SMC KXL12-04S Male Elbow Rotary One-touch Fitting (KXL1204S)<\/h1>\n
<\/div>\n

1. Product Overview<\/h2>\n
<\/div>\n
The SMC KXL12-04S is a high-performance 90\u00b0 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\u00b0 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.<\/div>\n

2. Main Functions<\/h2>\n
<\/div>\n
\n
\n\n\n\n\n\n\n\n\n\n\n
Function<\/th>\nDetailed Description<\/th>\n<\/tr>\n<\/thead>\n
360\u00b0 Rotary Connection<\/td>\nThe 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.<\/td>\n<\/tr>\n
Tool-Free Tube Installation<\/td>\nPush-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.<\/td>\n<\/tr>\n
90\u00b0 Elbow Pipeline Routing<\/td>\nRight-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.<\/td>\n<\/tr>\n
Leak-Proof Threaded Interface<\/td>\nR1\/2 male thread with pre-applied PTFE sealant ensures airtight connection to valves, regulators, and manifolds, eliminating leak risks from improper sealant application.<\/td>\n<\/tr>\n
Vacuum & Positive Pressure Compatibility<\/td>\nOperates reliably across -100 kPa (full vacuum) to 1.0 MPa, suitable for both vacuum suction systems and high-flow positive pressure pneumatic actuation tasks.<\/td>\n<\/tr>\n
Quick Tubing Disconnection<\/td>\nPush-to-release collar disengages the collet rapidly, allowing tool-free tubing removal for maintenance, replacement, or system reconfiguration without damaging the tube or fitting.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

3. Technical Features<\/h2>\n
<\/div>\n
    \n
  1. 360\u00b0 Rotary Joint Design<\/strong>: Precision ball bearing structure enables smooth, low-friction rotation, with a rotational torque of \u22640.5 N\u00b7m, ensuring flexible pipeline movement without airflow interruption.<\/li>\n
  2. Robust One-Touch Locking Mechanism<\/strong>: Dual collet and chuck system delivers high clamping force, preventing tubing disconnection even under extreme vibration or pressure fluctuations in industrial environments.<\/li>\n
  3. Corrosion-Resistant Construction<\/strong>: Brass body with electroless nickel plating resists rust, humidity, and chemical contaminants; SUS304 stainless steel internal components enhance wear resistance and service life.<\/li>\n
  4. Pre-Applied Thread Sealant<\/strong>: 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.<\/li>\n
  5. Broad Tubing Compatibility<\/strong>: Compatible with 12 mm OD tubing made of polyurethane (PU), nylon, and polyethylene (PE), providing flexibility for diverse application requirements.<\/li>\n
  6. Wide Operating Conditions<\/strong>: Functions stably at temperatures ranging from -5\u00b0C to 60\u00b0C, adapting to typical industrial working environments with non-condensing relative humidity.<\/li>\n
  7. High Safety & Durability<\/strong>: Boasts a 3.0 MPa proof pressure rating (at 23\u00b0C), ensuring structural integrity during pressure testing; RoHS compliant, free of restricted hazardous substances.<\/li>\n<\/ol>\n
