Conversions Tech Pneumatic Y-Union Quick Fitting – 3-Way Push-to-Connect for PU/Nylon Tubing (4–16 mm OD)
Type: Hose-to-Hose Y-Connector (3 Ways) | Fluid: Compressed Air / Vacuum | Operating Pressure: 0–10.2 kgf/cm² (0–1.0 MPa) | Vacuum: to −750 mmHg (≈10 Torr) | Temp Range: 0–60 °C
Engineered by Conversions Tech for fast, leak-tight pneumatic manifolding, this Y-shape 3-way quick fitting delivers robust push-to-connect performance in automation, packaging, pick-and-place, and laboratory air systems. The precision collet and dual-seal architecture provide repeatable insertion/removal cycles while maintaining low pressure drop across the junction—even under full vacuum.
Key Technical Features
- Geometry: 120° Y-union for balanced branch flow and compact routing.
- Connection: Tool-free push-to-connect with stainless steel collet teeth and elastomer seal.
- Compatibility: PU (polyurethane) and PA (nylon) tubes.
- Body Material: High-strength engineering plastic for impact and chemical resistance.
- Color Options: Black or Blue for line identification.
- Media: Dry, filtered compressed air or vacuum service.

Frequently Asked Questions (FAQs)
1) What tube materials are supported?
Designed for PU (polyurethane) and PA (nylon) tubing with the listed OD sizes. For PTFE or PVC, contact Conversions Tech for compatibility.
2) How do I achieve a leak-tight connection?
Square-cut the tube, deburr, ensure a clean OD, then fully insert until it bottoms. Pull back lightly to seat the collet. Press the collet to release.
3) Is this fitting rated for full vacuum?
Yes—up to −750 mmHg (~10 Torr) with PU/PA tubing in good condition and proper insertion depth.
4) Can it handle lubricated compressor air?
Yes. The elastomer seal is compatible with typical compressor lubricants. Avoid silicone-swell agents or solvent-laden air.
5) What happens near temperature extremes?
At 0 °C or 60 °C, reduce the working pressure for safety. Always observe tubing manufacturer de-ratings.
6) Will the Y-union balance flow equally?
The symmetric 120° body minimizes ΔP. Actual flow split depends on downstream restrictions and tube lengths.
7) Can I use this with water or chemicals?
Intended for dry, filtered air or vacuum. For liquids or chemicals, choose fluid-rated fittings from Conversions Tech.
8) How many reconnection cycles are typical?
With clean tube ends, hundreds of cycles are achievable. Trim the tube if the OD becomes scored by the collet.
9) Does color affect performance?
No. Black and blue bodies provide identical ratings—use colors for line identification on panels.
10) What size should I choose?
Match the fitting OD to your tube OD (e.g., 8 mm tube → 8 mm fitting). Verify ID/wall for desired flow and bend radius.
11) Any installation clearances to consider?
Allow axial space for full tube insertion and radial clearance to depress the collet for release during maintenance.
