DIN Metric Hydraulic Fitting Selection Guide
DIN metric connections are widely used on European machinery. Correct selection depends on metric thread, tube outside diameter, light or heavy series and the 24 degree sealing geometry.
| Selection point | What to verify | Purpose |
|---|
| Light series | Commonly identified as L series | Confirm tube OD and system pressure |
|---|
| Heavy series | Commonly identified as S series | Used where the specified pressure requires the heavy series |
|---|
| Sealing | 24 degree cone with cutting ring or compatible soft seal design | Do not substitute a visually similar metric connector |
|---|
Technical Questions
Can DIN L and S fittings be mixed?
No. Tube size, cone and thread combinations differ. Match the complete DIN series specification.
Why is tube outside diameter important?
DIN fitting identification uses tube OD together with thread size and series, so thread measurement alone is incomplete.
What should an Indonesian repair team record?
Record machine brand, tube OD, metric thread, L or S series, hose size, pressure and fitting orientation.
Indonesia local service: our Surabaya team supports hose and fitting identification, quotation preparation and assembly planning. Send the medium, size, pressure, temperature, end connections, length and quantity for review.
