Unlike push-to-connect fittings with a collet release mechanism, slip-lock fittings use a barbed internal profile that grips the tube OD when inserted and resists pullout under pressure. These PE (polyethylene) body fittings are lightweight, chemically resistant, and suitable for compressed air, water, and light fluid distribution circuits.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type:\u003c\/strong\u003e 3-way equal tee (slip-lock \/ barb-lock)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e PE (polyethylene) — lightweight, chemical resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal:\u003c\/strong\u003e Internal barb profile (no O-ring — relies on interference fit)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Sizes:\u003c\/strong\u003e 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm OD\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e Compressed air, water, light non-corrosive fluids\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 50 or 200 pieces (select above)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSlip-Lock vs Push-to-Connect — Key Differences\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlip-lock (this product):\u003c\/strong\u003e Tube inserts and locks via barb interference. \u003cstrong\u003eNot easily removable\u003c\/strong\u003e — designed for semi-permanent installations.

For higher pressures or temperatures, use nylon (PA) or metal body fittings.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"How do I remove a slip-lock fitting from tubing?\"\u003c\/em\u003e — Slip-lock fittings are not designed for easy removal. To remove: depressurize, cut the tubing close to the fitting, then use pliers to carefully extract the remaining tube stub. The fitting may not be reusable after forced removal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What tubing is compatible with PE slip-lock fittings?\"\u003c\/em\u003e — Nylon (PA), polyurethane (PU), and polyethylene (PE) tubing with consistent OD. Avoid soft PVC — it deforms under the barb and leaks under pressure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Are these fittings suitable for drinking water?\"\u003c\/em\u003e — Standard PE fittings are not certified for potable water.
