It accepts tubing with a 12mm outside diameter and is rated to 145 psi, making it suitable for compressed air lines and low-pressure fluid distribution. The body is constructed from polybutylene, which offers good chemical resistance and a lightweight profile. This fitting installs without tools by inserting tubing directly into each port until it locks. It is used by HVAC technicians, pneumatic system installers, and industrial maintenance trades wherever a Y-branch connection is needed in a tubing run.\u003c\/p\u003e\n\u003cp\u003eThis union Y fitting is intended for use in pneumatic control systems, automation equipment, and air distribution networks where a single tubing line must branch into two downstream circuits. The push-to-connect design speeds up installation and allows tube removal by depressing the release collar. Typical installations include instrument air lines, pneumatic actuator feeds, and light-duty process tubing applications. It is sold in single-piece quantities, making it practical for both service calls and new installations requiring only a single branch point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12mm outside diameter tube connection on all three ports\u003c\/li\u003e\n  \u003cli\u003e145 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003ePolybutylene body construction for chemical resistance and light weight\u003c\/li\u003e\n  \u003cli\u003eTool-free push-to-connect installation with integrated release collar\u003c\/li\u003e\n  \u003cli\u003eUnion Y configuration creates a single inlet to dual outlet branch in a tubing run\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation push-to-connect union Y fitting for pneumatic and fluid tubing systems using 12mm outside diameter tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed or qualified pneumatic systems technician should install this fitting in accordance with applicable system design codes and pressure ratings. Before servicing any tubing connection, depressurize and lock out the air supply to prevent sudden line release. Ensure cut tubing ends are clean, square, and free of burrs before insertion to achieve a proper seal. Do not exceed the rated working pressure of 145 psi during system operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 12mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polybutylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SMC PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KCU12-00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52007899988274,"sku":"KCU12-00","price":26.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16e4b8183d64177d85cd109e798ba0a5.jpg?v=1790002064","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kcu12-00-union-y-push-to-connect-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
