|---|---|
| Maximum allowable pressure | 3 MPa |
| Operating temperature range | -5 °C to 60 °C (water 0 °C to 40 °C) |
| M3 thread tightening torque | 0.4–0.5 N·m |
| M5/M6/10‑32UNF thread tightening torque | 1–1.5 N·m |
The fitting is intended for compressed air; other fluids may be used only after confirming with SMC.
The recommended torque for M3 threads is 0.4 to 0.5 N·m.
Clean the hose thoroughly, cut it with a proper hose cutter, and avoid using pliers or scissors that could deform the hose end.
Regular inspections should be carried out according to the manual, checking for damage, leaks, and wear, and replacing parts as needed.
