Constructed from polyoxymethylene (POM), a dense acetal resin, this fitting handles pressures up to 300 psi. The push-to-connect mechanism allows tubing to seat and lock in seconds, making it a practical choice for technicians who need a leak-free tee connection during installation or service calls. The tan POM body resists moisture and many common fluids encountered in HVAC, refrigeration, and fluid-handling systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial applications where 5\/16-inch OD tubing is routed in tee configurations. Typical install scenarios include condensate lines, pneumatic control tubing, and low-pressure fluid distribution lines. Plumbers, HVAC technicians, and mechanical contractors install this type of fitting where a compact, tool-free connection is preferred over compression or flare fittings. The single-piece union tee design eliminates the need for separate adapters at the branch leg.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design — tubing seats and locks without tools or thread compound\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) body rated to 300 psi\u003c\/li\u003e\n  \u003cli\u003eAccepts 5\/16-inch OD tubing on all three ports\u003c\/li\u003e\n  \u003cli\u003eTan color for quick visual identification on the job\u003c\/li\u003e\n  \u003cli\u003eCompact union tee geometry for tight-space routing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect replacement or new-installation tee fitting for systems using 5\/16-inch OD tubing in low-to-medium pressure fluid or pneumatic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut off system pressure and depressurize the line before removing or installing any fitting. Ensure tubing ends are cut square and deburred so they seat fully in the collet — an incomplete seat is the leading cause of push-to-connect leaks. Verify that tubing OD is within the manufacturer tolerance for 5\/16-inch collet fittings before assembly. To release tubing, press the collet ring toward the fitting body while pulling the tube out; never pull tubing without releasing the collet.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-To-Connect, Tube to Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Configuration\u003c\/strong\u003e: Union Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A5TU5-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542818980146,"sku":"A5TU5-MG","price":23.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f04e8e530b40ce4ee5eccd9c2618b164.jpg?v=1785908303","url":"https:\/\/voomisupply.com\/products\/parker-a5tu5-mg-push-to-connect-union-tee-5-16-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
