SMC KQ2ZD10-04NS Push to Connect Fittings (KQ2ZD1004NS)
1. Product Overview
The SMC KQ2ZD10-04NS is a premium push-to-connect one-touch fitting from the KQ2 series, featuring a straight-through design for linking 10 mm outer diameter (OD) pneumatic tubing to R1/2 male threaded ports in industrial pneumatic systems. It is engineered with a dual-action release collar for low-force tube removal and a pre-sealed thread for reliable leak prevention, making it suitable for high-flow applications in automotive manufacturing, packaging machinery, and material handling equipment. The compact straight design simplifies pipeline installation in tight spaces, while its corrosion-resistant construction ensures long-term durability and consistent performance in harsh industrial settings with minimal maintenance needs.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Tool-Free 10 mm Tube Connection | Push-in insertion of 10 mm OD tubing; internal collet and chuck lock the tube securely without tools, reducing assembly time and labor costs |
| High-Flow Straight Pipeline Connection | Straight-through bore design minimizes pressure drop, maximizing airflow for large pneumatic actuators and high-demand pneumatic circuits |
| Leak-Proof Threaded Interface | R1/2 male thread with pre-applied PTFE sealant ensures airtight connection to valves, regulators, and manifolds, eliminating sealant application errors |
| Low-Effort Tube Disconnection | Dual-action release collar disengages the collet and chuck simultaneously, enabling easy tubing removal without damaging the tube or fitting |
| Vacuum & Positive Pressure Compatibility | Operates reliably from full vacuum (-100 kPa) to positive pressure (1.0 MPa), suitable for both suction and pressure-driven pneumatic applications |
3. Technical Features
- Dual-Action Release Mechanism: The release collar releases both the collet and chuck at the same time, reducing tube removal force by 20% compared to standard fittings and preventing excessive tube damage during disconnection.
- Corrosion-Resistant Build: Brass body with electroless nickel plating resists rust and chemical corrosion; SUS304 stainless steel internal components enhance wear resistance and longevity.
- Integrated Sealing System: Pre-applied PTFE thread sealant and NBR O-rings ensure leak-free performance, eliminating the need for additional sealants or gaskets and simplifying installation.
- Broad Tubing Compatibility: Works with 10 mm OD tubing made of polyurethane (PU), nylon, polyethylene (PE), FEP, and PFA, offering flexibility for various application requirements.
- Wide Operating Range: Functions at temperatures from -5°C to 60°C and pressures from -100 kPa to 1.0 MPa, adapting to diverse industrial environments and vacuum/positive pressure systems.
- High Structural Integrity: 3.0 MPa proof pressure rating (at 23°C) ensures safety during pressure testing and unexpected pressure spikes in pneumatic circuits.
- RoHS Compliance: Meets international environmental standards, free of restricted hazardous substances, suitable for eco-conscious manufacturing facilities.
