| Brand | Engmattec |
| Material | Carbon steel, zinc plated |
| Thread | Metric, DIN 2353 heavy (S) series, male |
| Seal | 24° cone seat |
S series carries the high-pressure circuits – same 24° cone as L series but heavier wall and different tube sizes per thread. An L plug will thread into an S port of the same M size; it will also let go at pressure. Check the series, not just the thread.
