Q1: How is the US different from standard unions?
A: It's a dual push-to-connect, thread-free inline coupler for faster installs, sealed by an O-ring + metal collet for durable, vibration-resistant airtightness.
Q2: Which tube sizes/materials are supported?
A: 4 mm and 6 mm PU or nylon (PA) tubing.
Q3: Recommended installation steps?
A: Cut square, deburr, clean/dry → push fully to the stop → pull-check → pressure-hold/leak-test.
Q4: Is it reusable? Any precautions?
A: Yes. Re-cut scratched or ovalized tube ends before reinsertion to protect sealing surfaces.
Q5: Operating limits?
A: 0–0.9 MPa, 5–60 °C. Avoid aggressive chemicals, long oil immersion, or high temperatures; verify compatibility for vacuum/special media.
Q6: Any flow-direction requirement?
A: No—both ends are equivalent. Route as needed.
Q7: How do I troubleshoot a minor leak?
A: Ensure a clean, square cut and full insertion with a passed pull-check; trim a fresh section if needed and check for debris near the collet/O-ring.
Q8: Is the O-ring replaceable?
A: No. If leakage or grip loss occurs, replace the entire fitting.
