A new hydraulic hose assembly shop can lose customers quickly if the hose is correct but the fitting standard is wrong. In the field, many urgent repairs fail because the staff only checks hose size and ignores thread type, sealing face, fitting angle and ferrule compatibility. This guide explains the pipe and fitting standards that a starter hose shop should understand before opening.
Why Thread Identification Matters
Hydraulic leakage is not always caused by a bad hose. Wrong thread identification can damage the port, crush the seal, create unsafe leakage, or make the customer return immediately. For a new shop in Indonesia, thread recognition should be part of every inquiry workflow.
| Standar | Common Seal Type | Typical Use | Shop Stock Priority |
|---|---|---|---|
| BSP | Thread or bonded seal depending on type | Industrial machines, trucks, general hydraulic repair | High |
| JIC | 37 degree metal-to-metal flare | Mobile equipment, excavators, imported machines | High |
| DIN Metric | Metric thread with cone or sealing ring | European equipment, loaders, some excavators | Medium-high |
| ORFS | O-ring face seal | Leak-sensitive and high-vibration hydraulic systems | Sedang |
| SAE Flange | O-ring flange face | Large flow, heavy equipment, mining and construction | Sedang |
Field Identification Process
| Step | What to Check | Tool or Method | Risk if Skipped |
|---|---|---|---|
| 1 | Male or female fitting | Visual inspection | Wrong mating part selected |
| 2 | Thread diameter and pitch | Caliper and thread gauge | Port damage or leakage |
| 3 | Sealing face | Check cone, flare, O-ring or flat face | Seal cannot compress correctly |
| 4 | Angle and orientation | Compare old hose sample | Hose twists during installation |
| 5 | Ferrule series | Match hose family and fitting tail | Pull-off or crimp failure |
Starter Fitting Matrix for a New Shop
Do not buy every standard in full depth at the beginning. Start with common straight fittings, then add 45-degree, 90-degree, adapters and flange stock after local inquiry data becomes clear.
| Customer Segment | Recommended First Standard | Expansion Standard | Reason |
|---|---|---|---|
| Excavator repair | JIC, DIN Metric, BSP | SAE flange, ORFS | Mobile machines use mixed standards |
| Truck hydraulic repair | BSP, JIC | Metric adapters | Fast-moving general repair demand |
| Factory maintenance | BSP, ORFS | DIN Metric | Leak control and planned replacement |
| Mining and quarry | Flange, JIC, DIN | Heavy-duty adapters | High vibration and pressure spikes |
Common Mistakes New Shops Should Avoid
The most common mistake is using thread size as the only selection rule. Two fittings can have similar thread diameter but different seat angle or seal method. Another mistake is mixing a spiral hose ferrule with a braided hose tail or using a light ferrule on a high-impulse application.

FAQ
Which fitting standard should a new Indonesian hose shop stock first?
Start with BSP, JIC and common DIN Metric sizes. Add ORFS and flange after you confirm local demand from heavy equipment, factory maintenance or project customers.
Can one ferrule fit every hose fitting?
No. Ferrule selection must match hose construction, cover thickness, fitting tail and crimp diameter chart.
