SMC KXL12-04S Male Elbow Rotary One-touch Fitting (KXL1204S)
1. Product Overview
The SMC KXL12-04S is a high-performance 90° male elbow rotary one-touch pneumatic fitting from the KXL series, engineered for flexible connection between 12 mm outer diameter (OD) pneumatic tubing and R1/2 male threaded ports. Its core advantage lies in the integrated rotary joint, which allows 360° free rotation of the tubing side relative to the threaded side, eliminating pipeline torsion and fatigue during equipment operation. Designed for dynamic industrial applications such as robotic arm end-effectors, automated conveyor systems, and packaging machinery, this fitting supports a wide pressure range from full vacuum to positive pressure, ensuring reliable leak-free performance. The corrosion-resistant construction and tool-free connection design reduce maintenance downtime, making it a versatile solution for high-vibration and motion-intensive pneumatic circuits.
2. Main Functions
| Function | Detailed Description |
|---|---|
| 360° Rotary Connection | The rotary joint between the threaded end and tube end enables full-circle rotation of the tubing, preventing pipeline kinking, torsion, and wear caused by equipment movement or vibration. |
| Tool-Free Tube Installation | Push-in one-touch mechanism secures 12 mm OD tubing instantly; the internal collet and chuck provide stable clamping force without requiring additional tools, streamlining assembly and reconfiguration. |
| 90° Elbow Pipeline Routing | Right-angle design optimizes space utilization in confined installations, redirecting airflow perpendicular to the threaded port and reducing the need for extra adapters in complex pipeline layouts. |
| Leak-Proof Threaded Interface | R1/2 male thread with pre-applied PTFE sealant ensures airtight connection to valves, regulators, and manifolds, eliminating leak risks from improper sealant application. |
| Vacuum & Positive Pressure Compatibility | Operates reliably across -100 kPa (full vacuum) to 1.0 MPa, suitable for both vacuum suction systems and high-flow positive pressure pneumatic actuation tasks. |
| Quick Tubing Disconnection | Push-to-release collar disengages the collet rapidly, allowing tool-free tubing removal for maintenance, replacement, or system reconfiguration without damaging the tube or fitting. |
3. Technical Features
- 360° Rotary Joint Design: Precision ball bearing structure enables smooth, low-friction rotation, with a rotational torque of ≤0.5 N·m, ensuring flexible pipeline movement without airflow interruption.
- Robust One-Touch Locking Mechanism: Dual collet and chuck system delivers high clamping force, preventing tubing disconnection even under extreme vibration or pressure fluctuations in industrial environments.
- Corrosion-Resistant Construction: Brass body with electroless nickel plating resists rust, humidity, and chemical contaminants; SUS304 stainless steel internal components enhance wear resistance and service life.
- Pre-Applied Thread Sealant: Factory-applied PTFE-based sealant on the R1/2 male thread eliminates the need for Teflon tape, reducing assembly steps and ensuring consistent sealing performance.
- Broad Tubing Compatibility: Compatible with 12 mm OD tubing made of polyurethane (PU), nylon, and polyethylene (PE), providing flexibility for diverse application requirements.
- Wide Operating Conditions: Functions stably at temperatures ranging from -5°C to 60°C, adapting to typical industrial working environments with non-condensing relative humidity.
- High Safety & Durability: Boasts a 3.0 MPa proof pressure rating (at 23°C), ensuring structural integrity during pressure testing; RoHS compliant, free of restricted hazardous substances.
