Machinists, automation technicians, and serious DIYers who build pneumatic circuits know that a leaky junction wastes pressure, slows actuators, and creates frustrating troubleshooting sessions. These 304 stainless steel Y-type push-to-connect pneumatic equal connectors are built for exactly that job — delivering a secure, tool-free split in your air line that holds under pressure.\u003c\/p\u003e\n\u003cp\u003eEach piece is a single Y-shaped equal connector machined from 304 stainless steel, with push-fit collet ports on all three legs. Available in five outer-diameter sizes — PY-4mm (≈5\/32\"), PY-6mm (≈1\/4\"), PY-8mm (≈5\/16\"), PY-10mm (≈3\/8\"), and PY-12mm (≈1\/2\") — to match standard pneumatic tubing. Order in quantities of 1, 2, 5, or 10 pieces depending on your project scale.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include splitting air supply lines in automated assembly fixtures, routing compressed air to dual cylinders in DIY pneumatic presses, and building clean branch points in workshop air distribution systems — anywhere a reliable push-fit Y-connector for pneumatic tubing is needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-note\"\u003e\n\u003cspan class=\"hdiy-note-icon\"\u003e⚠️\u003c\/span\u003e \u003cstrong\u003eVerify your tubing OD before ordering.\u003c\/strong\u003e The PY size number refers to the tubing outer diameter (e.g., PY-6mm fits 6mm OD tubing).
