Avoid a wrong match
- Standard PTL and stainless PTL-MS are separate ranges.
- OD8/10/12 and NPT/G options are not listed.
- Cap torque is not installation torque.
- Verify actual A/B direction and cap clearance.

Helpful for Model Matching:
| Family boundary | PTL-M compact mini push-lock controller, distinct from standard PTL and stainless PTL-MS. Trailing -M identifies mini form; URL timestamps are not model codes. |
| Published interface matrix | Only 4M5,401,6M5,601: OD4/6mm with M5×0.8 or blank-thread-type PT1/8 (01). A/B and optional D give 16 published combinations. |
| Flow direction and colour | A meter-out: controlled thread to tube, free tube to thread. B meter-in: controlled tube to thread, free thread to tube. Verify A/B marking and actual circuit. Blank grey body/release button; D black. |
| Pressure, temperature and tube | Operating 0–1MPa; proof 1.5MPa separately. Negative pressure −750mmHg (10Torr in source). Ambient/fluid −20 to70°C. Soft nylon or polyurethane tubing; confirm medium and tube compatibility. |
| Cap operation and torque | Pull cap to adjust and push to lock. Recommended cap rotation torque M5=0.05N·m; PT1/8=0.08N·m. These are adjusting-cap values, not thread installation torque. |
| Mini dimensions | All four rows: L3.5mm; C Pull29.5/Push28mm. M5 H9mm; PT1/8 H10mm. OD4 K12.5/EA16.5mm; OD6 K13.5/EA19.5mm; EB19mm. Weights 4M5=5g,401=11g,6M5=6.2g,601=12g. A/B same external dimensions. |
| Material boundary | Source describes nickel-plated brass corrosion resistance. Do not describe PTL-M as an all-stainless controller. |
| Mini flow-curve boundary | Chinese printed320 top chart row only: PTL4/6M5-M and PTL4/601-M controlled-flow curves at0.5MPa and corresponding free-flow curves versus inlet pressure. Lower standard-PTL charts excluded. Curves do not establish constant speed, safety isolation or leak-tight shutoff. |

No. The official ordering structure uses trailing -M for mini form. Confirm the complete code and label; PTL601A is standard PTL, while PTL601A-M is mini.
