Q1: What tube materials are supported?
A: PU 4×2.5 and nylon (PA) 4×2.5. Verify OD tolerance/hardness and run pull/leak tests.
Q2: Where are the two rubber washers located?
A: One beneath the slotted plug, one beneath the M5 mounting seat—both are face-seal positions.
Q3: Do I need PTFE tape or thread sealant?
A: Normally no—the face-seal is sufficient. If site practice requires it, apply a thin layer and keep sealant out of the flow path.
Q4: Is it reusable?
A: Yes. Inspect rubber washers and threads during maintenance; replace worn parts.
Q5: Is it suitable for high-frequency operation?
A: Yes. The dual rubber washers + plated brass build handles frequent cycling and micro-vibration.
Q6: Can it be used for vacuum or higher pressure?
A: Intended for clean, dry compressed air. For vacuum, higher pressure, or special media, validate material compatibility and proof pressure first.
