GENTLE US Mini Straight Union | Space-Saving Connector for Dense Layou

• Ultra-Compact Body for Dense Layouts: ~40% smaller / ~20% slimmer, ideal inside control panels, behind-panel spaces, tight slots near rails, 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; perfect for short jumpers between modules, in-cabinet links, and quick temporary extensions.
• Airtight, Vibration-Resistant Sealing: O-ring + metal collet deliver long-term airtight reliability; press the collet to release for maintenance.
• Straight-Through Flow Path: Low pressure drop and stable airflow—suitable for trunk-to-branch jumpers and long-run line splices.
• Taiwan-Made, Dual Color Options: Black / grey-white (-GW) for clean system matching and circuit identification.

Q1: What makes US series different from standard unions?
A: US uses a dual push-to-connect, thread-free inline design for faster installation, with O-ring + metal collet sealing for long-term airtightness.

Q2: What tube sizes does the US series support?
A: Available in 4 mm and 6 mm, perfect for compact automation systems.

Q3: Recommended installation steps?
A: Square-cut the tube with a PU tube cutter → push fully to the stop → perform a pull test → leak-test the assembly.

Q4: Is it reusable? Any precautions?
A: Yes—provided the O-ring and metal collet are intact. Re-cut scratched or ovalized tube ends before reinsertion to protect sealing surfaces.

Q5: Operating limits?
A: 0–0.9 MPa, 5–60 °C. Not recommended for aggressive chemicals, long-term oil immersion, or high-temperature service; verify compatibility for vacuum or special media.

Q6: Any flow direction requirement?
A: No—both ends are equivalent. Install in whichever direction suits the routing.

Q7: What should I check if a minor leak occurs?
A: Ensure the tube end is clean and square, the tube is fully inserted, and the connection passes a pull test. If needed, trim a fresh section and reconnect; also verify no debris is caught near the collet/O-ring.
