SMC KQ2L12-04NS Male Elbow Fittings (KQ2L1204NS)
1. Product Overview
The SMC KQ2L12-04NS is a high-performance 90° male elbow one-touch pneumatic fitting from the KQ2 series, engineered for secure and tool-free connection between 12 mm outer diameter (OD) pneumatic tubing and R1/2 male threaded ports in industrial automation systems. Designed for high-flow and high-pressure pneumatic applications, it integrates a robust one-touch locking mechanism and pre-sealed thread to ensure leak-free operation, making it ideal for material handling, automotive assembly lines, packaging machinery, and heavy-duty pneumatic circuits. Its compact elbow design optimizes pipeline routing in confined spaces, while the corrosion-resistant construction ensures long service life in harsh industrial environments with minimal maintenance requirements.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Tool-Free Tube Connection | Push-in design enables instant insertion of 12 mm OD tubing; the internal collet and chuck mechanism locks the tube securely without additional tools, reducing assembly time and labor costs. |
| 90° Pipeline Routing | Elbow body redirects airflow at a right angle, eliminating the need for additional adapters and optimizing space utilization in dense automation setups with complex pipeline layouts. |
| Leak-Proof Threaded Connection | R1/2 male thread with pre-applied PTFE sealant ensures airtight integration with valves, regulators, manifolds, and cylinder ports, eliminating the risk of leaks caused by improper sealant application. |
| Quick Disconnection | A simple push on the release collar disengages the collet, allowing fast tubing removal for system maintenance, reconfiguration, or component replacement without damaging the tube or fitting. |
| High-Flow Air Delivery | Large internal bore size matches the 12 mm tubing diameter, minimizing pressure drop and maximizing airflow efficiency for high-power pneumatic actuators and heavy-duty applications. |
3. Technical Features
- Robust One-Touch Locking System: The dual collet and chuck structure provides strong clamping force, preventing tubing disconnection even under high vibration or pressure fluctuations common in industrial environments.
- Corrosion-Resistant Construction: Brass body with electroless nickel plating resists rust, humidity, and chemical contaminants, while stainless steel internal components enhance durability and wear resistance.
- Integrated Sealing Solution: Pre-applied PTFE-based sealant on the R1/2 male thread eliminates the need for Teflon tape, reducing assembly steps and ensuring consistent sealing performance across multiple installations.
- Broad Operating Range: Supports a pressure range of -100 kPa (full vacuum) to 1.5 MPa and a temperature range of -5°C to 60°C, compatible with both vacuum and positive pressure pneumatic systems.
- Multi-Tube Compatibility: Works with various 12 mm OD tubing materials, including polyurethane (PU), nylon, and polyethylene (PE), offering flexibility for different application requirements.
- High Safety Rating: Boasts a 4.5 MPa proof pressure (at 23°C), ensuring structural integrity and preventing catastrophic failure during system pressure testing or unexpected pressure spikes.
- RoHS Compliance: Meets international environmental standards, free of restricted hazardous substances, suitable for eco-friendly manufacturing facilities.
