The internal collet grips the tube OD and the O-ring provides the pressure seal. Releasing the tube requires pressing the release collar inward while pulling the tube. This kit provides Y-shape (3-way branch) and W-shape (4-way manifold) configurations for splitting or distributing air, water, or oil flow in pneumatic and fluid control circuits.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Types:\u003c\/strong\u003e Y-shape (3-port) and W-shape (4-port) push-to-connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tubing:\u003c\/strong\u003e Nylon (PA), Polyurethane (PU), Polyethylene (PE) — rigid OD required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Sizes:\u003c\/strong\u003e 4mm, 6mm, 8mm, 10mm, 12mm OD (select size)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e POM (polyoxymethylene \/ acetal) or PA66 nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material:\u003c\/strong\u003e NBR O-ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Pressure:\u003c\/strong\u003e 0–1.0 MPa (0–145 PSI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range:\u003c\/strong\u003e 0°C to +60°C (standard NBR seal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e Compressed air, water, light oil (non-corrosive fluids)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 20 \/ 100 \/ 500 pieces (select above)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePush-to-Connect vs Threaded Fittings — When to Use Each\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush-to-connect (this product):\u003c\/strong\u003e Fast installation and reconfiguration.

PVC tubing has inconsistent OD tolerances and softens under pressure, causing the collet to lose grip. Use nylon (PA) or polyurethane (PU) tubing for reliable push-to-connect performance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What is the maximum pressure for push-to-connect pneumatic fittings?\"\u003c\/em\u003e — These fittings are rated to 1.0 MPa (145 PSI). For higher pressures, use metal body push-to-connect fittings (e.g., SMC, Festo, Parker Legris) rated to 1.5–2.0 MPa.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"How do I release the tube from a push-to-connect fitting?\"\u003c\/em\u003e — Depressurize the circuit first. Press the release collar (blue or grey ring) firmly inward toward the fitting body while simultaneously pulling the tube straight out. Do not pull at an angle — this jams the collet.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I reuse push-to-connect fittings?\"\u003c\/em\u003e — Yes, multiple times. However, inspect the collet and O-ring after each removal. Replace if the collet teeth are worn or the O-ring is flattened or cracked.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePneumatic automation:\u003c\/strong\u003e Cylinder supply lines, solenoid valve manifolds, vacuum generator circuits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCNC \u0026amp; machining:\u003c\/strong\u003e Coolant mist systems, air blow-off circuits, spindle air purge lines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3D printing \u0026amp; laser cutting:\u003c\/strong\u003e Air assist distribution, cooling circuits, enclosure purge systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLaboratory \u0026amp; medical:\u003c\/strong\u003e Gas distribution panels, instrument air supply, analytical equipment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIrrigation \u0026amp; fluid control:\u003c\/strong\u003e Water distribution manifolds, drip irrigation splitters, dosing system circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCut tubing with a sharp tube cutter or razor blade — a clean, square cut is essential for a leak-free seal.
