/R2 type | Confirm cleanliness, routing, fitting standard and repeat spare list |
| Excavator, loader and quarry equipment | Wrapped cover braided hose or steel wire spiral hose | Check abrasion, pressure spikes, boom movement and flange/JIC/DIN fitting type |
| Agriculture and plantation field repair | Wrapped cover braided hose and common ferrules | Stock fast-moving sizes before harvest season and confirm BSP/DIN metric threads |
| Mining and high impulse systems | 4SP/4SH steel wire spiral hose | Use matched spiral hose fittings, ferrules and documented crimp diameter |
| Marine or outdoor corrosion environment | Hydraulic hose with suitable fitting material and protection | Check salt spray, corrosion, cover aging, clamp points and maintenance interval |
FAQ: Hydraulic Hose Technical Selection
What information is needed to quote ukuran selang hidrolik?
Send hose marking, inside diameter or dash size, total length, fitting photos, thread type, working pressure, fluid, temperature, machine model and quantity. If the old hose is broken, send both end fittings and any visible printing on the cover.
When should I choose SAE 100 R2 instead of SAE 100 R1?
Choose R2 or EN 853 2SN when the same size needs higher working pressure, stronger reinforcement and better pressure margin. R1 or 1SN is practical for many general hydraulic return, control and medium pressure applications.
When should I choose 4SP or 4SH spiral hose?
Choose 4SP/4SH when equipment has high pressure, strong impulse cycles, heavy movement or severe-duty working conditions. Examples include excavators, mining machines, large hydraulic cylinders and heavy mobile equipment.
Can any ferrule and fitting be crimped on any hydraulic hose?
No. Ferrule, fitting stem and crimp diameter must be matched to the hose family and hose outside diameter. Mixing unverified components can cause leakage, fitting pull-off and safety risk.

Selang Hidrolik Tekanan Tinggi Buyer Checklist
For Indonesian buyers, selang hidrolik tekanan tinggi should be confirmed with hose marking, ukuran selang hidrolik, working pressure, fitting standard and crimping data before purchase. A selang hidrolik tekanan tinggi used on excavators, loaders, mining machines or hydraulic presses normally needs more pressure margin than a general return line.
| Buying question | What to check | Why it affects selang hidrolik tekanan tinggi selection |
|---|---|---|
| What is the hose size? | Dash size, DN size, I.D. and O.D. | Ukuran selang hidrolik affects flow, pressure rating, ferrule size and crimp diameter. |
| What pressure class is needed? | SAE 100 R1/R2, EN 856 4SP or EN 856 4SH | Selang hidrolik tekanan tinggi must be rated above the real machine working pressure. |
| What fittings are used? | BSP, NPTF, JIC, DIN Metric, ORFS or SAE flange | Wrong fitting standard causes leakage even when the hose is correct. |
| How will it be crimped? | Ferrule series, insertion depth and final crimp diameter | Selang hidrolik tekanan tinggi assemblies need matched ferrule, fitting and crimping control. |

FAQ Selang Hidrolik, Fitting dan Hose Assembly
Cara memilih selang hidrolik yang tepat?
Mulai dari ukuran selang hidrolik, tekanan kerja, jenis fluida, suhu, radius tekuk, cover, fitting dan ferrule. Untuk selang hidrolik tekanan tinggi, pastikan working pressure lebih tinggi dari kondisi mesin dan pilih hose family seperti SAE 100 R1/R2 atau EN 856 4SP/4SH sesuai aplikasi.
Berapa tekanan selang hidrolik yang aman?
Tekanan aman mengikuti working pressure pada datasheet hose. Burst pressure hanya referensi keselamatan, bukan tekanan operasi normal. Banyak hose hidrolik memakai rasio sekitar 4:1 antara burst pressure dan working pressure.
Fitting yang cocok untuk selang hidrolik bagaimana dipilih?
Fitting yang cocok harus mengikuti thread, sealing face, fitting stem, ferrule, crimping diameter dan hose series. BSP, JIC, DIN Metric, ORFS dan SAE flange tidak boleh dipilih hanya dari bentuk luar tanpa pengukuran.
