The Story
Push-to-Connect Pneumatic Union Fittings
Achieve a fast, reliable connection in seconds with our Push-to-Connect Pneumatic Fittings. Designed for high-performance branching and joining of Nylon or Polyurethane (PU) tubing, these one-touch connectors eliminate the need for specialized tools. Simply push the tube into the fitting for an instant, high-pressure seal that stays secure under the toughest conditions.
From tactical vehicle repairs to industrial workshop air lines, these compact fittings are the professional choice for building or maintaining pneumatic and vacuum systems.
Military-Grade Durability & Design
Engineered to withstand heavy vibration and constant pressure cycles, these fittings are built from a robust blend of materials:
-
Stainless-Steel Lock Claws: Provide a permanent, aggressive grip that prevents tube "creep" or blowouts.
-
Zinc-Alloy Collet: Ensures firm tube retention with a smooth, one-touch release for easy maintenance.
-
PA66 & POM Construction: High-strength, wear-resistant polymers that offer excellent dimensional stability.
-
NBR Sealing Rings: Precision-engineered to maintain an airtight vacuum or pressure seal from -20 °C to +70 °C.
Universal Metric Sizing
We stock a comprehensive range of metric sizes to ensure compatibility with standard pneumatic layouts:
-
Tube Sizes: 4mm, 6mm, 8mm, 10mm, and 12mm.
-
Versatile Layouts: Available in Equal and Reducing versions to suit complex air line configurations.
Technical Specifications
| Feature | Rating / Detail |
| Operating Pressure | 0 to 10 bar (0–150 PSI) |
| Maximum Pressure | 15 bar (217 PSI) |
| Vacuum Rating | –1 bar (–100 kPa / –29.5 in Hg) |
| Temperature Range | –20 °C to +70 °C (–4 °F to +150 °F) |

Primary Applications
Reliable performance in the field, the garage, or the factory floor:
-
Vehicle Maintenance: Ideal for trucks, trailers, and military vehicles—specifically air suspension, lockers, and pneumatic braking components.
-
Workshop Installations: Perfect for branching general factory air lines and compressor setups.
-
Automation & Control: Rapid assembly for pneumatic control panels and low-pressure vacuum systems.
