Union Straight Type Mini Quick Fitting

  • Brand GENTLE Fittings
Features
  • Ultra-Compact for Tight Routing: ~40% smaller and ~20% slimmer OD for dense layouts in control panels, behind-panel spaces, rail slots, jigs/fixtures, test rigs, and robot wrists.
  • Dual Push-to-Connect, Thread-Free: Both ends are push-in—no threads, no tape. Push fully to lock; ideal for short jumpers, trunk splices, and quick temporary extensions.
  • Airtight & Vibration-Resistant: O-ring + metal collet ensure long-term sealing; for removal, press the release ring evenly.
  • Straight-Through, Low ΔP: Straight bore maintains stable airflow and reduces pressure loss—great for long-run trunk links and distribution.
  • Taiwan-Made, Dual Colors: Black or grey-white (-GW) for clean system matching and circuit ID.
  • Applications: In-cabinet short links, module jumpers, quick line extensions, EOAT/fixture micro lines, and long-run trunk splices.

FAQ

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.
