SMC KQ2ZD10-04NS Push to Connect Fittings (KQ2ZD1004NS)<\/h1>\n
<\/div>\n

1. Product Overview<\/h2>\n
<\/div>\n
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.<\/div>\n

Function<\/th>\nDetailed Description<\/th>\n<\/tr>\n<\/thead>\n
Tool-Free 10 mm Tube Connection<\/td>\nPush-in insertion of 10 mm OD tubing; internal collet and chuck lock the tube securely without tools, reducing assembly time and labor costs<\/td>\n<\/tr>\n
High-Flow Straight Pipeline Connection<\/td>\nStraight-through bore design minimizes pressure drop, maximizing airflow for large pneumatic actuators and high-demand pneumatic circuits<\/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 sealant application errors<\/td>\n<\/tr>\n
Low-Effort Tube Disconnection<\/td>\nDual-action release collar disengages the collet and chuck simultaneously, enabling easy tubing removal without damaging the tube or fitting<\/td>\n<\/tr>\n
Vacuum & Positive Pressure Compatibility<\/td>\nOperates reliably from full vacuum (-100 kPa) to positive pressure (1.0 MPa), suitable for both suction and pressure-driven pneumatic applications<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

3. Technical Features<\/h2>\n
<\/div>\n
    \n
  1. Dual-Action Release Mechanism<\/strong>: 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.<\/li>\n
  2. Corrosion-Resistant Build<\/strong>: Brass body with electroless nickel plating resists rust and chemical corrosion; SUS304 stainless steel internal components enhance wear resistance and longevity.<\/li>\n
  3. Integrated Sealing System<\/strong>: Pre-applied PTFE thread sealant and NBR O-rings ensure leak-free performance, eliminating the need for additional sealants or gaskets and simplifying installation.<\/li>\n
  4. Broad Tubing Compatibility<\/strong>: Works with 10 mm OD tubing made of polyurethane (PU), nylon, polyethylene (PE), FEP, and PFA, offering flexibility for various application requirements.<\/li>\n
  5. Wide Operating Range<\/strong>: Functions at temperatures from -5\u00b0C to 60\u00b0C and pressures from -100 kPa to 1.0 MPa, adapting to diverse industrial environments and vacuum\/positive pressure systems.<\/li>\n
  6. High Structural Integrity<\/strong>: 3.0 MPa proof pressure rating (at 23\u00b0C) ensures safety during pressure testing and unexpected pressure spikes in pneumatic circuits.<\/li>\n
  7. RoHS Compliance<\/strong>: Meets international environmental standards, free of restricted hazardous substances, suitable for eco-conscious manufacturing facilities.<\/li>\n<\/ol>\n
